# Anthropic Docs Updater

## Overview

anthropic-docs-updater automatically keeps the anthropic-expert skill current by detecting, fetching, and integrating Anthropic documentation updates.

**Purpose**: Automated documentation maintenance for anthropic-expert

**Update Workflow** (5 steps):
1. **Check for Updates** - Detect new releases and documentation changes
2. **Fetch Documentation** - Download updated content from official sources
3. **Process Content** - Convert to skill reference format
4. **Update Skill** - Integrate new content into anthropic-expert
5. **Validate Updates** - Ensure quality maintained, no regressions

**Automation**: 80% automated (manual review for breaking changes)

**Update Sources**:
- GitHub Releases (SDK version updates)
- docs.claude.com/en/release-notes (API updates)
- code.claude.com/docs/en/changelog (Claude Code updates)
- anthropic.com/news (model announcements)

## When to Use

- Weekly/monthly update checks (stay current)

## Prerequisites

- anthropic-expert skill installed
- Python 3.7+ with requests library
- GitHub API access (for release checking)
- Internet access (for fetching docs)

## Update Workflow

### Step 1: Check for Updates

**Purpose**: Detect new releases, documentation changes, feature announcements

**Process**:

1. **Check GitHub Releases**
   ```bash
   python scripts/check-updates.py --github
   ```
   - Queries GitHub API for latest releases
   - Checks: anthropic-sdk-python, claude-agent-sdk-python
   - Compares to current versions in changelog.md
   - Reports new releases found

2. **Check Release Notes**
   ```bash
   python scripts/check-updates.py --docs
   ```
   - Fetches docs.claude.com/en/release-notes
   - Compares to last check date
   - Identifies new entries

3. **Check Claude Code Changelog**
   ```bash
   python scripts/check-updates.py --claude-code
   ```
   - Fetches code.claude.com/docs/en/changelog
   - Detects new versions or features

4. **Generate Update Report**
   ```bash
   python scripts/check-updates.py --all
   ```
   - Runs all checks
   - Aggregates findings
   - Outputs: update-report.txt with detected changes

**Validation**:
- [ ] GitHub releases checked
- [ ] Release notes checked
- [ ] Claude Code changelog checked
- [ ] Update report generated
- [ ] New updates detected (or confirmed current)

**Outputs**:

   - Structures by product

2. **Convert to Reference Format**
   - Organize by product/capability
   - Format consistently with existing references
   - Extract code examples properly
   - Add navigation headers

3. **Merge with Existing Content**
   - Compare new vs existing documentation
   - Identify additions, changes, removals
   - Preserve custom examples/notes
   - Generate diff report

4. **Validate Processed Content**

### Step 5: Validate Updates

**Purpose**: Ensure updates maintain quality and don't introduce regressions

**Process**:

1. **Run Structure Validation**
   ```bash
   python ../../review-multi/scripts/validate-structure.py ../anthropic-expert
   ```
   - Validates YAML frontmatter
   - Checks file structure
   - Verifies naming conventions
   - Ensures progressive disclosure
   - Must pass (5/5 or 4/5)

2. **Test Search Functionality**
   ```bash
   python ../anthropic-expert/scripts/search-docs.py "test query"
   ```
   - Verify search still works
   - Check can find content in updated files
   - Ensure no search errors

3. **Manual Spot Check**
   - Review 2-3 updated sections
   - Verify accuracy of new content
   - Check code examples valid
   - Ensure formatting consistent

4. **Validation Decision**
   - **PASS**: All validations successful → Finalize update
   - **FAIL**: Issues found → Rollback and investigate

5. **Rollback if Failed** (if validation fails)
   ```bash
   python scripts/update-skill.py --rollback
   ```
   - Restores from backup
   - Reverts to previous version
   - Logs failure for investigation

**Validation**:
- [ ] Structure validation passes (≥4/5)
- [ ] Search functionality works
- [ ] Spot check confirms accuracy
- [ ] No regressions detected
- [ ] Quality maintained
- [ ] Update finalized OR rolled back if issues

**Outputs**:
- Validation report
- Final updated skill (if passed)
- OR restored backup (if failed)
- Update success/failure status

**Time Estimate**: 20-30 minutes

## Post-Workflow: Update Complete

**If Successful**:
1. ✅ anthropic-expert updated with latest documentation
2. ✅ Changelog.md updated with changes
3. ✅ Quality validated (structure 5/5)
4. ✅ Ready to use with latest Anthropic features

**If Failed**:
1. ❌ Updates rolled back
2. 📋 Investigation needed (check logs)
3. 🔄 Manual review of changes
4. 🛠️ Fix issues and retry

**Next Check**: Weekly or when Anthropic announces updates

---

## Best Practices

### 1. Schedule Regular Updates
**Practice**: Weekly automated check for updates

**Implementation**: Cron job or scheduled task
```bash
# Weekly check (Mondays at 9am)
0 9 * * 1 cd /path/to/skills && python anthropic-docs-updater/scripts/check-updates.py --all
```

### 2. Review Breaking Changes Manually
**Practice**: For major version updates, review changes before applying

**Why**: Breaking changes may require manual updates to examples

### 3. Backup Before Updating
**Practice**: Always backup (Step 4 does this automatically)

**Why**: Can rollback if updates cause issues

### 4. Validate After Updates
**Practice**: Always run Step 5 (validation)

**Why**: Ensures updates don't break skill quality

### 5. Track Update History
**Practice**: Maintain detailed changelog

**Why**: Understand what changed when, aids troubleshooting

| 3. Process Content | Convert format | 20-40m | 90% | processed/docs/ |
| 4. Update Skill | Integrate content | 15-30m | 95% | Updated skill |
| 5. Validate | Ensure quality | 20-30m | 70% | Validation report |

**Total Time**: 1.5-2.5 hours (mostly automated)

### Update Sources

| Source | What It Tracks | Check Method |
|--------|----------------|--------------|
| GitHub Releases | SDK versions | GitHub API |
| Release Notes | API features | Web scraping |
| Claude Code Changelog | CLI updates | Web scraping |
| Anthropic News | Model announcements | Manual/RSS |

### Common Commands

```bash
