The previous post covered how we structured the codebase: Effect conventions, ast-grep enforcement, Drift, and CLAUDE.md to collaborate with Claude Code. You describe what you want, review the output, iterate. That works well. This post is about what happens when you step away entirely: giving the agent a list of issues and letting it work through them while you do something else. In autonomous mode, there's no mid-session correction. Anything the enforcement layer doesn't catch compounds across commits which is why clean issue tracking, issue review and end-of-session QA matter more, not less.

static-analysis

fallow
Codebase intelligence for TypeScript and JavaScript. Free static analysis of code and styles: unused code, duplication, circular deps, complexity hotspots, architecture boundaries, design-system drift. Optional paid runtime layer (Fallow Runtime): hot-path review and cold-path deletion evidence from real production traffic.

mago
Mago is a toolchain for PHP that aims to provide a set of tools to help developers write better code.
Mago does the same for PHP now, running a linter, a formatter, and a static analyzer in one Rust binary fast enough to run on every keystroke.

Project mention: Stop shipping apps that crash on a missing env var — introducing envalign | dev.to | 2026-07-20
Format linters like dotenv-linter are great for spacing and ordering. Secret scanners like gitleaks watch history. Neither answers the question "is this project’s env story actually consistent right now?"
-
Before fixing anything, it helps to know exactly what's broken. There's a great tool for this called syncpack. It scans all your package.json files and reports version inconsistencies across the monorepo.
