+.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 Model
+    Copilot CLI model to use (e.g., gpt-5.2-codex).
+
+.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

+
+.PARAMETER CLIType
+    AI CLI to use: copilot or claude. Default: copilot.
+
+.PARAMETER Model
+    Copilot CLI model to use (e.g., gpt-5.2-codex).
+
+.PARAMETER WorktreePath
+    Path to the worktree containing the PR branch. Auto-detected if not specified.
+
+.PARAMETER DryRun
+    Show what would be done without executing.
+
+.PARAMETER Force

+Step prompt files are loaded **only when that step is executed** to minimize context usage:
+- Read `references/review-pr.prompt.md` first for orchestration
+- Load each `references/0X-*.prompt.md` only when executing that step
+- Skip steps based on smart filtering (see review-pr.prompt.md)
+
+### Mandatory External Reference Research
+**Each step prompt includes an `## External references (MUST research)` section.** Before completing any step, you **MUST**:
+
+1. **Fetch the referenced URLs** using `fetch_webpage` or equivalent
+2. **Analyze PR changes against those authoritative sources**
+3. **Include a `## References consulted` section** in the output file listing:
+   - Which guidelines were checked
+   - Any violations found with specific IDs (e.g., WCAG 1.4.3, OWASP A03, CWE-79)
+
+| Step | Key External References |
+|------|------------------------|
+| 04 Accessibility | WCAG 2.1, Windows Accessibility Guidelines |
+| 05 Security | OWASP Top 10, CWE Top 25, Microsoft SDL |
+| 06 Localization | .NET Localization, Microsoft Style Guide |
+| 07 Globalization | Unicode TR9 (BiDi), ICU Guidelines |
+| 09 SOLID Design | .NET Architecture Guidelines, Design Patterns |
+
+**Failure to research external references is a review quality violation.**

+
+## 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
+
+⚠️ **For single PR review**, confirm `{{PRNumber}}` with the user. For batch modes, see "Batch Review Modes" below.
+
+| Variable | Description | Example |
+|----------|-------------|---------|
+| `{{PRNumber}}` | Pull request number to review | `45234` |
+
+## Workflow
+
+### Single PR Review
+
+Execute the review workflow for a specific PR:
+
+```powershell
+# From repo root
+.github/skills/pr-review/scripts/Start-PRReviewWorkflow.ps1 -PRNumbers {{PRNumber}} -CLIType copilot -SkipAssign -SkipFix -Force
+```
+
+### Batch Review Modes
+
+Review multiple PRs with a single command:
+
+```powershell
+# Review ALL open non-draft PRs in the repository
+.github/skills/pr-review/scripts/Start-PRReviewWorkflow.ps1 -AllOpen -SkipAssign -SkipFix -Force
+
+# Review only PRs assigned to me
+.github/skills/pr-review/scripts/Start-PRReviewWorkflow.ps1 -Assigned -SkipAssign -SkipFix -Force
+
+# Review ALL open PRs, skip those already reviewed
+.github/skills/pr-review/scripts/Start-PRReviewWorkflow.ps1 -AllOpen -SkipExisting -SkipAssign -SkipFix -Force
+
+# Limit batch size
+.github/skills/pr-review/scripts/Start-PRReviewWorkflow.ps1 -AllOpen -Limit 50 -SkipExisting -Force
+```
+
+### Background Batch Review (Recommended for Large Batches)
+
+For reviewing many PRs, generate a standalone batch script and run it in background:
+
+```powershell
+# Step 1: Generate the batch script
+.github/skills/pr-review/scripts/Start-PRReviewWorkflow.ps1 -AllOpen -SkipExisting -GenerateBatchScript -Force
+
+# Step 2: Run in background (minimized window)
+Start-Process pwsh -ArgumentList '-File', 'Generated Files/prReview/_batch-review.ps1' -WindowStyle Minimized
+
+# Or run interactively to see progress
+pwsh -File "Generated Files/prReview/_batch-review.ps1"
+```
+
+The batch script:
+- Processes PRs sequentially (more reliable than parallel)
+- Skips already-reviewed PRs automatically
+- Shows progress as `[N/Total] PR #XXXXX`
+- Logs copilot output to `_copilot.log` in each PR folder
+- Reports failed PRs at the end
+
+### 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 |
+| `-AllOpen` | Review ALL open non-draft PRs | `false` |
+| `-Assigned` | Review PRs assigned to current user | `false` |
+| `-Limit` | Max PRs to fetch for batch modes | `100` |
+| `-SkipExisting` | Skip PRs with completed reviews | `false` |
+| `-GenerateBatchScript` | Generate standalone script for background execution | `false` |
+| `-CLIType` | AI CLI to use: `copilot` or `claude` | `copilot` |
+| `-Model` | Copilot model (e.g., `gpt-5.2-codex`) | (optional) |
+| `-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 fix step (recommended - use `pr-fix` skill instead) | `false` |
+| `-MaxParallel` | Maximum parallel jobs | `3` |
+| `-Force` | Skip confirmation prompts | `false` |
+
+**Note**: The `-SkipFix` option is kept for backward compatibility. For fixing PR comments, use the dedicated `pr-fix` skill which provides better control over the fix/resolve loop.
+
+## AI Prompt References
+
+### Orchestration (load first)
+- `references/review-pr.prompt.md` - Main orchestration with PR selection, iteration management, smart filtering
+
+### Step Prompts (load on-demand per step)
+Each step prompt contains:
+- Detailed checklist of concerns (15-25 items)
+- PowerToys-specific checks
+- Severity guidelines
+- Output file template
+- **External references (MUST research)** section
+
+| Step | Prompt File | External References |
+|------|-------------|---------------------|
+| 01 | `01-functionality.prompt.md` | C# Guidelines, .NET API Design |
+| 02 | `02-compatibility.prompt.md` | Windows Versions, .NET Breaking Changes |
+| 03 | `03-performance.prompt.md` | .NET Performance, Async Best Practices |
+| 04 | `04-accessibility.prompt.md` | **WCAG 2.1**, Windows Accessibility |
+| 05 | `05-security.prompt.md` | **OWASP Top 10**, **CWE Top 25**, SDL |
+| 06 | `06-localization.prompt.md` | .NET Localization, MS Style Guide |
+| 07 | `07-globalization.prompt.md` | Unicode BiDi, ICU, Date/Time Formatting |
+| 08 | `08-extensibility.prompt.md` | Plugin Architecture, SemVer |
+| 09 | `09-solid-design.prompt.md` | SOLID Principles, Clean Architecture |
+| 10 | `10-repo-patterns.prompt.md` | PowerToys docs (architecture, style, logging) |
+| 11 | `11-docs-automation.prompt.md` | MS Writing Style, XML Docs |
+| 12 | `12-code-comments.prompt.md` | XML Documentation, Comment Conventions |
+| 13 | `13-copilot-guidance.prompt.md` | Agent Skills Spec, Prompt Engineering |
+
+### Fix Prompt
+- `references/fix-pr-active-comments.prompt.md` - Address active review comments
+
+## Troubleshooting
+
+| Problem | Solution |
+|---------|----------|
+| PR not found | Verify PR number: `gh pr view {{PRNumber}}` |
+| Review incomplete | Check `_copilot-review.log` for errors |
+| Comments not posted | Use VS Code MCP tools (Copilot CLI is read-only) |
+| Missing `## References consulted` | Re-run step with external reference research |
+| Cannot resolve comments | Use `gh api graphql` with resolveReviewThread mutation |
+
+## ⚠️ VS Code Agent Operations
+
+**Copilot CLI's MCP is read-only.** These operations require VS Code MCP tools:
+
+| Operation | VS Code MCP Tool |
+|-----------|------------------|
+| Assign Copilot reviewer | `mcp_github_request_copilot_review` |
+| Post review comments | `mcp_github_pull_request_review_write` |
+| Add line-specific comments | `mcp_github_add_comment_to_pending_review` |
+| Resolve threads | `gh api graphql` with `resolveReviewThread` |
+
+### Resolve Review Thread Example
+
+```powershell
+# Get unresolved threads
+gh api graphql -f query='
+  query {
+    repository(owner: "microsoft", name: "PowerToys") {
+      pullRequest(number: {{PRNumber}}) {
+        reviewThreads(first: 50) {
+          nodes { id isResolved path line }
+        }
+      }
+    }
+  }
+' --jq '.data.repository.pullRequest.reviewThreads.nodes[] | select(.isResolved == false)'
+
+# Resolve a specific thread
+gh api graphql -f query='
+  mutation {
+    resolveReviewThread(input: {threadId: "{{threadId}}"}) {
+      thread { isResolved }
+    }
+  }
+'
+```

+.SYNOPSIS
+    Review and fix PRs in parallel using GitHub Copilot and MCP.
+
+.DESCRIPTION
+    For each PR (from worktrees, specified, or fetched from repo), runs:
+    1. Assigns GitHub Copilot as reviewer via GitHub MCP
+    2. Runs review-pr.prompt.md to generate review and post comments
+    3. Runs fix-pr-active-comments.prompt.md to fix issues
+
+.PARAMETER PRNumbers
