--save-regression-baseline, then fail CI only on newly introduced issues using fallow audit --base <branch> or --fail-on-regression. - Duplication and Complexity Analysis: Detect copy-pasted code with strict-to-semantic clone modes and rank churn-weighted refactoring targets via cyclomatic/cognitive complexity hotspots. - Use Case: Before a refactor of a T3 Turbo monorepo, run fallow dead-code --format json --quiet --changed-workspaces origin/main to scope analysis to changed workspaces, preview removals with fallow fix --dry-run, then apply with fix --yes after user sign-off. ## Quick Start Ask the agent to audit this TypeScript repo for dead code and unused dependencies using fallow with JSON output, then preview safe auto-fixes before applying them.High-intent search queries and answers about installing and using this skill.
Run fallow dead-code with --format json --quiet to get structured findings for unused files, exports, types, and dependencies. In a pnpm or Turbo monorepo, add --workspace or --changed-workspaces origin/main to scope results to affected packages.
Run fallow migrate --dry-run to preview the converted config, then fallow migrate to write .fallowrc.json. It auto-detects knip.json, .jscpd.json, and package.json embedded configs, mapping rules, ignore patterns, and duplication settings.
The fix command requires --yes in non-TTY environments because it normally prompts for confirmation. Always preview with fix --dry-run --format json --quiet first, then apply with fix --yes --format json --quiet.
No, fallow only analyzes TypeScript and JavaScript codebases using Oxc-based syntactic analysis. It is also not a replacement for type checking (tsc), linting (ESLint/Biome), or security scanning.
Save a regression baseline with fallow --save-regression-baseline .fallow/baseline.json and commit it. CI then compares against the snapshot with --fail-on-regression so only newly introduced issues fail the gate, not pre-existing debt.
Exit code 1 means issues were found at error severity, which is the expected result of an audit. Append || true to invocations so shells do not treat it as failure; only exit code 2 indicates a real runtime error.
