+# PR Comment Script Improvements
+
+## Summary of Changes
+
+The `post-ai-summary-comment.ps1` script has been significantly improved to make posting PR review comments easier and more flexible using **dynamic section extraction**.
+
+## Key Improvements
+
+### 1. **Dynamic Section Extraction** (NEW!)
+
+**Before:** Script used hardcoded pattern matching with predefined title variations
+
+**After:** Script **automatically discovers ALL sections** from your state file and extracts them dynamically
+
+```powershell
+# Extracts ALL <details><summary><strong>TITLE</strong></summary> sections
+$allSections = Extract-AllSections -StateContent $Content
+
+# Then maps them to phases using flexible regex patterns
+$preFlightContent = Get-SectionByPattern -Sections $allSections -Patterns @(
+    '📋.*Issue Summary',
+    '📋.*Pre-Flight'
+)
+```
+
+**Benefits:**
+- ✅ **No hardcoded titles** - works with ANY section header you use
+- ✅ **Automatically adapts** - add new sections without modifying the script
+- ✅ **Better debugging** - shows exactly which sections were found
+- ✅ **More maintainable** - less code, more flexible
+
+**Example debug output:**
+```
+[DEBUG] Found 7 section(s) in state file
+[DEBUG] Section: '📋 Issue Summary' (803 chars)
+[DEBUG] Section: '🧪 Tests' (539 chars)
+[DEBUG] Section: '🚦 Gate - Test Verification' (488 chars)
+[DEBUG] Section: '🔧 Fix Candidates' (868 chars)
+[DEBUG] Section: '📋 Final Report' (2351 chars)
+[DEBUG] Matched '📋 Final Report' with pattern '📋.*Report'
+```
+
+---
+
+### 2. **Flexible Pattern Matching**
+
+**Before:** Exact string matching required
+
+**After:** Uses **regex patterns** to match section titles flexibly
+
+```powershell
+# Matches any of these (and more!):
+- "📋 Final Report" ✅
+- "📋 Phase 5: Final Report" ✅
+- "📋 Report - Final Recommendation" ✅
+- Any title containing "📋" and "Report" ✅
+```
+
+**Pattern examples:**
+- `'📋.*Issue Summary'` matches "📋 Issue Summary", "📋 Pre-Flight Issue Summary", etc.
+- `'🧪.*Tests'` matches "🧪 Tests", "🧪 Phase 2: Tests", etc.
+- `'📋.*Report'` matches any title with 📋 and Report in it
+
+---
+
+### 3. **Errors vs Warnings**
+
+**Validation levels:**
+- **Errors** (❌) - Block posting (missing content, PENDING markers)
+- **Warnings** (⚠️) - Suggestions only (missing optional sections)
+
+**Example:**
+```
+✅ All validation checks passed!
+
+⚠️  VALIDATION WARNINGS
+Found 2 warning(s) (non-critical):
+  - Fix: Fix phase missing 'Exhausted' field (non-critical)
+
+💡 These are suggestions but won't block posting.
+```
+
+---
+
+### 4. **Debug Mode**
+
+Enable detailed extraction information:
+
+```powershell
+$DebugPreference = 'Continue'
+./post-ai-summary-comment.ps1 -PRNumber 12345
+```
+
+**Shows:**
+- Which sections were found in the state file
+- How many characters each section contains
+- Which patterns matched which sections
+- Why validation passed or failed
+
+---
+
+### 5. **Better Error Messages**
+
+**Comprehensive guidance when validation fails:**
+```
+⛔ VALIDATION FAILED
+
+💡 Fix these issues in the state file before posting.
+   Or use -SkipValidation to bypass these checks.
+
+🐛 Debug tip: Run with $DebugPreference = 'Continue' for details
+```
+
+---
+
+## How Dynamic Extraction Works
+
+### Step 1: Extract ALL Sections
+
+```powershell
+function Extract-AllSections {
+    # Pattern matches: <details><summary><strong>TITLE</strong></summary>...content...</details>
+    $pattern = '(?s)<details>\s*<summary><strong>([^<]+)</strong></summary>(.*?)</details>'
+    $matches = [regex]::Matches($StateContent, $pattern)
+    
+    # Returns hashtable: @{ "Title" = "content", ... }
+}
+```
+
+**Result:** Hashtable with ALL sections from your state file
+
+### Step 2: Map to Phases
+
+```powershell
+function Get-SectionByPattern {
+    # Try each pattern until one matches
+    foreach ($pattern in $Patterns) {
+        foreach ($key in $Sections.Keys) {
+            if ($key -match $pattern) {
+                return $Sections[$key]  # Found it!
+            }
+        }
+    }
+}
+```
+
+**Result:** Phase content matched by flexible regex patterns
+
+---
+
+## Usage Examples
+
+### Basic Usage (unchanged)
+```powershell
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27340
+```
+
+### With Debug Mode (recommended when troubleshooting)
+```powershell
+pwsh -Command '$DebugPreference = "Continue"; ./.github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27340'
+```
+
+### Skip Validation
+```powershell
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27340 -SkipValidation
+```
+
+### Dry Run
+```powershell
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27340 -DryRun
+```
+
+---
+
+## What Section Headers Work Now?
+
+**The script uses regex patterns, so it's VERY flexible:**
+
+### Pre-Flight Phase
+Any title matching `'📋.*Issue Summary'` or `'📋.*Pre-Flight'`:
+- ✅ "📋 Issue Summary" (preferred)
+- ✅ "📋 Pre-Flight Analysis"
+- ✅ "📋 Context and Issue Summary"
+
+### Tests Phase
+Any title matching `'🧪.*Tests'`:
+- ✅ "🧪 Tests"
+- ✅ "🧪 Phase 2: Tests"
+- ✅ "🧪 Test Verification"
+
+### Gate Phase
+Any title matching `'🚦.*Gate'`:
+- ✅ "🚦 Gate - Test Verification"
+- ✅ "🚦 Gate"
+- ✅ "🚦 Phase 3: Gate"
+
+### Fix Phase
+Any title matching `'🔧.*Fix'`:
+- ✅ "🔧 Fix Candidates"
+- ✅ "🔧 Fix Analysis"
+- ✅ "🔧 Fix"
+
+### Report Phase
+Any title matching `'📋.*Report'` or `'Final Report'`:
+- ✅ "📋 Final Report"
+- ✅ "📋 Phase 5: Report"
+- ✅ "📋 Report - Final Recommendation"
+- ✅ "Final Report"
+
+**The beauty:** You don't need to remember exact titles anymore!
+
+---
+
+## Migration Guide
+
+**No changes needed!** The script is backward compatible.
+
+**Old state files** with exact headers like:
+```markdown
+<summary><strong>📋 Phase 5: Report — Final Recommendation</strong></summary>
+```
+
+**New state files** with simpler headers like:
+```markdown
+<summary><strong>📋 Final Report</strong></summary>
+```
+
+**Both work!** The dynamic extraction finds them automatically.
+
+---
+
+## Advantages Over Old Approach
+
+| Aspect | Old (Pattern Matching) | New (Dynamic Extraction) |
+|--------|------------------------|--------------------------|
+| **Flexibility** | ❌ Hardcoded titles | ✅ Any title works |
+| **Maintenance** | ❌ Update code for new headers | ✅ No code changes needed |
+| **Debugging** | ⚠️ Limited visibility | ✅ Full extraction visibility |
+| **Speed** | ⚠️ Tries multiple patterns | ✅ Single pass extraction |
+| **Reliability** | ⚠️ Can miss variations | ✅ Finds everything |
+
+---
+
+## Common Issues & Solutions
+
+### Issue: "Phase X has NO content in state file"
+
+**Step 1:** Enable debug mode to see what was found
+```powershell
+pwsh -Command '$DebugPreference = "Continue"; ./post-ai-summary-comment.ps1 -PRNumber XXXXX'
+```
+
+**Look for:**
+```
+[DEBUG] Found 7 section(s) in state file
+[DEBUG] Section: 'Your Section Title' (XXX chars)
+```
+
+**Step 2:** Check if your section title matches the patterns
+
+Report phase patterns: `'📋.*Report'`, `'Final Report'`
+
+If your title is `"📋 Final Analysis"`, it won't match!
+
+**Solution:** Either:
+- Rename section to include "Report": `"📋 Final Report"` ✅
+- Or use `-SkipValidation` if content is there
+
+---
+
+### Issue: Section extracted but content is empty
+
+**Cause:** State file structure issue (missing content between tags)
+
+**Check your markdown:**
+```markdown
+<details>
+<summary><strong>📋 Final Report</strong></summary>
+
+<!-- Content MUST be here -->
+Your report content...
+
+</details>
+```
+
+**Not this:**
+```markdown
+<details>
+<summary><strong>📋 Final Report</strong></summary>
+</details>  ❌ No content!
+```
+
+---
+
+## Developer Notes
+
+### How to Add Support for New Phase Patterns
+
+Just add a regex pattern to the mapping:
+
+```powershell
+$reportContent = Get-SectionByPattern -Sections $allSections -Patterns @(
+    '📋.*Report',
+    'Final Report',
+    'Your New Pattern Here'  # Add here
+) -Debug:$debugMode
+```
+
+**Example:** Support "Summary" as alias for "Report":
+```powershell
+$reportContent = Get-SectionByPattern -Sections $allSections -Patterns @(
+    '📋.*Report',
+    '📋.*Summary',  # New pattern
+    'Final Report'
+)
+```
+
+---
+
+### Regex Pattern Tips
+
+- `.*` matches any characters
+- `^` matches start of string
+- `$` matches end of string
+- Use `[regex]::Escape()` if you need literal special chars
+
+**Examples:**
+- `'🧪.*Tests'` - Title must contain both 🧪 and Tests
+- `'^📋 Report'` - Title must START with "📋 Report"
+- `'Report$'` - Title must END with "Report"
+
+---
+
+## Testing
+
+Tested with:
+- ✅ PR #27340 (7 sections extracted successfully)
+- ✅ Debug mode showing section discovery
+- ✅ Various header formats
+- ✅ Dry run mode
+- ✅ Skip validation mode
+- ✅ Empty sections (proper error handling)
+
+**Debug output example:**
+```
+[DEBUG] Found 7 section(s) in state file
+[DEBUG] Section: '📋 Issue Summary' (803 chars)
+[DEBUG] Section: '📁 Files Changed' (0 chars)
+[DEBUG] Section: '💬 PR Discussion Summary' (0 chars)
+[DEBUG] Section: '🧪 Tests' (539 chars)
+[DEBUG] Section: '🚦 Gate - Test Verification' (488 chars)
+[DEBUG] Section: '🔧 Fix Candidates' (868 chars)
+[DEBUG] Section: '📋 Final Report' (2351 chars)
+[DEBUG] Matched '📋 Issue Summary' with pattern '📋.*Issue Summary'
+[DEBUG] Matched '🧪 Tests' with pattern '🧪.*Tests'
+[DEBUG] Matched '🚦 Gate - Test Verification' with pattern '🚦.*Gate'
+[DEBUG] Matched '🔧 Fix Candidates' with pattern '🔧.*Fix'
+[DEBUG] Matched '📋 Final Report' with pattern '📋.*Report'
+```
+
+---
+
+## Future Improvements
+
+Potential enhancements:
+- [ ] Auto-generate comment structure from discovered sections
+- [ ] Support markdown headings (`##`/`###`) as alternative to `<details>`
+- [ ] Validate section content structure (required fields)
+- [ ] Suggest section renaming for better patterns
+- [ ] Export sections as separate files for versioning
+
+---
+
+## Feedback
+
+The dynamic extraction makes the script much more maintainable and flexible!
+
+If you find sections that aren't being extracted:
+1. Run with `$DebugPreference = 'Continue'` to see what was found
+2. Check which patterns are being used
+3. Add a new pattern if needed (or rename your section)
+
+---
+
+### 2. **Errors vs Warnings**
+
+**Before:** Everything was treated as a blocking error
+
+**After:** Two levels of feedback:
+- **Errors** (❌) - Block posting (e.g., missing content, PENDING markers)
+- **Warnings** (⚠️) - Suggestions only (e.g., missing optional sections)
+
+**Example output:**
+```
+✅ All validation checks passed!
+
+⚠️  VALIDATION WARNINGS
+Found 2 warning(s) (non-critical):
+  - Report: Report phase missing root cause analysis (non-critical)
+  - Fix: Fix phase missing 'Exhausted' field (non-critical)
+
+💡 These are suggestions for improvement but won't block posting.
+```
+
+---
+
+### 3. **Debug Mode**
+
+**New feature:** Set `$DebugPreference = 'Continue'` to see detailed extraction information
+
+```powershell
+$DebugPreference = 'Continue'
+./post-ai-summary-comment.ps1 -PRNumber 12345
+```
+
+**Debug output shows:**
+```
+[DEBUG] Matched pattern for: 📋 Final Report
+[DEBUG] Content length: 2355 chars
+[DEBUG] First 100 chars: ---
+
+### Summary
+
+PR #27340 provides a **correct and well-tested fix**...
+```
+
+**Benefit:** Easy troubleshooting when validation fails
+
+---
+
+### 4. **Better Error Messages**
+
+**Before:**
+```
+⛔ VALIDATION FAILED
+Found 1 validation error(s):
+  - Report: Phase Report is marked as '✅ COMPLETE' but has NO content in state file
+```
+
+**After:**
+```
+⛔ VALIDATION FAILED
+Found 1 validation error(s):
+  - Report: Phase Report is marked as '✅ COMPLETE' but has NO content in state file
+
+💡 Fix these issues in the state file before posting the review comment.
+   Or use -SkipValidation to bypass these checks (not recommended).
+
+🐛 Debug tip: Run with $DebugPreference = 'Continue' for detailed extraction info
+```
+
+---
+
+### 5. **Relaxed Phase 5 Validation**
+
+**Before:** Report phase required:
+- Exact "Final Recommendation" text
+- "Root Cause" section
+- "Key Findings" section
+- "Solution Analysis" section
+- Minimum 500 characters
+
+**After:** Report phase only requires:
+- Any form of recommendation (APPROVE, REQUEST CHANGES, etc.)
+- Any form of analysis (Summary, Fix Quality, etc.)
+- Minimum 200 characters (reduced from 500)
+
+**Benefit:** More flexibility in how you structure the final report
+
+---
+
+## Usage Examples
+
+### Basic Usage (unchanged)
+```powershell
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27340
+```
+
+### With Debug Mode
+```powershell
+$DebugPreference = 'Continue'
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27340
+```
+
+### Skip Validation (when needed)
+```powershell
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27340 -SkipValidation
+```
+
+### Dry Run (preview only)
+```powershell
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27340 -DryRun
+```
+
+---
+
+## What You Need to Know
+
+### Headers That Work Now
+
+Any of these variations will be recognized:
+
+**Pre-Flight:**
+- `📋 Issue Summary` ✅ (preferred)
+- `📋 Pre-Flight` ✅
+- `🔍 Pre-Flight` ✅
+
+**Tests:**
+- `🧪 Tests` ✅ (preferred)
+- `📋 Tests` ✅
+
+**Gate:**
+- `🚦 Gate - Test Verification` ✅ (preferred)
+- `🚦 Gate` ✅
+- `📋 Gate` ✅
+
+**Fix:**
+- `🔧 Fix Candidates` ✅ (preferred)
+- `🔧 Fix` ✅
+- `📋 Fix` ✅
+
+**Report:**
+- `📋 Final Report` ✅
+- `📋 Phase 5: Final Report` ✅
+- `📋 Report` ✅
+- `Phase 5: Report` ✅
+- `Final Report` ✅
+
+---
+
+## Migration Guide
+
+**No changes needed!** The script is backward compatible. If you have existing state files with the old header format, they'll continue to work.
+
+If you want to use the new flexibility:
+- Just use simpler headers like `📋 Final Report` instead of `📋 Phase 5: Report — Final Recommendation`
+- The script will find it either way
+
+---
+
+## Common Issues & Solutions
+
+### Issue: "Phase Report has NO content in state file"
+
+**Solution 1:** Check your state file structure
+```bash
+grep -A 5 "📋.*Report" CustomAgentLogsTmp/PRState/pr-XXXXX.md
+```
+
+Make sure you have:
+```markdown
+<details>
+<summary><strong>📋 Final Report</strong></summary>
+
+Your report content here...
+
+</details>
+```
+
+**Solution 2:** Use debug mode to see what's happening
+```powershell
+$DebugPreference = 'Continue'
+./post-ai-summary-comment.ps1 -PRNumber XXXXX
+```
+
+**Solution 3:** Use `-SkipValidation` if content is definitely there
+```powershell
+./post-ai-summary-comment.ps1 -PRNumber XXXXX -SkipValidation
+```
+
+---
+
+### Issue: Validation warnings about missing sections
+
+**These are just suggestions!** Warnings won't block posting. You can:
+- Ignore them (the comment will post anyway)
+- Address them if you want a more complete review
+- Use `-SkipValidation` to hide all validation output
+
+---
+
+## Developer Notes
+
+### How Pattern Matching Works
+
+```powershell
+function Extract-PhaseContent {
+    param(
+        [string]$StateContent,
+        [string[]]$PhaseTitles,  # Array of possible titles
+        [switch]$Debug
+    )
+    
+    foreach ($title in $PhaseTitles) {
+        $pattern = "(?s)<details>\s*<summary><strong>$([regex]::Escape($title))</strong></summary>(.*?)</details>"
+        if ($StateContent -match $pattern) {
+            return $Matches[1].Trim()
+        }
+    }
+    return $null  # No match found
+}
+```
+
+The function tries each pattern in order until one matches.
+
+### Adding New Pattern Variations
+
+To support a new header variation, just add it to the array:
+
+```powershell
+$reportContent = Extract-PhaseContent -StateContent $Content -PhaseTitles @(
+    "📋 Phase 5: Report — Final Recommendation",
+    "📋 Phase 5: Final Report",
+    "📋 Phase 5: Report",
+    "📋 Final Report",
+    "📋 Report",
+    "Phase 5: Report",
+    "Final Report",
+    "Your New Pattern Here"  # <-- Add here
+) -Debug:$debugMode
+```
+
+---
+
+## Future Improvements
+
+Potential enhancements:
+- [ ] Auto-detect phase titles from state file (no hardcoded patterns)
+- [ ] Support markdown headings (`##` / `###`) in addition to `<details>`
+- [ ] Validate links and references work
+- [ ] Check that commit SHAs are valid
+- [ ] Suggest fixes for common issues (auto-fix mode)
+
+---
+
+## Testing
+
+The improvements have been tested with:
+- ✅ PR #27340 (Entry/Editor keyboard issue)
+- ✅ State files with various header formats
+- ✅ Dry run mode
+- ✅ Debug mode
+- ✅ Skip validation mode
+- ✅ Multiple phase title variations
+
+---
+
+## Feedback
+
+If you encounter issues or have suggestions, please:
+1. Try debug mode first: `$DebugPreference = 'Continue'`
+2. Check the state file structure
+3. Report the issue with debug output included

+# Critical Rule: No External File References in PR Comments
+
+## The Problem
+
+When the PR agent posts review comments to GitHub, those comments are viewed by:
+- PR authors
+- Other reviewers  
+- Future contributors searching issue history
+- Community members watching the PR
+
+**None of these people have access to your local files!**
+
+## The Rule
+
+### ❌ NEVER Do This
+
+```markdown
+### Title & Description: ⚠️ Minor Updates Needed
+
+**Issues to fix:**
+1. Missing required NOTE block
+2. Technical inaccuracy in description
+
+**See:** `CustomAgentLogsTmp/PRState/27340/pr-finalize/pr-finalize-summary.md` for recommended updates
+```
+
+**Why this is bad:**
+- GitHub users can't access `CustomAgentLogsTmp/`
+- Makes the review useless - "see file I can't access"
+- Author can't act on recommendations
+- Future agents can't learn from the review
+
+---
+
+### ✅ ALWAYS Do This
+
+```markdown
+### Title & Description: ⚠️ Minor Updates Needed
+
+**Current description is HIGH QUALITY:**
+- ✅ Clear root cause for both platforms
+- ✅ Before/after videos
+- ✅ Well-structured sections
+
+**Issues to fix:**
+
+**Issue 1: Missing required NOTE block**
+
+Add this at the top of the description:
+```markdown
+> [!NOTE]
+> Are you waiting for the changes in this PR to be merged?
+> It would be very helpful if you could [test the resulting artifacts](https://github.com/dotnet/maui/wiki/Testing-PR-Builds) from this PR and let us know in a comment if this change resolves your issue. Thank you!
+```
+
+**Issue 2: Technical inaccuracy in "Description of Change"**
+
+Current text says:
+> "Added platform-specific handling to dismiss the soft keyboard **and remove focus**..."
+
+Should say:
+> "Added platform-specific handling to dismiss the soft keyboard when the Entry or Editor visibility is set to False."
+
+**Reason:** The code only calls `HideSoftInputAsync()` to dismiss the keyboard. It does NOT call `Unfocus()` to remove focus. Focus state remains unchanged.
+
+**Recommended additions:**
+
+Add an **Implementation** subsection:
+```markdown
+**Implementation:**
+- Added `MapIsVisible` handler in `InputView.Platform.cs` (iOS/Android only)
+- Calls `HideSoftInputAsync()` when control becomes invisible and keyboard is showing
+- Registered handler in `Entry.Mapper.cs` and `Editor.Mapper.cs`
+```
+```
+
+**Why this is good:**
+- ✅ Self-contained - everything needed is in the comment
+- ✅ Actionable - author can copy/paste the fixes
+- ✅ Clear - shows exact before/after text
+- ✅ Educational - explains the reasoning
+- ✅ Accessible - works on GitHub
+
+---
+
+## Where This Applies
+
+### pr-finalize Skill
+
+When running `pr-finalize` skill, you create TWO outputs:
+
+1. **Summary file** (local reference)
+   - Location: `CustomAgentLogsTmp/PRState/XXXXX/pr-finalize/pr-finalize-summary.md`
+   - Purpose: Your detailed analysis and working notes
+   - Audience: You and local CLI users
+
+2. **State file Report section** (GitHub audience)
+   - Location: `CustomAgentLogsTmp/PRState/pr-XXXXX.md` (Report phase)
+   - Purpose: Final recommendations that get posted to GitHub
+   - Audience: PR authors, reviewers, community
+   - **MUST be self-contained** - no external references
+
+### PR Agent Phase 5 (Report)
+
+When completing Phase 5:
+- Include ALL pr-finalize findings inline
+- Show exact code blocks for NOTE block
+- Show exact before/after text for corrections
+- Explain reasoning for each recommendation
+- Never reference local files
+
+---
+
+## Examples from Real Usage
+
+### ❌ Bad Example (PR #27340 - first attempt)
+
+```markdown
+**Issues to fix:**
+1. **Missing required NOTE block** (mandatory for all PRs)
+2. **Minor technical inaccuracy:** Description says "remove focus" but code only dismisses keyboard
+
+**See:** `CustomAgentLogsTmp/PRState/27340/pr-finalize/pr-finalize-summary.md` for recommended updates
+```
+
+**Result:** PR author sees the issues but has no idea how to fix them without accessing local files.
+
+---
+
+### ✅ Good Example (PR #27340 - corrected)
+
+```markdown
+**Issues to fix:**
+
+**Issue 1: Missing required NOTE block**
+
+Add this at the top of the description:
+```markdown
+> [!NOTE]
+> Are you waiting for the changes in this PR to be merged?
+> It would be very helpful if you could [test the resulting artifacts](https://github.com/dotnet/maui/wiki/Testing-PR-Builds) from this PR and let us know in a comment if this change resolves your issue. Thank you!
+```
+
+**Issue 2: Technical inaccuracy in "Description of Change"**
+
+Current text says:
+> "Added platform-specific handling to dismiss the soft keyboard **and remove focus**..."
+
+Should say:
+> "Added platform-specific handling to dismiss the soft keyboard when the Entry or Editor visibility is set to False."
+
+**Reason:** The code only calls `HideSoftInputAsync()` to dismiss the keyboard. It does NOT call `Unfocus()` to remove focus.
+
+**Recommended additions to description:**
+
+Add an **Implementation** subsection after "Description of Change":
+```markdown
+**Implementation:**
+- Added `MapIsVisible` handler in `InputView.Platform.cs` (iOS/Android only)
+- Calls `HideSoftInputAsync()` when control becomes invisible and keyboard is showing
+- Registered handler in `Entry.Mapper.cs` and `Editor.Mapper.cs`
+```
+```
+
+**Result:** PR author can immediately act on every recommendation with clear guidance.
+
+---
+
+## Checklist for Report Phase
+
+When completing Phase 5, verify:
+
+- [ ] All recommendations are inline (no file references)
+- [ ] Code blocks show exact text to add
+- [ ] Before/after comparisons for corrections
+- [ ] Reasoning explained for each issue
+- [ ] Examples are copy/paste ready
+- [ ] No references to `CustomAgentLogsTmp/`

+# PR Comment Skill
+
+This skill posts automated progress comments to GitHub Pull Requests during the PR review workflow. Comments are **self-contained** with collapsible Review Session details, providing rich context to maintainers and contributors.
+
+**⚠️ Self-Contained Rule**: All content in PR comments must be self-contained. Never reference local files like `CustomAgentLogsTmp/` - GitHub users cannot access your local filesystem.
+
+**✨ Key Features**:
+- **Single Unified Comment**: ONE comment per PR/Issue containing ALL sections (PR Review, Try-Fix, Write-Tests, Verify-Tests)
+- **Section-Based Updates**: Each script updates only its section, preserving others
+- **Duplicate Prevention**: Finds existing `<!-- AI Summary -->` comment and updates it
+- **File-Based DryRun Preview**: Use `-DryRun` to preview changes in a local file before posting
+- **Auto-Loading State Files**: Automatically finds and loads state files from `CustomAgentLogsTmp/PRState/`
+- **Simple Interface**: Just provide PR number - script handles everything else
+
+## Comment Architecture
+
+### Unified AI Summary Comment
+
+Most scripts post to the **same single comment** identified by `<!-- AI Summary -->`. Each script updates its own section:
+
+```markdown
+<!-- AI Summary -->
+
+## 🤖 AI Summary
+
+<!-- SECTION:PR-REVIEW -->
+... PR review phases ...
+<!-- /SECTION:PR-REVIEW -->
+
+<!-- SECTION:TRY-FIX -->
+... try-fix attempts ...
+<!-- /SECTION:TRY-FIX -->
+
+<!-- SECTION:WRITE-TESTS -->
+... write-tests attempts ...
+<!-- /SECTION:WRITE-TESTS -->
+
+<!-- SECTION:VERIFY-TESTS -->
+... test verification results ...
+<!-- /SECTION:VERIFY-TESTS -->
+```
+
+**Behavior:**
+- First script to run creates the comment
+- Subsequent scripts find the existing comment and update/add their section
+- Sections are independent - updating one preserves others
+
+### Separate PR Finalization Comment
+
+The `post-pr-finalize-comment.ps1` script posts a **separate comment** identified by `<!-- PR-FINALIZE-COMMENT -->`. This is intentional because:
+- Finalization reviews can happen multiple times (after each commit)
+- Each review is numbered (Review 1, Review 2, etc.)
+- Keeps finalization reviews distinct from automated analysis
+
+## Section Scripts
+
+### AI Summary Sections (Unified Comment)
+
+| Section | Script | Location |
+|---------|--------|----------|
+| `PR-REVIEW` | `post-ai-summary-comment.ps1` | `.github/skills/ai-summary-comment/scripts/` |
+| `TRY-FIX` | `post-try-fix-comment.ps1` | `.github/skills/ai-summary-comment/scripts/` |
+| `WRITE-TESTS` | `post-write-tests-comment.ps1` | `.github/skills/ai-summary-comment/scripts/` |
+| `VERIFY-TESTS` | `post-verify-tests-comment.ps1` | `.github/skills/ai-summary-comment/scripts/` |
+
+### Separate Comments
+
+| Comment | Script | Marker |
+|---------|--------|--------|
+| PR Finalization | `post-pr-finalize-comment.ps1` | `<!-- PR-FINALIZE-COMMENT -->` |
+
+## Supported Phases
+
+| Phase | Description | When to Post | What This Enables Next |
+|-------|-------------|--------------|------------------------|
+| `pre-flight` | Context gathering complete | After documenting issue, files, and discussion | **Tests Phase**: Agent can now verify/create test files that reproduce the bug |
+| `tests` | Test analysis complete | After identifying test files and coverage | **Gate Phase**: Agent can run tests to verify they catch the bug |
+| `gate` | Test validation complete | After running tests and verifying bug reproduction | **Fix Phase**: Agent can explore alternative fixes (tests proven to catch bug) |
+| `fix` | Solution comparison complete | After comparing PR fix with alternatives | **Report Phase**: Agent can finalize recommendation based on fix comparison |
+| `report` | Final analysis complete | After generating comprehensive review | **PR Decision**: Maintainers can approve/merge or request changes based on full analysis |
+
+## Usage
+
+### Simplest: Just provide PR number
+
+```bash
+# Auto-loads CustomAgentLogsTmp/PRState/pr-27246.md
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 27246
+```
+
+### With explicit state file path
+
+```bash
+# PRNumber auto-extracted from filename (pr-27246.md → 27246)
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -StateFile CustomAgentLogsTmp/PRState/pr-27246.md
+```
+
+### Legacy: Provide content directly
+
+```bash
+pwsh .github/skills/ai-summary-comment/scripts/post-ai-summary-comment.ps1 -PRNumber 12345 -Content "$(cat CustomAgentLogsTmp/PRState/pr-12345.md)"
+```
+
+### Parameters
+
+| Parameter | Required | Description | Example |
+|-----------|----------|-------------|---------|
+| `PRNumber` | No* | Pull request number | `12345` |
+| `StateFile` | No* | Path to state file (PRNumber auto-extracted from `pr-XXXXX.md` naming) | `CustomAgentLogsTmp/PRState/pr-27246.md` |
+| `Content` | No* | Full state file content (legacy, can be piped via stdin) | Content from state file |
+| `DryRun` | No | Preview changes in local file instead of posting to GitHub | `-DryRun` |
+| `PreviewFile` | No | Path to local preview file for DryRun mode (default: `CustomAgentLogsTmp/PRState/{PRNumber}/ai-summary-comment-preview.md`) | `-PreviewFile ./preview.md` |
+| `SkipValidation` | No | Skip validation checks (not recommended) | `-SkipValidation` |
+
+*At least one of PRNumber, StateFile, or Content is required. The script will:
+- If `-PRNumber` provided: Auto-load `CustomAgentLogsTmp/PRState/pr-{PRNumber}.md`
+- If `-StateFile` provided: Load the file and extract PRNumber from `pr-XXXXX.md` filename
+- If `-Content` provided: Use content directly (legacy, requires `-PRNumber`)
+
+## DryRun Preview Workflow
+
+Use `-DryRun` to preview the combined comment before posting to GitHub. Each script updates the same preview file, mirroring how the actual GitHub comment is updated.
+
+```bash
+# Step 1: Run verify-tests script (creates preview file)
+pwsh .github/skills/ai-summary-comment/scripts/post-verify-tests-comment.ps1 -PRNumber 32891 -DryRun
+
+# Step 2: Run try-fix script (updates same preview file)
+pwsh .github/skills/ai-summary-comment/scripts/post-try-fix-comment.ps1 -IssueNumber 32891 -DryRun
+
+# Step 3: Review the combined preview
+open CustomAgentLogsTmp/PRState/32891/ai-summary-comment-preview.md
+
+# Step 4: Post for real (remove -DryRun)
+pwsh .github/skills/ai-summary-comment/scripts/post-verify-tests-comment.ps1 -PRNumber 32891
+pwsh .github/skills/ai-summary-comment/scripts/post-try-fix-comment.ps1 -IssueNumber 32891
+```
+
+**Key behavior:** The preview file exactly matches what will be posted to GitHub. Multiple scripts accumulate their sections in the same file.
+
+### Section Ordering
+
+Sections appear in the unified comment in this order (based on which scripts run first):
+1. **VERIFY-TESTS** - Test verification results
+2. **TRY-FIX** - Alternative fix exploration attempts
+3. **WRITE-TESTS** - Test writing attempts
+4. **PR-REVIEW** - PR review phases
+
+Each section is wrapped with markers like `<!-- SECTION:TRY-FIX -->` and `<!-- /SECTION:TRY-FIX -->`.
+
+### Cleanup
+
+To reset the preview file for a fresh start:
+```bash
+rm CustomAgentLogsTmp/PRState/{PRNumber}/ai-summary-comment-preview.md
+```
+
+### Prerequisites
+
+Scripts require GitHub CLI authentication:
+```bash
+gh auth status  # Verify authentication before running
+```
+
+## Comment Format
+
+Comments are formatted with:
+- **Phase badge** (🔍 Pre-Flight, 🧪 Tests, 🚦 Gate, 🔧 Fix, 📋 Report)
+- **Status indicator** (✅ Completed, ⚠️ Issues Found)
+- **Expandable review sessions** (each session is a collapsible section)
+- **What's Next** (what phase happens next)
+
+### Review Session Tracking
+
+When the same PR is reviewed multiple times (e.g., after new commits), the script **updates the single aggregated review comment** and adds a new expandable section for each commit-based review session.
+
+### Example Output
+
+```markdown
+## 🔍 Pre-Flight: Context Gathering Complete
+
+✅ **Status**: Phase completed successfully
+
+### Summary
+- **Issue**: #33356 - CollectionView crash on iOS
+- **Platforms Affected**: iOS, MacCatalyst
+- **Files Changed**: 2 implementation files, 1 test file
+- **Discussion**: 3 key reviewer comments identified
+
+### Key Findings
+- Crash occurs when scrolling rapidly with large datasets
+- Existing PR adds null check in ItemsViewController
+- Test coverage includes iOS device test
+
+### Next Steps
+→ **Phase 2: Tests** - Analyzing test files and coverage

+
+## Script Files
+
+- [`post-ai-summary-comment.ps1`](scripts/post-ai-summary-comment.ps1) - Posts or updates the aggregated PR agent review comment
+- [`post-try-fix-comment.ps1`](scripts/post-try-fix-comment.ps1) - Posts or updates try-fix attempts comment
+
+## Try-Fix Comment Script
+
+The `post-try-fix-comment.ps1` script updates the `<!-- SECTION:TRY-FIX -->` section of the unified AI Summary comment. It aggregates all try-fix attempts into collapsible sections. Works for both issues and PRs (GitHub treats PR comments as issue comments).
+
+**✨ Auto-Loading from `CustomAgentLogsTmp`**: The script automatically discovers and aggregates ALL attempt directories from `CustomAgentLogsTmp/PRState/{IssueNumber}/try-fix/`.
+
+### Usage
+
+#### Simplest: Provide attempt directory
+
+```powershell
+# All parameters auto-loaded from directory structure
+pwsh .github/skills/ai-summary-comment/scripts/post-try-fix-comment.ps1 `
+    -TryFixDir CustomAgentLogsTmp/PRState/27246/try-fix/attempt-1
+```
+
+#### Or just provide issue number
+
+```powershell
+# Auto-discovers and posts latest attempt from CustomAgentLogsTmp/PRState/27246/try-fix/
+pwsh .github/skills/ai-summary-comment/scripts/post-try-fix-comment.ps1 -IssueNumber 27246
+```
+
+#### Legacy: Manual parameters
+
+```powershell
+pwsh .github/skills/ai-summary-comment/scripts/post-try-fix-comment.ps1 `

+.SYNOPSIS
+    Posts or updates a try-fix attempts comment on a GitHub Issue or Pull Request.
+
+.DESCRIPTION
+    Creates ONE comment for all try-fix attempts with each attempt in a collapsible section.
+    Uses HTML marker <!-- TRY-FIX-COMMENT --> for identification.
+    
+    If an existing try-fix comment exists, it will be EDITED with the new attempt added.
+    Otherwise, a new comment will be created.
+    
+    **NEW: Auto-loads from CustomAgentLogsTmp/PRState/{PRNumber}/try-fix/**
+    
+    Format:
+    ## 🔧 Try-Fix Analysis for Issue #XXXXX
+    <!-- TRY-FIX-COMMENT -->
+    
+    <details>
+    <summary><b>Attempt 1: Approach Name ✅ PASS</b></summary>
+
+    ... attempt details ...
+    </details>
+    
+    <details>
+    <summary><b>Attempt 2: Different Approach ❌ FAIL</b></summary>
+
+    ... attempt details ...

-## 🚨 MANDATORY: Save Summary File
-
-**This is NOT optional. Complete this step EVERY time you run this skill.**
-
-Before presenting results to the user, you MUST save the summary:
-
-```bash
-# Create directory
-mkdir -p CustomAgentLogsTmp/PRState/<PRNumber>/pr-finalize
-
-# Save summary to: CustomAgentLogsTmp/PRState/<PRNumber>/pr-finalize/pr-finalize-summary.md
-```
-
-**The summary file must include:**
-- PR number, title, author, date reviewed
-- Verdict (✅ No Changes Needed / ⚠️ Needs Updates)
-- Title assessment (current vs recommended)
-- Description quality assessment with table
-- Issues found table
-- Changed files coverage
-- Recommended description (if changes needed)
-- Action items checklist
-
-**Why this matters:** Skills are complete workflows, not just reference material. Saving the summary ensures:
-1. Traceability of what was reviewed
-2. User can reference findings later
-3. Consistent output format across runs
-

 ## Core Principle: Preserve Quality
 
 **Review existing description BEFORE suggesting changes.** Many PR authors write excellent, detailed descriptions. Your job is to:
