Action Summary
This GitHub Action automates static code analysis for TypeScript and JavaScript projects by identifying unused files, circular dependencies, duplication, complexity hotspots, boundary violations, and design-system styling drift. It provides deterministic findings with typed output contracts and can be integrated into CI workflows to ensure code quality before deployment. The action supports various formats and integrates with popular development tools like LSP servers for language-specific analysis.
What’s Changed
Fallow Impact in your status line
fallow impact statusline gives agent and editor chrome one compact, path-free
line with the latest whole-project issue count, its trend, and findings cleared
while Impact was tracking. It reads local history only, never runs analysis,
migrates data, records telemetry, or prints normal CLI notices.
The Fallow plugin for Claude Code can compose this line with an existing status line. Codex and other agents can use the same stable command through the bundled Fallow skill.
Cloud runtime confidence
Cloud never_called evidence now keeps its provenance. Runtime-observed
functions can retain the existing high-confidence deletion recommendation,
while inventory-backed, missing, and future provenance remains conservative.
