fallow

# Fallow: codebase intelligence for TypeScript and JavaScript Codebase intelligence for TypeScript and JavaScript. The static layer analyzes code and styles and reports quality, changed-code risk, cleanup opportunities, circular dependencies, code duplication, complexity hotspots, architecture boundary violations, design-system styling drift, feature flag patterns, and opt-in security candidates. Runtime coverage merges production execution data into the same `fallow health` report for hot-path review, cold-path deletion confidence, and stale-flag evidence, with a single local capture available by default and continuous/cloud runtime monitoring available as an optional mode. 123 framework plugins, zero configuration, sub-second static analysis. ## When to Use - Find cleanup opportunities: unused files, exports, types, members, dependencies, or stale flags. - Detect code duplication, circular dependencies, architecture boundary issues, and complexity hotspots. - Check styling consistency, CSS dead surface, and design-token drift. - Audit changed code before a commit, PR, release, or refactor. - Set up CI quality gates, duplication thresholds, and regression baselines. - Auto-fix supported unused exports and dependencies after `--dry-run`. - Investigate why a specific export, dependency, file, or issue type was reported. - Surface local security candidates for an agent to verify (`fallow security`). - Find untested but runtime-reachable code (`fallow health --coverage-gaps`)....
