Sync RSPress Documentation with API Changes

Syncs RSPress site documentation with changes in auto-generated API docs.

Overview

This skill detects API changes and updates user-facing documentation by:

1. Comparing API doc timestamps with user doc timestamps
2. Identifying stale documentation
3. Updating cross-references
4. Updating code examples
5. Adding migration notes for breaking changes
6. Preserving custom content

Quick Start

Sync all documentation for a module:

/rspress-sync effect-type-registry

Check what needs syncing (dry run):

/rspress-sync rspress-plugin-api-extractor --check-only

Force sync all docs:

/rspress-sync website --force

How It Works

1. Parse Parameters

• module: Module name from design.config.json [REQUIRED]
• --check-only: Report what needs syncing without writing (optional)
• --force: Sync all docs regardless of timestamps (optional)
• --breaking: Add breaking change notes (optional)

2. Load Configuration

Reads design.config.json to find:

• Site docs path
• API docs location
• Module package name

3. Detect API Changes

Compares timestamps:

• Get modification times of all API docs ({siteDocs}/api/**/*.md)
• Get modification times of all user docs ({siteDocs}/**/*.mdx)
• Identify user docs older than latest API changes

4. Analyze Impact

For each changed API doc:

• Parse API doc to understand what changed
• Identify which user docs reference this API
• Determine if changes are breaking or non-breaking
• Collect affected code examples

5. Update Cross-References

Fix broken or outdated links:

• Update paths if API docs moved
• Fix renamed classes/functions/interfaces
• Update anchors if heading structure changed
• Remove references to deleted APIs

6. Update Code Examples

Refresh Twoslash code blocks:

• Update imports if package exports changed
• Fix type signatures if APIs changed
• Add new parameters if required
• Remove deprecated usage patterns

7. Add Migration Notes

For breaking changes:

• Insert callout with migration instructions
• Show before/after code examples
• Link to changelog or release notes
• Highlight deprecated alternatives

8. Preserve Custom Content

Protect user additions:

• Keep custom sections
• Preserve added examples
• Maintain editorial content
• Only update generated portions

9. Generate Sync Report

Creates report with:

• Files updated
• Changes made
• Migration notes added
• Remaining manual updates needed

Sync Strategies

Non-Breaking Changes

For minor API updates:

• Update code examples silently
• Fix cross-references
• No migration notes needed

Breaking Changes

For major API changes:

• Add prominent callout
• Include before/after examples
• Link to migration guide
• Mark deprecated patterns

New APIs

For new functionality:

• Consider adding new guide pages
• Add examples to existing pages
• Update landing page features
• Refresh table of contents

Removed APIs

For deleted functionality:

• Remove or mark as removed
• Add deprecation notice
• Suggest alternatives
• Link to migration path

Supporting Documentation

• instructions.md - Detailed sync process
• examples.md - Sample sync operations

Success Criteria

• ✅ Stale docs identified correctly
• ✅ Cross-references updated
• ✅ Code examples compile
• ✅ Migration notes added for breaking changes
• ✅ Custom content preserved
• ✅ Sync report generated

Integration Points

• Uses .claude/design/design.config.json
• Reads API docs from {siteDocs}/api/
• Updates user docs in {siteDocs}/
• Reads rspress.config.ts for context
