Update Documentation

Automatically synchronize project documentation between the various documentation files.

Sync Rules

Source	Section	Targets
CLAUDE.md	Tech Stack	README.md, docs/index.md
CLAUDE.md	Development Commands	README.md, docs/development/local-setup.md
CLAUDE.md	Project Structure	README.md
README.md	Quick Start	docs/getting-started/quickstart.md

Principle: CLAUDE.md is the technical source of truth; README.md is the user-facing entry document.

Workflow

1. Run Analysis

First check the current sync status:

cd ${PROJECT_ROOT} && python ${SKILL_DIR}/scripts/main.py --analyze

2. Interpret Output

The script displays:

• Synchronized: sections are identical
• Outdated: target differs from source
• Missing: section does not exist

3. Synchronize When Differences Are Found

If differences were found:

cd ${PROJECT_ROOT} && python ${SKILL_DIR}/scripts/main.py --sync

4. Review Results

After synchronization:

• Check the updated files for correct formatting
• Ensure no context-specific adjustments were lost
• If needed: manual post-processing for target-specific phrasing

5. Output Summary

Provide the user with a brief summary:

Documentation synchronized

Updated:
  - README.md: Tech Stack, Development
  - docs/index.md: Tech Stack

Unchanged:
  - docs/getting-started/quickstart.md

Customize Configuration

The sync rules are defined in ${SKILL_DIR}/config/sync_rules.json.

Add a new rule:

{
  "id": "new-rule",
  "source": {"file": "SOURCE.md", "section": "Section Name"},
  "targets": [
    {"file": "TARGET.md", "section": "Target Section"}
  ]
}

Notes

• No automatic commits: The skill only modifies files, it does not commit
• Whitespace-tolerant: Minor formatting differences are ignored
• Section matching: Case-insensitive heading search
• Backup: Create manually before synchronization if needed
