Documentation Sync Check Skill

Checklist for ensuring documentation stays synchronized with code changes.

When to use this skill

Use this skill when changes affect:

• User-visible behavior or features
• API contracts or endpoints
• Configuration options or environment variables
• Deployment or installation procedures
• Developer workflows or contribution processes
• Build or validation processes

Core Principle

Documentation must be updated in the same PR as the code change. Outdated docs are a maintenance burden and user pain point.

Prerequisites

Before running this checklist:

1. Identify which documentation files might be affected
2. Read AGENTS.md section "Documentation expectations"
3. Review CONTRIBUTING.md for documentation standards

Quick Reference: Which Docs to Update

Change Type	Docs to Check
User-facing feature	README.md + .zh-CN.md, docs/features/*.md + .zh-CN.md
Configuration option	docs/configuration.md + .zh-CN.md, example configs
Installation/deployment	docs/installation.md + .zh-CN.md, skill-sublinkpro/reference/deploy.md
API endpoint	skill-sublinkpro/reference/api.md
Developer workflow	docs/development.md + .zh-CN.md, CONTRIBUTING.md + .zh-CN.md
Architecture/guidelines	AGENTS.md
New documentation	skill-sublinkpro/reference/docs.md (documentation map)

Bilingual Documentation Checklist

For every documentation change:

Both languages

• Updated English canonical file (.md)
• Updated Chinese translation file (.zh-CN.md)
• Content semantically equivalent (not just machine-translated)
• Examples work in both language contexts

Language switches

• Language switch links at top of document work
• Links use correct format: English | [简体中文](filename.zh-CN.md)
• Chinese version links back: [English](filename.md) | 简体中文

Internal links

• Relative links work in both language files
• Cross-references point to correct language variants
• No broken links in either version

Documentation Map Updates

When documentation structure changes:

Adding new docs

• Added new doc path to skill-sublinkpro/reference/docs.md
• Added description/topic in the documentation map
• Added both English and Chinese variants to map

Renaming/moving docs

• Updated path in skill-sublinkpro/reference/docs.md
• Updated all references in other docs
• Verified old paths return 404 (on GitHub)

Removing docs

• Removed from skill-sublinkpro/reference/docs.md
• Checked for incoming links from other docs
• Redirected or updated incoming links

Code Examples in Documentation

When documenting code:

Accuracy

• Code examples actually work
• Commands match what exists in repo
• File paths are correct
• Configuration examples are valid

Completeness

• Required context is provided
• Output examples are realistic
• Error handling shown where relevant

Maintenance

• Examples use current API
• Examples use current configuration format
• Examples reflect current project structure

Verification Checklist

Before committing:

Link checking

• All internal links work (test by clicking in preview)
• No broken references to code files
• No references to removed/renamed files
• Language switch links work

Formatting

• Markdown renders correctly
• Code blocks have correct syntax highlighting
• Tables render properly
• Lists and indentation correct

Consistency

• Both language versions have same structure
• Terminology consistent across docs
• Examples match actual codebase
• Commands match repo's actual commands

When Only Documentation Changed

Pure documentation commits:

No build required

• ✅ No need to run yarn run lint or yarn run build
• ✅ No need to run Go validation

Manual verification required

• Links work
• Both languages updated
• Command examples accurate
• No conflicts with AGENTS.md cross-layer rules

Documentation Anti-Patterns

Avoid these common mistakes:

• ❌ Documenting commands that don't exist (yarn test when no test script)
• ❌ Only updating English docs
• ❌ Describing old behavior after code changed
• ❌ Copy-pasting from generic templates without adapting
• ❌ Leaving broken links
• ❌ Documenting "future features" not yet implemented
• ❌ Outdated screenshots showing old UI

Delivery Requirements

Before marking documentation changes complete:

1. Bilingual verification: Both .md and .zh-CN.md updated
2. Link verification: All links tested and working
3. Accuracy verification: Examples/commands tested
4. Consistency verification: No conflicts with code behavior

Exit Criteria

✅ Can exit when:

• All affected documentation files updated
• Both English and Chinese versions synchronized
• Links verified
• Examples tested
• Code behavior matches documentation

❌ Cannot exit when:

• Only one language updated
• Documentation still describes old behavior
• Broken links remain
• Examples are inaccurate
• New documentation not added to map
