fix: address issue #30340

docs(paste): add AI preview credit documentation

```markdown
## Summary of the Pull Request

Adds documentation clarifying that the "Show preview" setting for Paste with AI does not consume additional AI credits. The preview displays the same AI response that was already generated from a single API call, cached locally.

## Detailed Description of the Pull Request / Additional comments

This PR addresses the question raised in issue #32950 about whether enabling preview for Paste with AI costs extra AI quota.

Changes to `doc/devdocs/modules/advancedpaste.md`:
- Added new "Paste with AI Preview" section explaining:
  - The `ShowCustomPreview` setting behavior
  - Confirmation that preview does **not** consume additional AI credits
  - The implementation flow showing a single API call with local caching
  - Reference to `OptionsViewModel.cs` lines 702-717
- Added settings documentation table for `ShowCustomPreview`

Fixes #32950

## Validation Steps Performed

- Verified documentation renders correctly in Markdown preview
- Confirmed technical accuracy by referencing `OptionsViewModel.cs` implementation
```

+# Issue Fix Skill
+
+Automatically fix GitHub issues by creating isolated worktrees and applying AI-generated code changes based on implementation plans.
+
+## Skill Contents
+
+This skill is **self-contained** with all required resources:
+
+```
+.github/skills/issue-fix/
+├── SKILL.md              # This file
+├── LICENSE.txt           # MIT License
+├── scripts/
+│   └── Start-IssueAutoFix.ps1  # Main fix script
+└── references/
+    └── fix-issue.prompt.md     # Full AI prompt template
+```
+
+## Output Directory
+
+Worktrees are created at the drive root level:
+
+```
+Q:/PowerToys-xxxx/           # Worktree for issue (xxxx = short hash)
+├── Generated Files/
+│   └── issueReview/
+│       └── <issue-number>/  # Copied from main repo
+│           ├── overview.md
+│           └── implementation-plan.md
+└── <normal repo structure>
+```
+
+## When to Use This Skill
+
+- Fix a specific GitHub issue automatically
+- Implement a feature described in an issue
+- Apply an existing implementation plan
+- Create code changes for an issue
+- Auto-fix high-confidence issues
+- Resolve issues that have been reviewed
+
+## Prerequisites
+
+- GitHub CLI (`gh`) installed and authenticated
+- Issue must be reviewed first (use `issue-review` skill)
+- PowerShell 7+ for running scripts
+- Copilot CLI or Claude CLI installed
+
+## Required Variables
+
+⚠️ **Before starting**, confirm `{{IssueNumber}}` with the user. If not provided, **ASK**: "What issue number should I fix?"
+
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `{{IssueNumber}}` | GitHub issue number to fix | `44044` |
+
+## Workflow
+
+### Step 1: Ensure Issue is Reviewed
+
+If not already reviewed, use the `issue-review` skill first.
+
+### Step 2: Run Auto-Fix
+
+Execute the fix script (use paths relative to this skill folder):
+
+```powershell
+# From repo root
+.github/skills/issue-fix/scripts/Start-IssueAutoFix.ps1 -IssueNumber {{IssueNumber}} -CLIType copilot
+```
+
+This will:
+1. Create a new git worktree with branch `issue/{{IssueNumber}}`
+2. Copy the review files to the worktree
+3. Launch Copilot CLI to implement the fix
+4. Build and verify the changes
+
+### Step 3: Verify Changes
+
+Navigate to the worktree and review:
+
+```powershell
+# List worktrees
+git worktree list
+
+# Check changes in the worktree
+cd Q:/PowerToys-xxxx
+git diff
+git status
+```
+
+## CLI Options
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `-IssueNumber` | Issue to fix | Required |
+| `-CLIType` | AI CLI to use: `copilot` or `claude` | `copilot` |
+| `-Force` | Skip confirmation prompts | `false` |
+
+## Batch Fix
+
+To fix multiple issues:
+
+```powershell
+.github/skills/issue-fix/scripts/Start-IssueAutoFix.ps1 -IssueNumbers 44044, 32950 -CLIType copilot -Force
+```
+
+## After Fixing
+
+Once the fix is complete, use the `submit-pr` skill to create a PR.
+
+## AI Prompt Reference
+
+For manual AI invocation, the full prompt is at:
+- `references/fix-issue.prompt.md` (relative to this skill folder)
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| Worktree already exists | Use existing worktree or delete with `git worktree remove <path>` |
+| No implementation plan | Use `issue-review` skill first |
+| Build failures | Check build logs, may need manual intervention |
+| CLI not found | Install Copilot CLI |

+# Fix GitHub Issue
+
+## Dependencies
+Source review prompt (for generating the implementation plan if missing):
+- .github/prompts/review-issue.prompt.md
+
+Required plan file (single source of truth):
+- Generated Files/issueReview/{{issue_number}}/implementation-plan.md
+
+## Dependency Handling
+1) If `implementation-plan.md` exists → proceed.
+2) If missing → run the review prompt:
+   - Invoke: `.github/prompts/review-issue.prompt.md`
+   - Pass: `issue_number={{issue_number}}`
+   - Then re-check for `implementation-plan.md`.
+3) If still missing → stop and generate:
+   - `Generated Files/issueFix/{{issue_number}}/manual-steps.md` containing:
+     “implementation-plan.md not found; please run .github/prompts/review-issue.prompt.md for #{{issue_number}}.”
+
+# GOAL
+For **#{{issue_number}}**:
+- Use implementation-plan.md as the single authority.
+- Apply code and test changes directly in the repository.
+- Produce a PR-ready description.
+
+# OUTPUT FILES
+1) Generated Files/issueFix/{{issue_number}}/pr-description.md
+2) Generated Files/issueFix/{{issue_number}}/manual-steps.md   # only if human interaction or external setup is required
+
+# EXECUTION RULES
+1) Read implementation-plan.md and execute:
+   - Layers & Files → edit/create as listed
+   - Pattern Choices → follow repository conventions
+   - Fundamentals (perf, security, compatibility, accessibility)
+   - Logging & Exceptions
+   - Telemetry (only if explicitly included in the plan)
+   - Risks & Mitigations
+   - Tests to Add
+2) Locate affected files via `rg` or `git grep`.
+3) Add/update tests to enforce the fixed behavior.
+4) If any ambiguity exists, add:
+// TODO(Human input needed): <clarification needed>
+5) Verify locally: build & tests run successfully.
+
+# pr-description.md should include:
+- Title: `Fix: <short summary> (#{{issue_number}})`
+- What changed and why the fix works
+- Files or modules touched
+- Risks & mitigations (implemented)
+- Tests added/updated and how to run them
+- Telemetry behavior (if applicable)
+- Validation / reproduction steps
+- `Closes #{{issue_number}}`
+
+# manual-steps.md (only if needed)
+- List required human actions: secrets, config, approvals, missing info, or code comments requiring human decisions.
+
+# IMPORTANT
+- Apply code and tests directly; do not produce patch files.
+- Follow implementation-plan.md as the source of truth.
+- Insert comments for human review where a decision or input is required.
+- Use repository conventions and deterministic, minimal changes.
+
+# FINALIZE
+- Write pr-description.md
+- Write manual-steps.md only if needed
+- Print concise success message or note items requiring human interaction

+.SYNOPSIS
+    Auto-fix high-confidence issues using worktrees and AI CLI.
+
+.DESCRIPTION
+    Finds issues with high confidence scores from the review results, creates worktrees
+    for each, copies the Generated Files, and kicks off the FixIssue agent to implement fixes.
+
+.PARAMETER IssueNumber
+    Specific issue number to fix. If not specified, finds high-confidence issues automatically.
+
+.PARAMETER MinFeasibilityScore
+    Minimum Technical Feasibility score (0-100). Default: 70.
+
+.PARAMETER MinClarityScore
+    Minimum Requirement Clarity score (0-100). Default: 60.
+
+.PARAMETER MaxEffortDays
+    Maximum effort estimate in days. Default: 2 (Small fixes).
+
+.PARAMETER MaxParallel
+    Maximum parallel fix jobs. Default: 5 (worktrees are resource-intensive).
+
+.PARAMETER CLIType
+    AI CLI to use: claude, gh-copilot, or vscode. Auto-detected if not specified.
+
+.PARAMETER DryRun
+    List issues without starting fixes.
+
+.PARAMETER SkipWorktree
+    Fix in the current repository instead of creating worktrees (useful for single issue).
+
+.PARAMETER VSCodeProfile
+    VS Code profile to use when opening worktrees. Default: Default.
+
+.PARAMETER AutoCommit
+    Automatically commit changes after successful fix.
+
+.PARAMETER CreatePR
+    Automatically create a pull request after successful fix.
+
+.EXAMPLE
+    # Fix a specific issue
+    ./Start-IssueAutoFix.ps1 -IssueNumber 12345
+
+.EXAMPLE
+    # Find and fix all high-confidence issues (dry run)
+    ./Start-IssueAutoFix.ps1 -DryRun
+
+.EXAMPLE
+    # Fix issues with very high confidence
+    ./Start-IssueAutoFix.ps1 -MinFeasibilityScore 80 -MinClarityScore 70 -MaxEffortDays 1

+
+.NOTES
+    Prerequisites:
+    - Run Start-BulkIssueReview.ps1 first to generate review files
+    - GitHub CLI (gh) authenticated
+    - Claude Code CLI or VS Code with Copilot
+    
+    Results:
+    - Worktrees created at ../<RepoName>-<hash>/
+    - Generated Files copied to each worktree

+
+## When to Use This Skill
+
+- Review a specific GitHub issue for feasibility
+- Analyze whether an issue can be fixed by AI
+- Create an implementation plan for an issue
+- Triage issues by complexity and clarity
+- Estimate effort for fixing an issue
+- Evaluate technical requirements of an issue
+
+## Prerequisites
+
+- GitHub CLI (`gh`) installed and authenticated
+- PowerShell 7+ for running scripts
+
+## Required Variables
+
+⚠️ **Before starting**, confirm `{{IssueNumber}}` with the user. If not provided, **ASK**: "What issue number should I review?"
+
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `{{IssueNumber}}` | GitHub issue number to analyze | `44044` |
+
+## Workflow
+
+### Step 1: Run Issue Review
+
+Execute the review script (use paths relative to this skill folder):
+
+```powershell
+# From repo root
+.github/skills/issue-review/scripts/Start-BulkIssueReview.ps1 -IssueNumber {{IssueNumber}}
+```
+
+This will:
+1. Fetch issue details from GitHub
+2. Analyze the codebase for relevant files
+3. Generate `overview.md` with feasibility assessment
+4. Generate `implementation-plan.md` with detailed steps
+
+### Step 2: Review Output
+
+Check the generated files at `Generated Files/issueReview/{{IssueNumber}}/`:
+
+| File | Contains |
+|------|----------|
+| `overview.md` | Feasibility score (0-100), Clarity score (0-100), Effort estimate, Risk assessment |
+| `implementation-plan.md` | Step-by-step implementation with file paths, code snippets, test requirements |
+
+### Step 3: Interpret Scores
+
+| Score Range | Interpretation |
+|-------------|----------------|
+| 80-100 | High confidence - straightforward fix |
+| 60-79 | Medium confidence - some complexity |
+| 40-59 | Low confidence - significant challenges |
+| 0-39 | Very low - may need human intervention |
+
+## Batch Review
+
+To review multiple issues at once:
+
+```powershell
+.github/skills/issue-review/scripts/Start-BulkIssueReview.ps1 -IssueNumbers 44044, 32950, 45029
+```
+
+## AI Prompt Reference
+
+For manual AI invocation, the full prompt is at:
+- `references/review-issue.prompt.md` (relative to this skill folder)
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| Issue not found | Verify issue number exists: `gh issue view {{IssueNumber}}` |
+| No implementation plan | Issue may be unclear - check `overview.md` for clarity score |
+| Script errors | Ensure you're in the PowerToys repo root |

+
+# Review GitHub Issue
+
+## Goal
+For **#{{issue_number}}** produce:
+1) `Generated Files/issueReview/{{issue_number}}/overview.md`
+2) `Generated Files/issueReview/{{issue_number}}/implementation-plan.md`
+
+## Inputs
+Figure out required inputs {{issue_number}} from the invocation context; if anything is missing, ask for the value or note it as a gap.
+
+# CONTEXT (brief)
+Ground evidence using `gh issue view {{issue_number}} --json number,title,body,author,createdAt,updatedAt,state,labels,milestone,reactions,comments,linkedPullRequests`, download images via MCP `github_issue_images` to better understand the issue context. Finally, use MCP `github_issue_attachments` to download logs with parameter `extractFolder` as `Generated Files/issueReview/{{issue_number}}/logs`, and analyze the downloaded logs if available to identify relevant issues. Locate the source code in the current workspace (use `rg`/`git grep` as needed). Link related issues and PRs.
+
+## When to call MCP tools
+If the following MCP "github-artifacts" tools are available in the environment, use them:
+- `github_issue_images`: use when the issue/PR likely contains screenshots or other visual evidence (UI bugs, glitches, design problems).
+- `github_issue_attachments`: use when the issue/PR mentions attached ZIPs (PowerToysReport_*.zip, logs.zip, debug.zip) or asks to analyze logs/diagnostics. Always provide `extractFolder` as `Generated Files/issueReview/{{issue_number}}/logs`
+
+If these tools are not available (not listed by the runtime), start the MCP server "github-artifacts" first.

+Type/level: bug/feature/chore/docs/refactor/test-only; severity/value tier.
+
+## Suggested Actions
+Provide actionable recommendations for issue triage and assignment:
+
+### A) Requirement Clarification (if Clarity score <50)
+**When Requirement Clarity (Dimension D) is Medium or Low:**
+- Identify specific gaps in issue description: missing repro steps, unclear expected behavior, undefined acceptance criteria, missing non-functional requirements
+- Draft 3-5 clarifying questions to post as issue comment
+- Suggest additional information needed: screenshots, logs, environment details, OS version, PowerToys version, error messages
+- If behavior is ambiguous, propose 2-3 interpretation scenarios and ask reporter to confirm
+- Example questions:
+  - "Can you provide exact steps to reproduce this issue?"
+  - "What is the expected behavior vs. what you're actually seeing?"
+  - "Does this happen on Windows 10, 11, or both?"
+  - "Can you attach a screenshot or screen recording?"
+
+### B) Correct Label Suggestions
+- Analyze issue type, module, and severity to suggest missing or incorrect labels
+- Recommend labels from: `Issue-Bug`, `Issue-Feature`, `Issue-Docs`, `Issue-Task`, `Priority-High`, `Priority-Medium`, `Priority-Low`, `Needs-Triage`, `Needs-Author-Feedback`, `Product-<ModuleName>`, etc.
+- If Requirement Clarity is low (<50), add `Needs-Author-Feedback` label
+- If current labels are incorrect or incomplete, provide specific label changes with rationale
+
+### C) Find Similar Issues & Past Fixes
+- Search for similar issues using `gh issue list --search "keywords" --state all --json number,title,state,closedAt`
+- Identify patterns: duplicate issues, related bugs, or similar feature requests
+- For closed issues, find linked PRs that fixed them: check `linkedPullRequests` in issue data
+- Provide 3-5 examples of similar issues with format: `#<number> - <title> (closed by PR #<pr>)` or `(still open)`
+
+### D) Identify Subject Matter Experts
+- Use git blame/log to find who fixed similar issues in the past
+- Search for PR authors who touched relevant files: `git log --all --format='%aN' -- <file_paths> | sort | uniq -c | sort -rn | head -5`
+- Check issue/PR history for frequent contributors to the affected module
+- Suggest 2-3 potential assignees with context: `@<username> - <reason>` (e.g., "fixed similar rendering bug in #12345", "maintains FancyZones module")
+
+### E) Semantic Search for Related Work
+- Use semantic_search tool to find similar issues, code patterns, or past discussions
+- Search queries should include: issue keywords, module names, error messages, feature descriptions
+- Cross-reference semantic results with GitHub issue search for comprehensive coverage
+
+**Output format for Suggested Actions section in overview.md:**
+```markdown

+# IMPLEMENTATION-PLAN.MD
+1) **Problem Framing** — restate problem; current vs expected; scope boundaries.  
+2) **Layers & Files** — layers (UI/domain/data/infra/build). For each, list **files/dirs to modify** and **new files** (exact paths + why). Prefer repo patterns; cite examples/PRs.  
+3) **Pattern Choices** — reuse existing; if new, justify trade-offs & transition.  
+4) **Fundamentals** (brief plan or N/A + reason):
+- Performance (hot paths, allocs, caching/streaming)
+- Security (validation, authN/Z, secrets, SSRF/XSS/CSRF)
+- G11N/L10N (resources, number/date, pluralization)
+- Compatibility (public APIs, formats, OS/runtime/toolchain)
+- Extensibility (DI seams, options/flags, plugin points)
+- Accessibility (roles, labels, focus, keyboard, contrast)
+- SOLID & repo conventions (naming, folders, dependency direction)
+5) **Logging & Exception Handling**
+- Where to log; levels; structured fields; correlation/traces.
+- What to catch vs rethrow; retries/backoff; user-visible errors.
+- **Privacy**: never log secrets/PII; redaction policy.
+6) **Telemetry (optional — business metrics only)**
+- Events/metrics (name, when, props); success signal; privacy/sampling; dashboards/alerts.
+7) **Risks & Mitigations** — flags/canary/shadow-write/config guards.  
+8) **Task Breakdown (agent-ready)** — table (leave a blank line before the header so Markdown renders correctly):
+
+| Task | Intent | Files/Areas | Steps | Tests (brief) | Owner (Agent/Human) | Human interaction needed? (why) |
+|---|---|---|---|---|---|---|
+
+9) **Tests to Add (only)**
+- **Unit**: targets, cases (success/edge/error), mocks/fixtures, path, notes.  
+- **UI** (if applicable): flows, locator strategy, env/data/flags, path, flake mitigation.

+.SYNOPSIS
+    Bulk review GitHub issues using AI CLI (Claude Code or GitHub Copilot).
+
+.DESCRIPTION
+    Queries GitHub issues by labels, state, and sort order, then kicks off parallel
+    AI-powered reviews for each issue. Results are stored in Generated Files/issueReview/<number>/.
+
+.PARAMETER Labels
+    Comma-separated list of labels to filter issues (e.g., "bug,help wanted").
+
+.PARAMETER State
+    Issue state: open, closed, or all. Default: open.
+
+.PARAMETER Sort
+    Sort field: created, updated, comments, reactions. Default: created.
+
+.PARAMETER Order
+    Sort order: asc or desc. Default: desc.
+
+.PARAMETER Limit
+    Maximum number of issues to process. Default: 100.
+
+.PARAMETER MaxParallel
+    Maximum parallel review jobs. Default: 20.
+
+.PARAMETER CLIType
+    AI CLI to use: claude, gh-copilot, or vscode. Auto-detected if not specified.
+
+.PARAMETER DryRun
+    List issues without starting reviews.
+
+.PARAMETER SkipExisting
+    Skip issues that already have review files.
+
+.PARAMETER Repository
+    Repository in owner/repo format. Default: microsoft/PowerToys.
+
+.PARAMETER TimeoutMinutes
+    Timeout per issue review in minutes. Default: 30.
+
+.EXAMPLE
+    # Review all open bugs sorted by reactions
+    ./Start-BulkIssueReview.ps1 -Labels "bug" -Sort reactions -Order desc
+
+.EXAMPLE
+    # Dry run to see which issues would be reviewed
+    ./Start-BulkIssueReview.ps1 -Labels "help wanted" -DryRun
+
+.EXAMPLE
+    # Review top 50 issues with Claude Code, max 10 parallel
+    ./Start-BulkIssueReview.ps1 -Labels "Issue-Bug" -Limit 50 -MaxParallel 10 -CLIType claude
+
+.EXAMPLE
+    # Skip already-reviewed issues
+    ./Start-BulkIssueReview.ps1 -Labels "Issue-Feature" -SkipExisting
+
+.NOTES
+    Requires: GitHub CLI (gh) authenticated, and either Claude Code CLI or VS Code with Copilot.
+    Results: Generated Files/issueReview/<issue_number>/overview.md and implementation-plan.md

+
+**Note**: This skill orchestrates other skills via their PowerShell scripts:
+- `issue-review` skill scripts
+- `issue-fix` skill scripts
+- `submit-pr` skill scripts
+- `pr-review` skill scripts
+
+## Output
+
+The skill produces:
+1. Issue review files in `Generated Files/issueReview/<issue-number>/`
+2. Git worktrees with fixes at `Q:/PowerToys-xxxx/`
+3. Pull requests on GitHub
+4. PR review files in `Generated Files/prReview/<pr-number>/`
+
+## When to Use This Skill
+
+- Process multiple issues end-to-end automatically
+- Batch fix high-confidence issues
+- Run full automation cycle for triaged issues
+- Create PRs for multiple reviewed issues
+- Automate issue-to-PR workflow
+
+## Prerequisites
+
+- GitHub CLI (`gh`) installed and authenticated
+- Copilot CLI or Claude CLI installed
+- PowerShell 7+ for running scripts
+- Issues already reviewed (have `Generated Files/issueReview/` data)
+
+## Quick Start
+
+### Option 1: Dry Run First
+
+See what would be processed without making changes:
+
+```powershell
+# From repo root
+.github/skills/issue-to-pr-cycle/scripts/Start-FullIssueCycle.ps1 `
+    -MinFeasibilityScore 70 `
+    -MinClarityScore 70 `
+    -MaxEffortDays 10 `
+    -SkipExisting `
+    -DryRun
+```
+
+### Option 2: Run Full Cycle
+
+Process all matching issues:
+
+```powershell
+.github/skills/issue-to-pr-cycle/scripts/Start-FullIssueCycle.ps1 `
+    -MinFeasibilityScore 70 `
+    -MinClarityScore 70 `
+    -MaxEffortDays 10 `
+    -SkipExisting `
+    -CLIType copilot `
+    -Force
+```
+
+## CLI Options
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `-MinFeasibilityScore` | Minimum technical feasibility score (0-100) | `70` |
+| `-MinClarityScore` | Minimum requirement clarity score (0-100) | `70` |
+| `-MaxEffortDays` | Maximum effort estimate in days | `10` |
+| `-ExcludeIssues` | Array of issue numbers to skip | `@()` |
+| `-SkipExisting` | Skip issues that already have PRs | `false` |
+| `-CLIType` | AI CLI to use: `copilot` or `claude` | `copilot` |
+| `-FixThrottleLimit` | Parallel limit for fix phase | `5` |
+| `-PRThrottleLimit` | Parallel limit for PR phase | `5` |
+| `-ReviewThrottleLimit` | Parallel limit for review phase | `3` |
+| `-DryRun` | Show what would be done | `false` |
+| `-Force` | Skip confirmation prompts | `false` |
+

+## Related Skills
+
+This skill orchestrates (via PowerShell, not skill-to-skill):
+
+| Skill | Script Location | Purpose |
+|-------|-----------------|---------|
+| `issue-review` | `.github/skills/issue-review/scripts/` | Analyze issues |
+| `issue-fix` | `.github/skills/issue-fix/scripts/` | Create fixes |
+| `submit-pr` | `.github/skills/submit-pr/scripts/` | Create PRs |
+| `pr-review` | `.github/skills/pr-review/scripts/` | Review PRs |
+
+You can use each skill independently for finer control.
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| No issues found | Lower score thresholds or run more issue reviews |
+| All issues skipped | Remove `-SkipExisting` or check for existing PRs |
+| Parallel failures | Reduce throttle limits |

+    1. Find high-confidence issues matching criteria
+    2. Create worktrees and run auto-fix for each issue
+    3. Commit changes and create PRs
+    4. Run PR review workflow (assign Copilot, review, fix comments)
+
+.PARAMETER MinFeasibilityScore
+    Minimum Technical Feasibility score. Default: 70.
+
+.PARAMETER MinClarityScore
+    Minimum Requirement Clarity score. Default: 70.
+
+.PARAMETER MaxEffortDays
+    Maximum effort in days. Default: 10.
+
+.PARAMETER ExcludeIssues
+    Array of issue numbers to exclude (already processed).
+
+.PARAMETER CLIType
+    AI CLI to use: copilot or claude. Default: copilot.
+
+.PARAMETER DryRun
+    Show what would be done without executing.
+
+.PARAMETER SkipExisting
+    Skip issues that already have worktrees or PRs.

+
+## When to Use This Skill
+
+- Review a specific pull request
+- Analyze PR changes for quality issues
+- Post review comments on a PR
+- Validate PR against PowerToys standards
+- Run comprehensive code review
+
+## Prerequisites
+
+- GitHub CLI (`gh`) installed and authenticated
+- PowerShell 7+ for running scripts
+- GitHub MCP configured (for posting comments)
+
+## Required Variables
+
+⚠️ **Before starting**, confirm `{{PRNumber}}` with the user. If not provided, **ASK**: "What PR number should I review?"
+
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `{{PRNumber}}` | Pull request number to review | `45234` |
+
+## Workflow
+
+### Step 1: Run PR Review
+
+Execute the review workflow (use paths relative to this skill folder):
+
+```powershell
+# From repo root
+.github/skills/pr-review/scripts/Start-PRReviewWorkflow.ps1 -PRNumbers {{PRNumber}} -CLIType copilot
+```
+
+This will:
+1. Optionally assign GitHub Copilot as reviewer
+2. Fetch PR diff and changed files
+3. Generate 13 review step files
+4. Post findings as review comments
+
+### Step 2: Review Output
+
+Check the generated files at `Generated Files/prReview/{{PRNumber}}/`
+
+## CLI Options
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `-PRNumbers` | PR number(s) to review | From worktrees |
+| `-CLIType` | AI CLI to use: `copilot` or `claude` | `copilot` |
+| `-MinSeverity` | Min severity to post: `high`, `medium`, `low`, `info` | `medium` |
+| `-SkipAssign` | Skip assigning Copilot as reviewer | `false` |
+| `-SkipReview` | Skip the review step | `false` |
+| `-SkipFix` | Skip the fix step | `false` |
+| `-MaxParallel` | Maximum parallel jobs | `3` |
+| `-Force` | Skip confirmation prompts | `false` |
+
+## AI Prompt References
+
+For manual AI invocation, prompts are at:
+- `references/review-pr.prompt.md` - Full review instructions
+- `references/fix-pr-active-comments.prompt.md` - Comment fix instructions
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| PR not found | Verify PR number: `gh pr view {{PRNumber}}` |
+| Review incomplete | Check `_copilot-review.log` for errors |
+| Comments not posted | Ensure GitHub MCP is configured |

+
+# Fix Active PR Comments
+
+## Mission
+Resolve active pull request comments by applying only simple fixes. For complex refactors, write a plan instead of changing code.
+
+## Scope & Preconditions
+- You must have an active pull request context or a provided PR number.
+- Only implement simple changes. Do not implement large refactors.
+- If required context is missing, request it and stop.
+
+## Inputs
+- Required: ${input:pr_number:PR number or URL}
+- Optional: ${input:comment_scope:files or areas to focus on}
+- Optional: ${input:fixing_guidelines:additional fixing guidelines from the user}
+
+## Workflow
+1. Locate all active (unresolved) PR review comments for the given PR.
+2. For each comment, classify the change scope:
+   - Simple change: limited edits, localized fix, low risk, no broad redesign.
+   - Large refactor: multi-file redesign, architecture change, or risky behavior change.
+3. For each large refactor request:
+   - Do not modify code.
+   - Write a planning document to Generated Files/prReview/${input:pr_number}/fixPlan/.
+4. For each simple change request:
+   - Implement the fix with minimal edits.
+   - Run quick checks if needed.
+   - Commit and push the change.
+5. For comments that seem invalid, unclear, or not applicable (even if simple):
+   - Do not change code.
+   - Add the item to a summary table in Generated Files/prReview/${input:pr_number}/fixPlan/overview.md.
+   - Consult back to the end user in a friendly, polite tone.
+6. Respond to each comment that you fixed:
+   - Reply in the active conversation.
+   - Use a polite or friendly tone.
+   - Keep the response under 200 words.
+   - Resolve the comment after replying.
+
+## Output Expectations
+- Simple fixes: code changes committed and pushed.
+- Large refactors: a plan file saved to Generated Files/prReview/${input:pr_number}/fixPlan/.
+- Invalid or unclear comments: captured in Generated Files/prReview/${input:pr_number}/fixPlan/overview.md.
+- Each fixed comment has a reply under 200 words and is resolved.
+
+## Plan File Template
+Use this template for each large refactor item:
+
+# Fix Plan: <short title>
+
+## Context
+- Comment link:
+- Impacted areas:
+
+## Overview Table Template
+Use this table in Generated Files/prReview/${input:pr_number}/fixPlan/overview.md:
+
+| Comment link | Summary | Reason not applied | Suggested follow-up |
+| --- | --- | --- | --- |
+|  |  |  |  |
+
+## Quality Assurance
+- Verify plan file path exists.
+- Ensure no code changes were made for large refactor items.
+- Confirm replies are under 200 words and comments are resolved.

+
+# Review Pull Request
+
+**Goal**: Given `{{pr_number}}`, run a *one-topic-per-step* review. Write files to `Generated Files/prReview/{{pr_number}}/` (replace `{{pr_number}}` with the integer). Emit machine‑readable blocks for a GitHub MCP to post review comments.
+
+## PR selection
+Resolve the target PR using these fallbacks in order:
+1. Parse the invocation text for an explicit identifier (first integer following patterns such as a leading hash and digits or the text `PR:` followed by digits).
+2. If no PR is found yet, locate the newest `Generated Files/prReview/_batch/batch-overview-*.md` file (highest timestamp in filename, fallback newest mtime) and take the first entry in its `## PRs` list whose review folder is missing `00-OVERVIEW.md` or contains `__error.flag`.
+3. If the batch file has no pending PRs, query assignments with `gh pr list --assignee @me --state open --json number,updatedAt --limit 20` and pick the most recently updated PR that does not already have a completed review folder.
+4. If still unknown, run `gh pr view --json number` in the current branch and use that result when it is unambiguous.
+5. If every step above fails, prompt the user for a PR number before proceeding.
+
+## Fetch PR data with `gh`
+- `gh pr view {{pr_number}} --json number,baseRefName,headRefName,baseRefOid,headRefOid,changedFiles,files`
+- `gh api repos/:owner/:repo/pulls/{{pr_number}}/files?per_page=250`  # patches for line mapping
+
+### Incremental review workflow
+1. **Check for existing review**: Read `Generated Files/prReview/{{pr_number}}/00-OVERVIEW.md`
+2. **Extract state**: Parse `Last reviewed SHA:` from review metadata section
+3. **Detect changes**: Run `Get-PrIncrementalChanges.ps1 -PullRequestNumber {{pr_number}} -LastReviewedCommitSha {{sha}}`
+4. **Analyze result**:
+   - `NeedFullReview: true` → Review all files in the PR
+   - `NeedFullReview: false` and `IsIncremental: true` → Review only files in `ChangedFiles` array
+   - `ChangedFiles` is empty → No changes, skip review (update iteration history with "No changes since last review")
+5. **Apply smart filtering**: Use the file patterns in smart step filtering table to skip irrelevant steps
+6. **Update metadata**: After completing review, save current `headRefOid` as `Last reviewed SHA:` in `00-OVERVIEW.md`
+
+### Reusable PowerShell scripts
+Scripts live in `.github/review-tools/` to avoid repeated manual approvals during PR reviews:
+
+| Script | Usage |
+| --- | --- |
+| `.github/review-tools/Get-GitHubRawFile.ps1` | Download a repository file at a given ref, optionally with line numbers. |
+| `.github/review-tools/Get-GitHubPrFilePatch.ps1` | Fetch the unified diff for a specific file within a pull request via `gh api`. |
+| `.github/review-tools/Get-PrIncrementalChanges.ps1` | Compare last reviewed SHA with current PR head to identify incremental changes. Returns JSON with changed files, new commits, and whether full review is needed. |
+| `.github/review-tools/Test-IncrementalReview.ps1` | Test helper to preview incremental review detection for a PR. Use before running full review to see what changed. |
+
+Always prefer these scripts (or new ones added under `.github/review-tools/`) over raw `gh api` or similar shell commands so the review flow does not trigger interactive approval prompts.
+
+## Output files
+Folder: `Generated Files/prReview/{{pr_number}}/`
+Files: `00-OVERVIEW.md`, `01-functionality.md`, `02-compatibility.md`, `03-performance.md`, `04-accessibility.md`, `05-security.md`, `06-localization.md`, `07-globalization.md`, `08-extensibility.md`, `09-solid-design.md`, `10-repo-patterns.md`, `11-docs-automation.md`, `12-code-comments.md`, `13-copilot-guidance.md` *(only if guidance md exists).* 
+- **Write-after-step rule:** Immediately after completing each TODO step, persist that step's markdown file before proceeding to the next. Generate `00-OVERVIEW.md` only after every step file has been refreshed for the current run.
+
+## Iteration management
+- Determine the current review iteration by reading `00-OVERVIEW.md` (look for `Review iteration:`). If missing, assume iteration `1`.
+- Extract the last reviewed SHA from `00-OVERVIEW.md` (look for `Last reviewed SHA:` in the review metadata section). If missing, this is iteration 1.
+- **Incremental review detection**:
+  1. Call `.github/review-tools/Get-PrIncrementalChanges.ps1 -PullRequestNumber {{pr_number}} -LastReviewedCommitSha {{last_sha}}` to get delta analysis.
+  2. Parse the JSON result to determine if incremental review is possible (`IsIncremental: true`, `NeedFullReview: false`).
+  3. If force-push detected or first review, proceed with full review of all changed files.
+  4. If incremental, review only the files listed in `ChangedFiles` array and apply smart step filtering (see below).
+- Increment the iteration for each review run and propagate the new value to all step files and the overview.
+- Preserve prior iteration notes by keeping/expanding an `## Iteration history` section in each markdown file, appending the newest summary under `### Iteration <N>`.
+- Summaries should capture key deltas since the previous iteration so reruns can pick up context quickly.
+- **After review completion**, update `Last reviewed SHA:` in `00-OVERVIEW.md` with the current `headRefOid` and update the timestamp.
+
+### Smart step filtering (incremental reviews only)
+When performing incremental review, skip steps that are irrelevant based on changed file types:
+
+| File pattern | Required steps | Skippable steps |
+| --- | --- | --- |
+| `**/*.cs`, `**/*.cpp`, `**/*.h` | Functionality, Compatibility, Performance, Security, SOLID, Repo patterns, Code comments | (depends on files) |
+| `**/*.resx`, `**/Resources/*.xaml` | Localization, Globalization | Most others |
+| `**/*.md` (docs) | Docs & automation | Most others (unless copilot guidance) |
+| `**/*copilot*.md`, `.github/prompts/*.md` | Copilot guidance, Docs & automation | Most others |
+| `**/*.csproj`, `**/*.vcxproj`, `**/packages.config` | Compatibility, Security, Repo patterns | Localization, Globalization, Accessibility |
+| `**/UI/**`, `**/*View.xaml` | Accessibility, Localization | Performance (unless perf-sensitive controls) |
+
+**Default**: If uncertain or files span multiple categories, run all applicable steps. When in doubt, be conservative and review more rather than less.
+
+## TODO steps (one concern each)
+1) Functionality
+2) Compatibility
+3) Performance
+4) Accessibility
+5) Security
+6) Localization
+7) Globalization
+8) Extensibility
+9) SOLID principles
+10) Repo patterns
+11) Docs & automation coverage for the changes
+12) Code comments
+13) Copilot guidance (conditional): if changed folders contain `*copilot*.md` or `.github/prompts/*.md`, review diffs **against** that guidance and write `13-copilot-guidance.md` (omit if none).
+
+## Per-step file template (use verbatim)
+```md
+# <STEP TITLE>
+**PR:** (populate with PR identifier) — Base:<baseRefName> Head:<headRefName>
+**Review iteration:** ITERATION
+
+## Iteration history
+- Maintain subsections titled `### Iteration N` in reverse chronological order (append the latest at the top) with 2–4 bullet highlights.
+
+### Iteration ITERATION
+- <Latest key point 1>
+- <Latest key point 2>
+
+## Checks executed
+- List the concrete checks for *this step only* (5–10 bullets).
+
+## Findings
+(If none, write **None**. Defaults have one or more blocks:)
+
+```mcp-review-comment
+{"file":"relative/path.ext","start_line":123,"end_line":125,"severity":"high|medium|low|info","tags":["<step-slug>","pr-tag-here"],"related_files":["optional/other/file1"],"body":"Problem → Why it matters → Concrete fix. If spans multiple files, name them here."}
+```
+Use the second tag to encode the PR number.
+
+```
+## Overview file (`00-OVERVIEW.md`) template
+```md
+# PR Review Overview — (populate with PR identifier)
+**Review iteration:** ITERATION
+**Changed files:** <n> | **High severity issues:** <count>
+
+## Review metadata
+**Last reviewed SHA:** <headRefOid from gh pr view>
+**Last review timestamp:** <ISO8601 timestamp>
+**Review mode:** <Full|Incremental (N files changed since iteration X)>
+**Base ref:** <baseRefName>
+**Head ref:** <headRefName>
+
+## Step results
+Write lines like: `01 Functionality — <OK|Issues|Skipped> (see 01-functionality.md)` … through step 13.
+Mark steps as "Skipped" when using incremental review smart filtering.
+
+## Iteration history
+- Maintain subsections titled `### Iteration N` mirroring the per-step convention with concise deltas and cross-links to the relevant step files.
+- For incremental reviews, list the specific files that changed and which commits were added.
+```
+
+## Line numbers & multi‑file issues
+- Map head‑side lines from `patch` hunks (`@@ -a,b +c,d @@` → new lines `+c..+c+d-1`).
+- For cross‑file issues: set the primary `"file"`, list others in `"related_files"`, and name them in `"body"`.
+
+## Posting (for MCP)
+- Parse all ```mcp-review-comment``` blocks across step files and post as PR review comments.
+- If posting isn’t available, still write all files.
+
+## Constraint
+Read/analyze only; don't modify code. Keep comments small, specific, and fix‑oriented.
+
+**Testing**: Use `.github/review-tools/Test-IncrementalReview.ps1 -PullRequestNumber 42374` to preview incremental detection before running full review.
+
+## Scratch cache for large PRs
+
+Create a local scratch workspace to progressively summarize diffs and reload state across runs.
+
+### Paths
+- Root: `Generated Files/prReview/{{pr_number}}/__tmp/`
+- Files:
+  - `index.jsonl` — append-only JSON Lines index of artifacts.
+  - `todo-queue.json` — pending items (files/chunks/steps).
+  - `rollup-<step>-v<N>.md` — iterative per-step aggregates.
+  - `file-<hash>.txt` — optional saved chunk text (when needed).
+
+### JSON schema (per line in `index.jsonl`)
+```json
+{"type":"chunk|summary|issue|crosslink",
+ "path":"relative/file.ext","chunk_id":"f-12","step":"functionality|compatibility|...",
+ "base_sha":"...", "head_sha":"...", "range":[start,end], "version":1,
+ "notes":"short text or key:value map", "created_utc":"ISO8601"}
+```
+
+### Phases (stateful; resume-safe)
+0. **Discover** PR + SHAs: `gh pr view <PR> --json baseRefName,headRefName,baseRefOid,headRefOid,files`.
+1. **Chunk** each changed file (head): split into ~300–600 LOC or ~4k chars; stable `chunk_id` = hash(path+start).
+   - Save `chunk` records. Optionally write `file-<hash>.txt` for expensive chunks.
+2. **Summarize** per chunk: intent, APIs, risks per TODO step; emit `summary` records (≤600 tokens each).
+3. **Issues**: convert findings to machine-readable blocks and emit `issue` records (later rendered to step MD).
+4. **Rollups**: build/update `rollup-<step>-v<N>.md` from `summary`+`issue`. Keep prior versions.
+5. **Finalize**: write per-step files + `00-OVERVIEW.md` from rollups. Post comments via MCP if available.
+
+### Re-use & token limits
+- Always **reload** `index.jsonl` first; skip chunks with same `head_sha` and `range`.
+- **Incremental review optimization**: When `Get-PrIncrementalChanges.ps1` returns a subset of changed files, load only chunks from those files. Reuse existing chunks/summaries for unchanged files.
+- Prefer re-summarizing only changed chunks; merge chunk summaries → file summaries → step rollups.
+- When context is tight, load only the minimal chunk text (or its saved `file-<hash>.txt`) needed for a comment.
+
+### Original vs diff
+- Fetch base content when needed: prefer `git show <baseRefName>:<path>`; fallback `gh api repos/:owner/:repo/contents/<path>?ref=<base_sha>` (base64).
+- Use patch hunks from `gh api .../pulls/<PR>/files` to compute **head** line numbers.
+
+### Queue-driven loop
+- Seed `todo-queue.json` with all changed files.
+- Process: chunk → summarize → detect issues → roll up.
+- Append to `index.jsonl` after each step; never rewrite previous lines (append-only).
+
+### Hygiene
+- `__tmp/` is implementation detail; do not include in final artifacts.
+- It is safe to delete to force a clean pass; the next run rebuilds it.

+<#
+.SYNOPSIS
+    Detects changes between the last reviewed commit and current head of a pull request.
+
+.DESCRIPTION
+    This script compares a previously reviewed commit SHA with the current head of a pull request
+    to determine what has changed. It helps enable incremental reviews by identifying new commits
+    and modified files since the last review iteration.
+
+    The script handles several scenarios:
+    - First review (no previous SHA provided)
+    - No changes (current SHA matches last reviewed SHA)
+    - Force-push detected (last reviewed SHA no longer in history)
+    - Incremental changes (new commits added since last review)
+
+.PARAMETER PullRequestNumber
+    The pull request number to analyze.
+
+.PARAMETER LastReviewedCommitSha
+    The commit SHA that was last reviewed. If omitted, this is treated as a first review.
+
+.PARAMETER RepositoryOwner
+    The GitHub repository owner. Defaults to "microsoft".
+
+.PARAMETER RepositoryName
+    The GitHub repository name. Defaults to "PowerToys".
+
+.OUTPUTS
+    JSON object containing:
+    - PullRequestNumber: The PR number being analyzed
+    - CurrentHeadSha: The current head commit SHA
+    - LastReviewedSha: The last reviewed commit SHA (if provided)
+    - BaseRefName: Base branch name
+    - HeadRefName: Head branch name
+    - IsIncremental: Boolean indicating if incremental review is possible
+    - NeedFullReview: Boolean indicating if a full review is required
+    - ChangedFiles: Array of files that changed (filename, status, additions, deletions)
+    - NewCommits: Array of commits added since last review (sha, message, author, date)
+    - Summary: Human-readable description of changes
+
+.EXAMPLE
+    .\Get-PrIncrementalChanges.ps1 -PullRequestNumber 42374
+    Analyzes PR #42374 with no previous review (first review scenario).
+
+.EXAMPLE
+    .\Get-PrIncrementalChanges.ps1 -PullRequestNumber 42374 -LastReviewedCommitSha "abc123def456"
+    Compares current PR state against the last reviewed commit to identify incremental changes.
+
+.EXAMPLE
+    $changes = .\Get-PrIncrementalChanges.ps1 -PullRequestNumber 42374 -LastReviewedCommitSha "abc123" | ConvertFrom-Json
+    if ($changes.IsIncremental) { Write-Host "Can perform incremental review" }
+    Captures the output as a PowerShell object for further processing.

+<#
+.SYNOPSIS
+    Tests and previews incremental review detection for a pull request.
+
+.DESCRIPTION
+    This helper script validates the incremental review detection logic by analyzing an existing
+    PR review folder. It reads the last reviewed SHA from the overview file, compares it with
+    the current PR state, and displays detailed information about what has changed.
+    
+    This is useful for:
+    - Testing the incremental review system before running a full review
+    - Understanding what changed since the last review iteration
+    - Verifying that review metadata was properly recorded
+
+.PARAMETER PullRequestNumber
+    The pull request number to test incremental review detection for.
+
+.PARAMETER RepositoryOwner
+    The GitHub repository owner. Defaults to "microsoft".
+
+.PARAMETER RepositoryName
+    The GitHub repository name. Defaults to "PowerToys".
+
+.OUTPUTS
+    Colored console output displaying:
+    - Current and last reviewed commit SHAs
+    - Whether incremental review is possible
+    - List of new commits since last review
+    - List of changed files with status indicators
+    - Recommended review strategy
+
+.EXAMPLE
+    .\Test-IncrementalReview.ps1 -PullRequestNumber 42374
+    Tests incremental review detection for PR #42374.
+
+.EXAMPLE
+    .\Test-IncrementalReview.ps1 -PullRequestNumber 42374 -RepositoryOwner "myorg" -RepositoryName "myrepo"
+    Tests incremental review for a PR in a different repository.
+
+.NOTES
+    Requires GitHub CLI (gh) to be installed and authenticated.
+    Run 'gh auth login' if not already authenticated.
+    
+    Prerequisites:
+    - PR review folder must exist at "Generated Files\prReview\{PRNumber}"
+    - 00-OVERVIEW.md must exist in the review folder
+    - For incremental detection, overview must contain "Last reviewed SHA" metadata

+1. Generate a commit title using AI (following conventional commits)
+2. Stage and commit all changes
+3. Push the branch to origin
+4. Generate a PR description using AI
+5. Create the PR on GitHub
+
+### Step 3: Review Created PR
+
+The script outputs the PR URL. Review it on GitHub.
+
+## CLI Options
+
+| Parameter | Description | Default |
+|-----------|-------------|---------|
+| `-IssueNumbers` | Issue number(s) to submit | All worktrees |
+| `-CLIType` | AI CLI to use: `copilot`, `claude`, or `manual` | `copilot` |
+| `-TargetBranch` | Base branch for PR | `main` |
+| `-Draft` | Create as draft PR | `false` |
+| `-Force` | Skip confirmation prompts | `false` |
+| `-DryRun` | Show what would be done | `false` |
+
+## PR Title Format
+
+Titles follow conventional commits (see `references/create-commit-title.prompt.md`):
+
+```
+<type>(<scope>): <description>
+```
+
+| Type | When to use |
+|------|-------------|
+| `fix` | Bug fixes |
+| `feat` | New features |
+| `docs` | Documentation only |
+| `refactor` | Code restructuring |
+
+## AI Prompt References
+
+For manual AI invocation, prompts are at:
+- `references/create-commit-title.prompt.md` - Commit title generation
+- `references/create-pr-summary.prompt.md` - PR description generation
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| No changes to commit | Verify fix was applied, check `git status` |
+| PR already exists | Script will skip and report existing PR URL |
+| Push rejected | Pull latest changes or force push with `--force-with-lease` |

+description: 'Generate an 80-character git commit title for the local diff'
+---
+
+# Generate Commit Title
+
+## Purpose
+Provide a single-line, ready-to-paste git commit title (<= 80 characters) that reflects the most important local changes since `HEAD`.
+
+## Input to collect
+- Run exactly one command to view the local diff:
+  ```@terminal
+  git diff HEAD
+  ```
+
+## How to decide the title
+1. From the diff, find the dominant area (e.g., `src/modules/*`, `doc/devdocs/**`) and the change type (bug fix, docs update, config tweak).
+2. Draft an imperative, plain-ASCII title that:
+   - Mentions the primary component when obvious (e.g., `FancyZones:` or `Docs:`)
+   - Stays within 80 characters and has no trailing punctuation
+
+## Final output
+- Reply with only the commit title on a single line—no extra text.
+
+## PR title convention (when asked)
+Use Conventional Commits style:
+
+`<type>(<scope>): <summary>`
+
+**Allowed types**
+- feat, fix, docs, refactor, perf, test, build, ci, chore
+
+**Scope rules**
+- Use a short, PowerToys-focused scope (one word preferred). Common scopes:
+  - Core: `runner`, `settings-ui`, `common`, `docs`, `build`, `ci`, `installer`, `gpo`, `dsc`
+  - Modules: `fancyzones`, `powerrename`, `awake`, `colorpicker`, `imageresizer`, `keyboardmanager`, `mouseutils`, `peek`, `hosts`, `file-locksmith`, `screen-ruler`, `text-extractor`, `cropandlock`, `paste`, `powerlauncher`
+- If unclear, pick the closest module or subsystem; omit only if unavoidable
+
+**Summary rules**
+- Imperative, present tense (“add”, “update”, “remove”, “fix”)
+- Keep it <= 72 characters when possible; be specific, avoid “misc changes”
+
+**Examples**
+- `feat(fancyzones): add canvas template duplication`
+- `fix(mouseutils): guard crosshair toggle when dpi info missing`
+- `docs(runner): document tray icon states`
+- `build(installer): align wix v5 suffix flag`
+- `ci(ci): cache pipeline artifacts for x64`

+description: 'Generate a PowerToys-ready pull request description from the local diff'
+---
+
+# Generate PR Summary
+
+**Goal:** Produce a ready-to-paste PR title and description that follows PowerToys conventions by comparing the current branch against a user-selected target branch.
+
+**Repo guardrails:**
+- Treat `.github/pull_request_template.md` as the single source of truth; load it at runtime instead of embedding hardcoded content in this prompt.
+- Preserve section order from the template but only surface checklist lines that are relevant for the detected changes, filling them with `[x]`/`[ ]` as appropriate.
+- Cite touched paths with inline backticks, matching the guidance in `.github/copilot-instructions.md`.
+- Call out test coverage explicitly: list automated tests run (unit/UI) or state why they are not applicable.
+
+**Workflow:**
+1. Determine the target branch from user context; default to `main` when no branch is supplied.
+2. Run `git status --short` once to surface uncommitted files that may influence the summary.
+3. Run `git diff <target-branch>...HEAD` a single time to review the detailed changes. Only when confidence stays low dig deeper with focused calls such as `git diff <target-branch>...HEAD -- <path>`.
+4. From the diff, capture impacted areas, key file changes, behavioral risks, migrations, and noteworthy edge cases.
+5. Confirm validation: list tests executed with results or state why tests were skipped in line with repo guidance.
+6. Load `.github/pull_request_template.md`, mirror its section order, and populate it with the gathered facts. Include only relevant checklist entries, marking them `[x]/[ ]` and noting any intentional omissions as "N/A".
+7. Present the filled template inside a fenced ```markdown code block with no extra commentary so it is ready to paste into a PR, clearly flagging any placeholders that still need user input.
+8. Prepend the PR title above the filled template, applying the Conventional Commit type/scope rules from `.github/prompts/create-commit-title.prompt.md`; pick the dominant component from the diff and keep the title concise and imperative.

+# 🧭 Creating a new PowerToy: end-to-end developer guide
+
+First of all, thank you for wanting to contribute to PowerToys. The work we do would not be possible without the support of community supporters like you.
+
+This guide documents the process of building a new PowerToys utility from scratch, including architecture decisions, integration steps, and common pitfalls.
+
+---
+
+## 1. Overview and prerequisites
+
+A PowerToy module is a self-contained utility integrated into the PowerToys ecosystem. It can be UI-based, service-based, or both.
+
+### Requirements
+
+- [Visual Studio 2026](https://visualstudio.microsoft.com/downloads/) and the following workloads/individual components:
+  - Desktop Development with C++
+  - WinUI application development
+  - .NET desktop development
+  - Windows 10 SDK (10.0.22621.0)
+  - Windows 11 SDK (10.0.26100.3916)
+- .NET 8 SDK
+- Fork the [PowerToys repository](https://github.com/microsoft/PowerToys/tree/main) locally
+- [Validate that you are able to build and run](https://github.com/microsoft/PowerToys/blob/main/doc/devdocs/development/debugging.md) `PowerToys.slnx`.
+
+Optional: 
+- [WiX v5 toolset](https://github.com/microsoft/PowerToys/tree/main) for the installer
+
+> [!NOTE]
+> To ensure all the correct VS Workloads are installed, use [the WinGet configuration files](https://github.com/microsoft/PowerToys/tree/e13d6a78aafbcf32a4bb5f8581d041e1d057c3f1/.config) in the project repository. (Use the one that matches your VS distribution. ie: VS Community would use `configuration.winget`)
+
+### Folder structure
+
+```
+src/
+  modules/
+    your_module/
+      YourModule.sln
+      YourModuleInterface/
+      YourModuleUI/ (if needed)
+      YourModuleService/ (if needed)
+```
+
+---
+## 2. Design and planning
+
+### Decide the type of module
+
+Think about how your module works and which existing modules behave similarly. You are going to want to think about the UI needed for the application, the lifecycle, whether it is a service that is always running or event based. Below are some basic scenarios with some modules to explore. You can write your application in C++ or C#.
+- **UI-only:** e.g., ColorPicker
+- **Background service:** e.g., LightSwitch, Awake
+- **Hybrid (UI + background logic):** e.g., ShortcutGuide
+- **C++/C# interop:** e.g., PowerRename 
+
+### Write your module interface
+
+Begin by setting up the [PowerToy module template project](https://github.com/microsoft/PowerToys/tree/main/tools/project_template). This will generate boilerplate for you to begin your new module. Below are the key headers in the Module Interface (`dllmain.cpp`) and an explanation of their purpose:
+1. This is where module settings are defined. These can be anything from strings, bools, ints, and even custom Enums.
+```c++
+struct ModuleSettings {};
+```
+
+2. This is the header for the full class. It inherits the PowerToyModuleIface
+```c++
+class ModuleInterface : public PowertoyModuleIface 
+{
+  private:
+    // the private members of the class
+    // Can include the enabled variable, logic for event handlers, or hotkeys.
+  public:
+    // the public members of the class
+    // Will include the constructor and initialization logic.
+}
+```
+
+> [!NOTE]
+> Many of the class functions are boilerplate and need simple string replacements with your module name. The rest of the functions below will require bigger changes.
+
+3. GPO stands for "Group Policy Object" and allows for administrators to configure settings across a network of machines. It is required that your module is on this list of settings. You can right click the `powertoys_gpo` object to go to the definition and set up the `getConfiguredModuleEnabledValue` for your module.
+```c++
+virtual powertoys_gpo::gpo_rule_configured_t gpo_policy_enabled_configuration() override
+{
+    return powertoys_gpo::getConfiguredModuleEnabledValue();
+}
+```
+
+4. `init_settings()` initializes the settings for the interface. Will either pull from existing settings.json or use defaults.
+```c++
+void ModuleInterface::init_settings()
+```
+
+5. `get_config` retrieves the settings from the settings.json file.
+```c++
+virtual bool get_config(wchar_t* buffer, int* buffer_size) override
+```
+
+6. `set_config` sets the new settings to the settings.json file.
+```c++
+virtual void set_config(const wchar_t* config) override
+```
+
+7. `call_custom_action` allows custom actions to be called based on signals from the settings app.
+```c++
+void call_custom_action(const wchar_t* action) override
+```
+
+8. Lifecycle events control whether the module is enabled or not, as well as the default status of the module.
+```c++
+virtual void enable() // starts the module
+virtual void disable() // terminates the module and performs any cleanup
+virtual bool is_enabled() // returns if the module is currently enabled
+virtual bool is_enabled_by_default() const override // allows the module to dictate whether it should be enabled by default in the PowerToys app.
+```
+
+9. Hotkey functions control the status of the hotkey.
+```c++
+// takes the hotkey from settings into a format that the interface can understand
+void parse_hotkey(PowerToysSettings::PowerToyValues& settings) 
+
+// returns the hotkeys from settings
+virtual size_t get_hotkeys(Hotkey* hotkeys, size_t buffer_size) override 
+
+// performs logic when the hotkey event is fired
+virtual bool on_hotkey(size_t hotkeyId) override 
+```
+
+### Notes
+
+- Keep module logic isolated under `/modules/<YourModule>`
+- Use shared utilities from [`common`](https://github.com/microsoft/PowerToys/tree/main/src/common) instead of cross-module dependencies
+- init/set/get config use preset functions to access the settings. Check out the [`settings_objects.h`](https://github.com/microsoft/PowerToys/blob/main/src/common/SettingsAPI/settings_helpers.h) in `src\common\SettingsAPI`
+
+---
+## 3. Bootstrapping your module
+
+1. Use the [template](https://github.com/microsoft/PowerToys/tree/main/tools/project_template) to generate the module interface starter code.
+2. Update all projects and namespaces with your module name.
+3. Update GUIDs in `.vcxproj` and solution files.
+4. Update the functions mentioned in the above section with your custom logic.
+5. In order for your module to be detected by the runner you are required to add  references to various lists. In order to register your module, add the corresponding module reference to the lists that can be found in the following files. (Hint: search other modules names to find the lists quicker)
+    - `src/runner/modules.h`
+    - `src/runner/modules.cpp`
+    - `src/runner/resource.h`
+    - `src/runner/settings_window.h`
+    - `src/runner/settings_window.cpp`
+    - `src/runner/main.cpp`
+    - `src/common/logger.h` (for logging)
+6. ModuleInterface should build your `ModuleInterface.dll`. This will allow the runner to interact with your service.
+
+> [!TIP]
+> Mismatched module IDs are one of the most common causes of load failures. Keep your ID consistent across manifest, registry, and service.
+
+---
+## 4. Write your service
+
+This is going to look different for every PowerToy. It may be easier to develop the application independently, and then link in the PowerToys settings logic later. But you have to write the service first, before connecting it to the runner.
+
+### Notes
+
+- This is a separate project from the Module Interface.
+- You can develop this project using C# or C++.
+- Set the service icon using the `.rc` file.
+- Set the service name in the `.vcxproj` by setting the `<TargetName>`
+```
+<PropertyGroup>
+  <OutDir>..\..\..\..\$(Platform)\$(Configuration)\$(MSBuildProjectName)\</OutDir>
+  <TargetName>PowerToys.LightSwitchService</TargetName>
+</PropertyGroup>
+```
+- To view the code of the `.vcxproj`, right click the item and select **Unload project**
+- Use the following functions to interact with settings from your service
+```
+ModuleSettings::instance().InitFileWatcher();
+ModuleSettings::instance().LoadSettings();
+auto& settings = ModuleSettings::instance().settings();
+```
+These come from the `ModuleSettings.h` file that lives with the Service. You can copy this from another module (e.g., Light Switch) and adjust to fit your needs.
+
+If your module has a user interface:
+- Use the **WinUI Blank App** template when setting up your project
+- Use [Windows design best practices](https://learn.microsoft.com/windows/apps/design/basics/)
+- Use the [WinUI 3 Gallery](https://apps.microsoft.com/detail/9p3jfpwwdzrc) for help with your UI code, and additional guidance.
+
+## 5. Settings integration
+
+PowerToys settings are stored per-module as JSON under:
+
+```
+%LOCALAPPDATA%\Microsoft\PowerToys\<module>\settings.json
+```
+
+### Implementation steps
+
+- In `src\settings-ui\Settings.UI.Library\` create `<module>Properties.cs` and `<module>Settings.cs`
+- `<module>Properties.cs` is where you will define your defaults. Every setting needs to be represented here. This should match what was set in the Module Interface.
+- `<module>Settings.cs`is where your settings.json will be built from. The structure should match the following
+```cs
+public ModuleSettings()
+{
+    Name = ModuleName;
+    Version = Assembly.GetExecutingAssembly().GetName().Version.ToString();
+    Properties = new ModuleProperties(); // settings properties you set above.
+}
+```
+
+- In `src\settings-ui\Settings.UI\ViewModels` create `<module>ViewModel.cs` this is where the interaction happens between your settings page in the PowerToys app and the settings file that is stored on the device. Changes here will trigger the settings watcher via a `NotifyPropertyChanged` event.
+- Create a `SettingsPage.xaml` at `src\settings-ui\Settings.UI\SettingsXAML\Views`. This will be the page where the user interacts with the settings of your module.
+- Be sure to use resource strings for user facing strings so they can be localized. (`x:Uid` connects to Resources.resw)
+```xaml
+// LightSwitch.xaml
+<ComboBoxItem
+    x:Uid="LightSwitch_ModeOff"
+    AutomationProperties.AutomationId="OffCBItem_LightSwitch"
+    Tag="Off" />
+
+// Resources.resw
+<data name="LightSwitch_ModeOff.Content" xml:space="preserve">
+  <value>Off</value>
+</data>
+```
+> [!IMPORTANT]
+> In the above example we use `.Content` to target the content of the Combobox. This can change per UI element (e.g., `.Text`, `.Header`, etc.)
+
+> **Reminder:** Manual changes via external editors (VS Code, Notepad) do **not** trigger the settings watcher. Only changes written through PowerToys trigger reloads.
+
+---
+
+### Gotchas:
+
+- Only use the WinUI 3 framework, _not_ UWP.
+- Use [`DispatcherQueue`](https://learn.microsoft.com/windows/apps/develop/dispatcherqueue) when updating UI from non-UI threads.
+
+---
+## 6. Building and debugging
+
+### Debugging steps
+
+1. If this is your first time debugging PowerToys, be sure to follow [these steps first](https://github.com/microsoft/PowerToys/blob/main/doc/devdocs/development/debugging.md#pre-debugging-setup).
+2. Set "runner" as the start up project and ensure your build configuration is set to match your system (ARM64/x64)
+3. Select <kbd>F5</kbd> or the **Local Windows Debugger** button to begin debugging. This should start the PowerToys runner.
+4. To set breakpoints in your service, select Ctrl+Alt+P and search for your service to attach to the runner.
+5. Use logs to document changes. The logs live at `%LOCALAPPDATA%\Microsoft\PowerToys\RunnerLogs` and `%LOCALAPPDATA%\Microsoft\PowerToys\Module\Service\<version>` for the specific module.
+
+> [!TIP]
+> PowerToys caches `.nuget` artifacts aggressively. Use `git clean -xfd` when builds behave unexpectedly.
+
+---
+## 7. Installer and packaging (WiX)
+
+### Add your module to installer
+
+1. Install [`WixToolset.Heat`](https://www.nuget.org/packages/WixToolset.Heat/) for Wix5 via nuget
+2. Inside `installer\PowerToysInstallerVNext` add a new file for your module: `Module.wxs`
+3. Inside of this file you will need copy the format from another module (ie: Light Switch) and replace the strings and GUID values.
+4. The key part will be `<!--ModuleNameFiles_Component_Def-->` which is a placeholder for code that will be generated by `generateFileComponents.ps1`.
+5. Inside `Product.wxs` add a line item in the `<Feature Id="CoreFeature" ... >` section. It will look like a list of ` <ComponentGroupRef Id="ModuleComponentGroup" />` items.
+6. Inside `generateFileComponents.ps1` you will need to add an entry to the bottom for your new module. It will follow the following format. `-fileListName <Module>Files` will match the string you set in `Module.wxs`, `<ModuleServiceName>` will match the name of your exe.
+```bash
+# Module Name
+Generate-FileList -fileDepsJson "" -fileListName <Module>Files -wxsFilePath $PSScriptRoot\<Module>.wxs -depsPath "$PSScriptRoot..\..\..\$platform\Release\<ModuleServiceName>"
+Generate-FileComponents -fileListName "<Module>Files" -wxsFilePath $PSScriptRoot\<Module>.wxs -regroot $registryroot
+```
+---
+## 8. Testing and validation
+
+### UI tests
+
+- Place under `/modules/<YourModule>/Tests`
+- Create a new [WinUI Unit Test App](https://learn.microsoft.com/windows/apps/winui/winui3/testing/create-winui-unit-test-project)
+- Write unit tests following the format from previous modules (ie: Light Switch). This can be to test your standalone UI (if you're a module like Color Picker) or to verify that the Settings UI in the PowerToys app is controlling your service.
+
+### Manual validation
+
+- Enable/disable in PowerToys Settings
+- Check initialization in logs
+- Confirm icons, tooltips, and OOBE page appear correctly
+
+### Pro tips
+
+1. Validate wake/sleep and elevation states. Background modules often fail silently after resume if event handles aren’t recreated.
+2. Use Windows Sandbox to simulate clean install environments
+3. To simulate a "new user" you can delete the PowerToys folder from `%LOCALAPPDATA%\Microsoft`
+
+### Shortcut conflict detection
+
+If your module has a shortcut, ensure that it is properly registered following [the steps listed in the documentation](https://github.com/microsoft/PowerToys/blob/main/doc/devdocs/core/settings/settings-implementation.md#shortcut-conflict-detection) for conflict detection.
+
+---
+## 9. The final touches
+
+### Out-of-Box experience (OOBE) page
+
+The OOBE page is a custom settings page that gives the user at a glance information about each module. This window opens before the Settings application for new users and after updates. Create `OOBE<ModuleName>.xaml` at `src\settings-ui\Settings.UI\SettingsXAML\OOBE\Views`. You will also need to add your module name to the enum at `src\settings-ui\Settings.UI\OOBE\Enums\PowerToysModules.cs`.
+
+### Module assets
+
+Now that your PowerToy is _done_ you can start to think about the assets that will represent your module.
+- Module Icon: This will be displayed in a number of places: OOBE page, in the README, on the home screen of PowerToys, on your individual module settings page, etc.  
+- Module Image: This is the image you see at the top of each individual settings page.
+- OOBE Image: This is the header you see on the OOBE page for each module

+> This step is something that the Design team will handle internally to ensure consistency throughout the application. If you have ideas or recommendations on what the icon or screenshots should be for your module feel free to leave it in the "Additional Comments" section of the PR and the team will take it into consideration.
+
+### Documentation
+
+There are two types of documentation that will be required when submitting a new PowerToy:
+1. Developer documentation: This will live in the [PowerToys repo](https://github.com/microsoft/PowerToys/blob/main/doc/devdocs/modules) at `/doc/devdocs/modules/` and should tell a developer how to work on your app. It should outline the module architecture, key files, testing, and tips on debugging if necessary.
+2. Microsoft Learn documentation: When your new Module is ready to be merged into the PowerToys repository, an internal team member will create Microsoft Learn documentation so that users will understand how to use your module. There is not much work on your end as the developer for this step, but keep an eye on your PR in case we need more information about your PowerToy for this step.
+

+Thank you again for contributing! If you need help, feel free to [open an issue](https://github.com/microsoft/PowerToys/issues/new/choose) and use the `Needs-Team-Response` label so we know you need attention.

 TODO: Add implementation details
 
+### Paste with AI Preview
+
+The "Show preview" setting (`ShowCustomPreview`) controls whether AI-generated results are displayed in a preview window before pasting. **The preview feature does not consume additional AI credits**—the preview displays the same AI response that was already generated, cached locally from a single API call.
+
+The implementation flow:
+1. User initiates "Paste with AI" action
+2. A single AI API call is made via `ExecutePasteFormatAsync`
+3. The result is cached in `GeneratedResponses`
+4. If preview is enabled, the cached result is displayed in the preview UI
+5. User can paste the cached result without any additional API calls
+
+See the `ExecutePasteFormatAsync(PasteFormat, PasteActionSource)` method in `OptionsViewModel.cs` for the implementation.
+
 ## Debugging
 
 TODO: Add debugging information
 
 ## Settings
 
-TODO: Add settings documentation
+| Setting | Description |
+|---------|-------------|
+| `ShowCustomPreview` | When enabled, shows AI-generated results in a preview window before pasting. Does not affect AI credit consumption. |

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
