-# 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
-
-.EXAMPLE
-    # Fix single issue in current repo (no worktree)
-    ./Start-IssueAutoFix.ps1 -IssueNumber 12345 -SkipWorktree
-
-.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
-    - Fix agent invoked in 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.

-- Decision owners/acceptance signals: **≤15**
-
-## Effort
-Days + **T-shirt** (XS 0.5–1d, S 1–2, M 2–4, L 4–7, XL 7–14, XXL 14–30, Epic >30).  
-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
-## Suggested Actions

-# 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.

-
-.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

-
-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
-```

-## 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

-# 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.

-- **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).

-
-## 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)

-.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

-# Submit PR Skill
-
-Commit changes from issue worktrees and create pull requests with AI-generated titles and descriptions following PowerToys conventions.
-
-## Skill Contents
-
-This skill is **self-contained** with all required resources:
-
-```
-.github/skills/submit-pr/
-├── SKILL.md              # This file
-├── LICENSE.txt           # MIT License
-├── scripts/
-│   └── Submit-IssueFixes.ps1    # Main submit script
-└── references/
-    ├── create-commit-title.prompt.md  # Commit title rules
-    └── create-pr-summary.prompt.md    # PR description template
-```
-
-## Output
-
-PRs are created on GitHub with:
-- Conventional commit title (e.g., `fix(fancyzones): resolve editor crash on multi-monitor`)
-- Description following `.github/pull_request_template.md`
-- Auto-linked to the original issue via `Fixes #{{IssueNumber}}`
-
-## When to Use This Skill
-
-- Create a PR for a fixed issue
-- Commit and push changes from a worktree
-- Submit changes after using `issue-fix` skill
-- Generate PR title and description
-- Finalize an issue fix with a pull request
-
-## Prerequisites
-
-- GitHub CLI (`gh`) installed and authenticated
-- Changes made in an issue worktree (from `issue-fix` skill)
-- PowerShell 7+ for running scripts
-
-## Required Variables
-
-| Variable | Description | Example |
-|----------|-------------|---------|
-| `{{IssueNumber}}` | Issue number(s) to submit | `44044` or `44044, 32950` |
-
-## Workflow
-
-### Step 1: Verify Changes Exist
-
-Check that the worktree has uncommitted or unpushed changes:
-
-```powershell
-# List issue worktrees
-git worktree list | Select-String "issue/"
-
-# Check status in a worktree
-cd Q:/PowerToys-xxxx
-git status
-```
-
-### Step 2: Submit PR
-
-Execute the submit script (use paths relative to this skill folder):
-
-```powershell
-# From repo root
-.github/skills/submit-pr/scripts/Submit-IssueFixes.ps1 -IssueNumbers {{IssueNumber}} -CLIType copilot
-```
-
-This will:
-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.

+# MCCS Capabilities String Parser - Recursive Descent Design
+
+## Overview
+
+This document describes the recursive descent parser implementation for DDC/CI MCCS (Monitor Control Command Set) capabilities strings.
+
+### Attention!
+This document and the code implement are generated by Copilot.
+
+## Grammar Definition (BNF)
+
+```bnf
+capabilities      ::= ['('] segment* [')']
+segment           ::= identifier '(' segment_content ')'
+segment_content   ::= text | vcp_entries | hex_list
+vcp_entries       ::= vcp_entry*
+vcp_entry         ::= hex_byte [ '(' hex_list ')' ]
+hex_list          ::= hex_byte*
+hex_byte          ::= [0-9A-Fa-f]{2}
+identifier        ::= [a-z_A-Z]+
+text              ::= [^()]+
+```
+
+## Example Input
+
+```
+(prot(monitor)type(lcd)model(PD3220U)cmds(01 02 03 07)vcp(10 12 14(04 05 06) 16 60(11 12 0F) DC DF)mccs_ver(2.2)vcpname(F0(Custom Setting)))
+```
+
+## Parser Architecture
+
+### Component Hierarchy
+
+```
+MccsCapabilitiesParser (main parser)
+├── ParseCapabilities()      → MccsParseResult
+├── ParseSegment()           → ParsedSegment?
+├── ParseBalancedContent()   → string
+├── ParseIdentifier()        → ReadOnlySpan<char>
+├── ApplySegment()           → void
+│   ├── ParseHexList()       → List<byte>
+│   ├── ParseVcpEntries()    → Dictionary<byte, VcpCodeInfo>
+│   └── ParseVcpNames()      → void
+│
+├── VcpEntryParser (sub-parser for vcp() content)
+│   └── TryParseEntry()      → VcpEntry
+│
+├── VcpNameParser (sub-parser for vcpname() content)
+│   └── TryParseEntry()      → (byte code, string name)
+│
+└── WindowParser (sub-parser for windowN() content)
+    ├── Parse()              → WindowCapability
+    └── ParseSubSegment()    → (name, content)?
+```
+
+### Design Principles
+
+1. **ref struct for Zero Allocation**
+   - Main parser uses `ref struct` to avoid heap allocation
+   - Works with `ReadOnlySpan<char>` for efficient string slicing
+   - No intermediate string allocations during parsing
+
+2. **Recursive Descent Pattern**
+   - Each grammar rule has a corresponding parse method
+   - Methods call each other recursively for nested structures
+   - Single-character lookahead via `Peek()`
+
+3. **Error Recovery**
+   - Errors are accumulated, not thrown
+   - Parser attempts to continue after errors
+   - Returns partial results when possible
+
+4. **Sub-parsers for Specialized Content**
+   - `VcpEntryParser` for VCP code entries
+   - `VcpNameParser` for custom VCP names
+   - Each sub-parser handles its own grammar subset
+
+## Parse Methods Detail
+
+### ParseCapabilities()
+Entry point. Handles optional outer parentheses and iterates through segments.
+
+```csharp
+private MccsParseResult ParseCapabilities()
+{
+    // Handle optional outer parens
+    // while (!IsAtEnd()) { ParseSegment() }
+    // Return result with accumulated errors
+}
+```
+
+### ParseSegment()
+Parses a single `identifier(content)` segment.
+
+```csharp
+private ParsedSegment? ParseSegment()
+{
+    // 1. ParseIdentifier()
+    // 2. Expect '('
+    // 3. ParseBalancedContent()
+    // 4. Expect ')'
+}
+```
+
+### ParseBalancedContent()
+Extracts content between balanced parentheses, handling nested parens.
+
+```csharp
+private string ParseBalancedContent()
+{
+    int depth = 1;
+    while (depth > 0) {
+        if (char == '(') depth++;
+        if (char == ')') depth--;
+    }
+}
+```
+
+### ParseVcpEntries()
+Delegates to `VcpEntryParser` for the specialized VCP entry grammar.
+
+```csharp
+vcp_entry ::= hex_byte [ '(' hex_list ')' ]
+
+Examples:
+- "10"           → code=0x10, values=[]
+- "14(04 05 06)" → code=0x14, values=[4, 5, 6]
+- "60(11 12 0F)" → code=0x60, values=[0x11, 0x12, 0x0F]
+```
+
+## Comparison with Other Approaches
+
+| Approach | Pros | Cons |
+|----------|------|------|
+| **Recursive Descent** (this) | Clear structure, handles nesting, extensible | More code |
+| **Regex** (DDCSharp) | Concise | Hard to debug, limited nesting |
+| **Mixed** (original) | Pragmatic | Inconsistent, hard to maintain |
+
+## Performance Characteristics
+
+- **Time Complexity**: O(n) where n = input length
+- **Space Complexity**: O(1) for parsing + O(m) for output where m = number of VCP codes
+- **Allocations**: Minimal - only for output structures
+
+## Supported Segments
+
+| Segment | Description | Parser |
+|---------|-------------|--------|
+| `prot(...)` | Protocol type | Direct assignment |
+| `type(...)` | Display type (lcd/crt) | Direct assignment |
+| `model(...)` | Model name | Direct assignment |
+| `cmds(...)` | Supported commands | ParseHexList |
+| `vcp(...)` | VCP code entries | VcpEntryParser |
+| `mccs_ver(...)` | MCCS version | Direct assignment |
+| `vcpname(...)` | Custom VCP names | VcpNameParser |
+| `windowN(...)` | PIP/PBP window capabilities | WindowParser |
+
+### Window Segment Format
+
+The `windowN` segment (where N is 1, 2, 3, etc.) describes PIP/PBP window capabilities:
+
+```
+window1(type(PIP) area(25 25 1895 1175) max(640 480) min(10 10) window(10))
+```
+
+| Sub-field | Format | Description |
+|-----------|--------|-------------|
+| `type` | `type(PIP)` or `type(PBP)` | Window type (Picture-in-Picture or Picture-by-Picture) |
+| `area` | `area(x1 y1 x2 y2)` | Window area coordinates in pixels |
+| `max` | `max(width height)` | Maximum window dimensions |
+| `min` | `min(width height)` | Minimum window dimensions |
+| `window` | `window(id)` | Window identifier |
+
+All sub-fields are optional; missing fields default to zero values.
+
+## Error Handling
+
+```csharp
+public readonly struct ParseError
+{
+    public int Position { get; }    // Character position
+    public string Message { get; }  // Human-readable error
+}
+
+public sealed class MccsParseResult
+{
+    public VcpCapabilities Capabilities { get; }
+    public IReadOnlyList<ParseError> Errors { get; }
+    public bool HasErrors => Errors.Count > 0;
+    public bool IsValid => !HasErrors && Capabilities.SupportedVcpCodes.Count > 0;
+}
+```
+
+## Usage Example
+
+```csharp
+// Parse capabilities string
+var result = MccsCapabilitiesParser.Parse(capabilitiesString);
+
+if (result.IsValid)
+{
+    var caps = result.Capabilities;
+    Console.WriteLine($"Model: {caps.Model}");
+    Console.WriteLine($"MCCS Version: {caps.MccsVersion}");
+    Console.WriteLine($"VCP Codes: {caps.SupportedVcpCodes.Count}");
+}
+
+if (result.HasErrors)
+{
+    foreach (var error in result.Errors)
+    {
+        Console.WriteLine($"Parse error at {error.Position}: {error.Message}");
+    }
+}
+```
+
+## Edge Cases Handled
+
+1. **Missing outer parentheses** (Apple Cinema Display)
+2. **No spaces between hex bytes** (`010203` vs `01 02 03`)
+3. **Nested parentheses** in VCP values
+4. **Unknown segments** (logged but not fatal)
+5. **Malformed input** (partial results returned)
