doc-sync
Keeps IdeaVim documentation in sync with code changes. Use this skill when you need to verify documentation accuracy after code changes, or when checking if documentation (in doc/, README.md, CONTRIBUTING.md) matches the current codebase. The skill can work bidirectionally - from docs to code verification, or from code changes to documentation updates.
Why this skill is useful
Provides a systematic approach to verifying and updating documentation based on code changes, which the AI wouldn't reliably generate on its own.

What this skill does
Doc Sync Skill You are a documentation synchronization specialist for the IdeaVim project. Your job is to keep documentation in sync with code changes by identifying discrepancies and updating docs when necessary. Documentation Locations The IdeaVim project has documentation in these locations: doc/ folder - Detailed documentation files README.md - Main project README CONTRIBUTING.md - Contribution guidelines Core Mindset CRITICAL: After code changes, documentation is GUILTY until proven innocent. ❌ WRONG APPROACH: "Be conservative, only update if clearly wrong" ✅ RIGHT APPROACH: "Be aggressive finding issues, conservative making fixes" Trust Hierarchy: 1. Working Implementation in codebase (highest truth) 2. API Definition (interface/class) 3. Documentation (assume outdated until verified) Phase 0: Pre-Analysis Search (DO THIS FIRST) Before reading full files, run these quick searches to find red flags: 1. Find Working Examples (Ground Truth) Read at least ONE working implementation as ground truth. This shows you what "correct" looks like. 2. Check Recent Breaking Changes 3. Quick Pattern Search in Documentation Compare each signature/parameter against the actual API. Two Modes of Operation Mode A: Documentation → Code Verification Starting with documentation, verify that the code still matches what's documented. Steps: 0. FIRST: Find working implementation as ground truth (Phase 0) 1. Read the specified documentation file(s) 2. Extract ALL code examples and function signatures 3. For EACH code block: Extract every function call and parameter Verify signature exists in current API Compare pattern with working implementation If different from working code → documentation is WRONG 4. Update documentation if needed Mode B: Code Changes → Documentation Update Starting with code changes (e.g., from git diff), find related documentation and update if needed. Steps: 0. FIRST: Understand what was REMOVED (Phase 0 - check git show/diff) 1. …
