# rulesync-feature-research Maps rulesync features against coding-agent docs: what is supported, where the gaps are, how clients differ. - skill · `type=skill` · Claude Code, Codex, Cursor, GitHub Copilot, Gemini CLI, OpenCode · ★ 1552 - Author: dyoshikawa - License: MIT · policy=mirror · the beginning of the file is at the end of this page - Source: https://github.com/dyoshikawa/rulesync/tree/HEAD/.rulesync/skills/rulesync-feature-research/SKILL.md - Updated: 2026-10-24 - HTML: https://affpapa.org/en/nevibecode/skills/rulesync-feature-research ## What it does The skill builds a reproducible map between a coding-agent client, its upstream docs and the local rulesync implementation. Ask about feature support or triage an issue and you get a table with feature, agent surface, rulesync support, rulesync surface and difference columns. Features with sub-surfaces such as hook events, MCP transports, permission actions, config keys or output roots get a second table. Inside there is a request target table: for each client (`claudecode`, `codexcli`, `cursor`, `copilot`, `geminicli`, `opencode` and others) the skill reads its own file under `references/`. A target without a matching file is treated as coming, not unsupported. For an unknown target it falls back to `references/rulesync-source-map.md` plus the closest existing client map. Support labels follow the README style: `project`, `global`, `simulated`, `unsupported`. Validation runs through dry-run: `pnpm run dev generate --targets --features "*" --dry-run`. The skill advises an all-feature dry-run for a single client by default, and an all-target run for cross-client questions. Dry-run is validation, not the answer. The output ends with a `## Capability Gaps` section that lists only material gaps: unsupported upstream capabilities, lossy import or export, deprecated surfaces. Tests, fixtures and refactors stay out of that list. ## Install ### Claude Code (native platform) 1. **Skills CLI (Vercel)** ```bash npx skills add dyoshikawa/rulesync --skill rulesync-feature-research -a claude-code ``` 2. **Manually: put the files in place** - File: `~/.claude/skills/rulesync-feature-research/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/rulesync-feature-research/ ### Codex 1. **Skills CLI (Vercel)** ```bash npx skills add dyoshikawa/rulesync --skill rulesync-feature-research -a codex ``` 2. **Manually: put the files in place** - File: `.agents/skills/rulesync-feature-research/SKILL.md` — For all projects use ~/.agents/skills/ ### Cursor 1. **Skills CLI (Vercel)** ```bash npx skills add dyoshikawa/rulesync --skill rulesync-feature-research -a cursor ``` 2. **Manually: put the files in place** - File: `.cursor/skills/rulesync-feature-research/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/ ### GitHub Copilot 1. **GitHub CLI** ```bash gh skill install dyoshikawa/rulesync rulesync-feature-research ``` 2. **Manually: put the files in place** - File: `.github/skills/rulesync-feature-research/SKILL.md` ### Gemini CLI 1. **Skills CLI (Vercel)** ```bash npx skills add dyoshikawa/rulesync --skill rulesync-feature-research -a gemini-cli ``` 2. **Platform CLI** ```bash gemini skills install https://github.com/dyoshikawa/rulesync --path .rulesync/skills/rulesync-feature-research ``` ### Windsurf (Devin Desktop) **Manually: put the files in place** - File: `.devin/skills/rulesync-feature-research/SKILL.md` — The legacy .windsurf/skills/ path still works ### OpenCode **Skills CLI (Vercel)** ```bash npx skills add dyoshikawa/rulesync --skill rulesync-feature-research -a opencode ``` ### Claude.ai **Claude.ai** - Zip the folder and upload it in Settings → Capabilities → Skills Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dyoshikawa/rulesync/tree/HEAD/.rulesync/skills/rulesync-feature-research/SKILL.md ## When to use it - check rulesync feature support against client docs - triage an issue where agent behavior and rulesync diverge - build a capability map for a new coding-agent client - find missing project and global scope support - verify generator gates and output roots from dry-run ## Example prompts - Check hook support in cursor against the official docs and rulesync - Build a feature map for codexcli and list the capability gaps - Triage this issue: why is the feature marked simulated in claudecode ## Source text · SKILL.md · MIT Below is the content of a third-party file.
