What it does
fallow-skills teaches coding agents to work with fallow, a code analysis layer for TypeScript and JavaScript. The repository holds the fallow, fallow-setup, fallow-review, fallow-cloud-setup and cargo-fallow skills along with plugins for Claude Code, Codex and Cursor. The agent calls fallow through the CLI or MCP and receives reports on quality, impact of changes, circular dependencies, duplicates and what nothing depends on. Install depends on the agent. The universal path is npx skills add fallow-rs/fallow-skills. In Claude Code run /plugin marketplace add fallow-rs/fallow-skills and /plugin install fallow@fallow-skills, in Codex codex plugin marketplace add fallow-rs/fallow-skills and codex plugin add fallow@fallow-skills. For Cursor the manifest is at fallow/.cursor-plugin/plugin.json, the plugin is copied to ~/.cursor/plugins/local/fallow, and Windsurf and Amp have commands with the --agent flag. The plugin adds the Fallow app: an interactive code health dashboard inline in Claude Code and the Code tab of Claude Desktop. The /fallow:analyze command runs the analysis and the Fix with Claude button sends selected findings to the conversation. Codex gets a Code Health tab, @Fallow mentions, a .fallowrc.json editor with an impact preview and a .sarif viewer. For Claude Code there is the Fallow Impact statusline, set up with /fallow:impact-statusline setup user compose.
Who it is for. TypeScript teams that connect fallow to Claude Code, Codex or Cursor and want the agent to call the analysis and apply findings itself.
Good fit when
- fallow is already in the project and the agent needs to be told when and how to call it
- You need a code health dashboard right in Claude Code or Codex that sends findings to the conversation
- Before merging you need to check a branch for new dead exports and cycles through fallow-review
- You want to see the impact of selected findings in the Claude Code statusline
- Cursor, Windsurf or Amp need the same skills: --agent windsurf, --agent amp
Not a fit when
- The project is not JavaScript or TypeScript: fallow analyzes only those
- You need the analyzer itself without skills: npx fallow from the main repository is enough
- The app needs Node.js 20 or newer and it is unavailable
- You need type checking or a linter: fallow looks for unused code and duplicates and does not check style
Example request
Run /fallow:analyze in this repository, show unused exports and circular dependencies and send the selected findings for fixingLimitations
- Fallow must be installed or reachable through npx; the dashboard app needs Node.js 20 or newer and runs the CLI on your machine, so code stays local.
- The .mcpb extension for Claude Desktop and the plugin should be installed one at a time: together they give Claude two sets of Fallow tools.
- In Claude Desktop chat the result arrives as text and is not passed to the dashboard yet.
- The Cursor plugin has no Claude Code commit gate or statusline. Copy the cloned plugin folder whole, since Cursor skips symlinks.
How to disable. In Claude Code remove the plugin with /plugin uninstall fallow@fallow-skills, in Codex remove it through the plugin menu. For skills installed with npx skills add, delete the fallow* folders in the agent skills directory.
FAQ
How do I install fallow-skills in Claude Code?
Run /plugin marketplace add fallow-rs/fallow-skills, then /plugin install fallow@fallow-skills. The skills, the fallow MCP server and the dashboard app appear.
How do I install the skills without the plugin?
Run npx skills add fallow-rs/fallow-skills. For Windsurf and Amp add the --agent flag, and Gemini CLI has gemini skills install.
How does the plugin differ from fallow itself?
fallow analyzes code, while the plugin teaches the agent to call it and shows the result in a dashboard. The analysis runs locally through the CLI on your machine.
Can I install the .mcpb extension together with the plugin?
No, pick one, otherwise Claude sees two sets of Fallow tools. The Claude Desktop extension ships with every release as fallow-app-<version>.mcpb.
How do I install the plugin in Cursor?
Clone the repository and run mkdir -p ~/.cursor/plugins/local and cp -R fallow-skills/fallow ~/.cursor/plugins/local/fallow. Then reload the window with Developer: Reload Window.
