Documentation Consistency Skill

This skill ensures project documentation accurately reflects the current implementation.

When to Use This Skill

• After implementing a new feature
• After fixing a bug that changes behavior
• Before creating a release
• When adding or modifying configuration options
• When adding or modifying keyboard shortcuts
• When updating architecture or patterns
• When reviewing documentation quality

Documentation Update Workflow

1. Identify Changed Components

After code changes, determine which documentation needs updates:

Change Type	Documents to Update
New feature	README.md, CHANGELOG.md
Bug fix	CHANGELOG.md
Config change	README.md (Configuration), CHANGELOG.md
Shortcut change	README.md (Keyboard Shortcuts), CHANGELOG.md
Architecture change	CLAUDE.md, possibly domain CLAUDE.md files
WebView change	src/webview/CLAUDE.md, CLAUDE.md
Test pattern change	src/test/CLAUDE.md

2. Update Documentation in Order

1. CHANGELOG.md - Always update first

   • Add entry under [Unreleased] section
   • Use correct section (Added/Changed/Fixed/etc.)
   • Include issue/PR number if applicable

2. README.md - If user-visible changes

   • Features table if new feature
   • Configuration section if settings changed
   • Keyboard Shortcuts if bindings changed

3. CLAUDE.md - If development process affected

   • Commands section if new npm scripts
   • Architecture section if patterns changed
   • Guidelines if best practices updated

4. Domain-specific docs - If specialized area changed

   • src/webview/CLAUDE.md for WebView changes
   • src/test/CLAUDE.md for testing changes

3. Verify Consistency

Run verification checks from references/verification-checklist.md:

# Version check
node -p "require('./package.json').version"

# Commands check
node -p "require('./package.json').contributes.commands.map(c => c.command).join('\n')"

# Config check
node -p "Object.keys(require('./package.json').contributes.configuration.properties).join('\n')"

Pre-Release Documentation Checklist

Before each release, verify:

• CHANGELOG.md has entry for new version with correct date
• All new features documented in README.md
• All changed configurations documented correctly
• All keyboard shortcuts documented with correct platforms
• Version numbers consistent across files
• No TODO items left in documentation
• Links are working

Quick Reference Commands

Check Undocumented Commands

node -e "
const pkg = require('./package.json');
const fs = require('fs');
const readme = fs.readFileSync('README.md', 'utf8');
pkg.contributes.commands.forEach(cmd => {
  const shortName = cmd.command.replace('secondaryTerminal.', '');
  if (!readme.includes(shortName)) {
    console.log('Undocumented:', cmd.command);
  }
});
"

Check Undocumented Configs

node -e "
const pkg = require('./package.json');
const fs = require('fs');
const readme = fs.readFileSync('README.md', 'utf8');
Object.keys(pkg.contributes.configuration.properties).forEach(key => {
  if (!readme.includes(key)) {
    console.log('Undocumented config:', key);
  }
});
"

Check CHANGELOG Version

VERSION=$(node -p "require('./package.json').version")
grep -q "## \[$VERSION\]" CHANGELOG.md && echo "Version documented" || echo "Version missing in CHANGELOG"

Common Issues and Solutions

Issue: Feature in code but not documented

Solution:

1. Add feature description to README.md Key Features table
2. Add CHANGELOG.md entry under appropriate section
3. If architecture changed, update CLAUDE.md

Issue: Configuration default changed

Solution:

1. Update README.md Configuration section
2. Add CHANGELOG.md entry under Changed
3. Verify package.json description matches

Issue: Keyboard shortcut modified

Solution:

1. Update README.md Keyboard Shortcuts table
2. Include both Mac and Win/Linux bindings
3. Add CHANGELOG.md entry

Issue: Japanese docs out of sync

Solution:

1. Compare README.md with docs/README_ja.md
2. Update Japanese version with new content
3. Consider whether domain CLAUDE.md files should be translated

Writing Style Quick Reference

• Concise: Users skim documentation
• Accurate: Match current implementation exactly
• User-centric: Focus on "how to use" not "how it works"
• Consistent: Follow existing patterns in each file
• Actionable: Include commands and examples
