Fallow Skills
Agent skills that teach AI coding tools to run Fallow for dead code & duplication analysis
Fallow Skills is the missing manual for AI coding agents on TS/JS projects. It turns vague agent guesses into correct Fallow command execution, preventing mishaps like auto-fix without dry-run. If you use Claude Code, Cursor, or similar agents and care about codebase health, install this alongside the CLI. It's free, open-source, and directly addresses the gap between knowing commands and knowing how to apply them correctly.

About Fallow Skills
Fallow Skills is a free, open-source package that installs structured workflows into AI coding agents like Claude Code, Cursor, Windsurf, Gemini CLI, Codex, and Copilot. It teaches agents how to run Fallow CLI commands for dead code detection, code duplication, circular dependency analysis, complexity hotspots, architecture boundary violations, and auto-fix, including correct flag usage and output interpretation. The skills cover CI pipelines, monorepo analysis, migration from knip or jscpd, and incremental adoption. Unlike generic agent knowledge, Fallow Skills provides precise, versioned instructions that avoid common pitfalls like running `fix --yes` in a non-TTY context. It works alongside the Fallow CLI and MCP integration, enabling natural language requests to be translated into reliable, multi-step analysis workflows. For developers already using Fallow, this package bridges the gap between manual CLI expertise and agent autonomy. It is designed for TypeScript/JavaScript codebases and requires the Fallow CLI to be installed separately. The package adheres to the open Agent Skills specification, so it works with any compatible agent. Installation is a one-line command for popular agents, and once installed, agents can handle requests like "Find all unused exports" or "Set up a CI gate" without fetching docs. The skills also include a self-contained adoption prompt for agents that don't support skills or MCP. Compared to relying on generic LLM knowledge, Fallow Skills reduces guesswork and prevents costly misapplications, making it a practical choice for teams standardizing code quality checks across AI-assisted workflows.
Behind the Verdict
We've all seen AI agents confidently run the wrong command or skip a dry-run before a destructive fix. Fallow Skills exists to stamp out exactly that on TypeScript and JavaScript codebases. When you pair it with the Fallow CLI, your agent stops guessing and starts executing the right command with the right flags, then interpreting the output correctly. That's a real workflow improvement, not a gimmick. Pick this up if you already use Fallow or are adopting it, and you rely on agents like Claude Code, Cursor, or Windsurf daily. The one-line setup is painless, and the skills cover everything from dead code detection to CI gate creation using GitHub Actions or GitLab CI. It's especially valuable for teams migrating from knip or jscpd, since the bundled workflows guide the agent through the transition. But skip it if you're a pure CLI purist — if you never hand the wheel to an agent, the skills add nothing. Also, Fallow only analyzes TypeScript and JavaScript, so this won't help with polyglot repos. And if you need live, in-editor diagnostics while you type, you're better served by the VS Code extension than by agent skills. The closest alternative is just letting your agent read the Fallow docs on its own. That works poorly: agents fetch outdated pages, misinterpret flags, and miss gotchas like `fix --yes` failing in non-TTY environments. Fallow Skills removes that failure mode by shipping curated, versioned instructions. It's not a skill for every project, but for teams standardizing code quality on TS/JS with AI-assisted workflows, it's worth the five-minute install.

Real-world workflow fit
Concrete scenarios for the personas Fallow Skills actually fits — and what changes day-one when you adopt it.
Wants to find and remove unused exports quickly.
Outcome: Installs the skill, then asks 'Find all unused exports'—the agent runs fallow dead-code and summarizes findings for cleanup.
Wants to set up a PR gate that blocks dead code above a threshold.
Outcome: Uses the skill to have the agent generate a GitHub Actions workflow with baselines, saving setup time and ensuring correct configuration.
Has an existing knip config and wants to switch smoothly.
Outcome: Follows the migration guide in the skill, letting the agent convert the config and run the first analysis with correct flags.
Use Cases
- Ask your agent to find all unused exports in a project with a single natural language request.
- Identify duplicate code blocks and let the agent refactor them using clone family analysis.
- Detect circular dependencies in a monorepo and get auto-fix suggestions.
- Set up a CI pipeline that gates PRs on dead code thresholds using the agent-generated workflow.
- Migrate an existing knip configuration to Fallow with step-by-step agent guidance.
- Analyze complexity hotspots and architecture boundary violations during code review.
Limitations
- The agent skills require the Fallow CLI to be installed and configured separately, as they provide guidance rather than the tool itself.
- Accuracy depends on the agent's ability to follow the structured workflows, and edge cases may still lead to errors.
- These skills are designed for codebase analysis in TypeScript and JavaScript projects.
