+name: Todo Tracker
+description: Scans TODOs, creates GitHub issues, updates inline references
+---
+
+Scan code for TODO comments. Create GitHub issues. Update TODOs with issue numbers inline. Post or update a single comment with results.
+
+## Workflow
+
+**CRITICAL: Push commits to the PR's existing branch, never create new branches.**
+
+### 1. Scan for TODOs
+
+Search all files in PR changes for TODO comments:
+
+- `// TODO: description`
+- `# TODO: description`
+- `/* TODO: description */`
+- `<!-- TODO: description -->`
+
+**Skip TODOs that already have issue numbers**: `// TODO(#123): description`
+
+Capture for each TODO:
+
+- File path
+- Line number
+- Full description
+- Comment style
+- Indentation level
+
+### 2. Create GitHub Issues
+
+For each TODO without an issue number:
+
+**Issue Title**: First line of TODO description (max 80 chars)
+
+**Issue Body**:
+
+```markdown
+**TODO found in PR #{pr_number}**
+
+{full_description}
+
+**Location**: `{file_path}:{line_number}`
+
+**Context**:
+```{language}
+{3 lines before}
+{TODO line}
+{3 lines after}
+
+```
+
+```
+
+**Labels**: `tech-debt`, `automated`
+
+**Get the issue number** from API response.
+
+### 3. Update TODOs Inline
+For each created issue, update the source file:
+
+**Before**: `// TODO: Fix input validation`
+**After**: `// TODO(#456): Fix input validation`
+
+Rules:
+- Preserve original comment style (`//`, `#`, `/* */`, `<!--`)
+- Maintain indentation
+- Keep description unchanged
+- Insert issue number as `(#{number})`
+
+### 4. Commit Changes
+
+Message format:
+
+```
+
+chore: link TODOs to GitHub issues
+
+- Created {count} issues for tech debt tracking
+- Updated TODO comments with issue numbers
+
+Automated tech debt tracker.
+
+```
+
+### 5. Post or Update Comment
+
+**BEFORE posting, check for existing comments:**
+1. Search PR comments for one containing the marker: `<!-- tech-debt-tracker -->`
+2. If found → **UPDATE** that comment with new results
+3. If not found → **CREATE** new comment
+
+**Comment template:**
+```markdown
+<!-- tech-debt-tracker -->
+## 📋 Tech Debt Tracking Results
+
+**Scanned**: {file_count} files from PR changes
+**TODOs Found**: {total_count}
+**Issues Created**: {new_issue_count}
+
+| File | Line | Issue | Description |
+|------|------|-------|-------------|
+| `{path}` | {line} | [#{number}]({url}) | {description} |
+
+{if issues created:}
+### Changes Made
+- Created {count} GitHub issues
+- Updated {count} TODO comments with issue numbers
+- Commit: {commit_sha}
+
+{if skipped:}
+### Already Tracked
+{count} TODOs already have issue numbers
+
+---
+*Automated tech debt tracker • Last updated: {timestamp}*
+
+```
+
+**The HTML comment `<!-- tech-debt-tracker -->` MUST be the first line for detection to work.**
+
+## Comment Style Mapping
+
+**C/C++/Java/JavaScript**: `// TODO(#123): description`**Python/Ruby/Shell**: `# TODO(#123): description`**CSS/C block**: `/* TODO(#123): description */`**HTML/XML**: `<!-- TODO(#123): description -->`
+
+## Rules
+
+- Only process files changed in the PR
+- Never modify TODOs that already have issue numbers
+- Preserve all formatting except the issue number insertion
+- If no TODOs found, exit without commenting
+- If GitHub API fails, post comment with error details for manual review
+- **ALWAYS check for existing comment before posting. Editing exiting comments**
+
+## Edge Cases
+
+- No TODOs detected → Exit without commenting
+- All TODOs already tracked → Comment showing existing issues
+- API rate limit → Post comment suggesting retry later
+- File encoding issues → Skip file and note in comment
+- Existing tracker comment → Update it, don't create new one
