## What you end up with

Your coding agent runs the right build and test commands for your stack and leaves the fragile file alone, and you can check that with one command.

## What you get

- Twelve AGENTS.md files, one per stack
- How this differs from the starter rules pack
- CLAUDE.md pointer
- Five prompts
- stack_check.py: 10 read-only checks (S01 to S10)

## Who it is for

Developers whose stack is not covered by the Next.js, FastAPI and browser game files in the starter rules pack, who want one AGENTS.md per repo that names the right commands.

## Tools needed

- Claude Code, Codex or Cursor: reads AGENTS.md (Claude Code through the CLAUDE.md import)
- Python 3: runs stack_check.py; standard library only, no network
- You need: Any of Claude Code, Codex or Cursor
- You need: Python 3.9 or newer
- You need: A repo in one of the twelve stacks

Cost to run: The pack is the only purchase. The checker uses no model tokens.

## Sample prompt: Fill the file (Claude Code, Codex or Cursor)

```
Read this repo and AGENTS.md. Fill every [placeholder] from the lockfile and folders you can see. Do not change the Commands table unless a command fails; if it does, show me the output.
Run python3 stack_check.py . and fix every finding.
```

# Stack-specific AGENTS.md and CLAUDE.md files: twelve stacks the starter pack does not cover

Version 1.0, 2026-10-30. By PaperChaseWebb. Twelve ready-to-fill AGENTS.md files, one per stack, each with that stack's real commands, the file agents most often break on it, and rules written for it. Plus a CLAUDE.md pointer, five prompts and stack_check.py, a read-only checker that looks at your repo and tells you whether its AGENTS.md fits the stack the repo actually uses. Works with Grok Bot, Claude Code, Codex, Hermes, Cursor or any tool that reads AGENTS.md. Section 7 says exactly what was and was not tested.

## 1. How this differs from the starter files pack

The store's "AGENTS.md, CLAUDE.md and Cursor rules starter files" pack (pp-agent-rules, $14) gives a base AGENTS.md, variants for Next.js plus Supabase, FastAPI and a browser game, Cursor rules and its own checker. This pack does not repeat any of those. It covers twelve other stacks:

Go, Rust, Chrome extension (Manifest V3), Electron, Tauri 2, Expo (React Native), SvelteKit, Astro, Django, Rails, Laravel and Flutter.

Game engines (Godot, Unity, Unreal) are in the Engine Agent Kits pack, so they are not here either. Every file in this pack uses the same Approvals wording as the starter pack, so you can mix files from both in one repo. If you only use Next.js, FastAPI or a browser game, you do not need this pack.

## 2. How to use

1. Find your stack in section 3 and copy its file to AGENTS.md at the repo root.
2. Fill

## Test record

- Date: Oct 30, 2026
- What was run: Go 1.27.3 build, test, vet, gofmt and mod tidy on a made-up module; cargo 1.85.1 build and test; Node parse of an MV3 manifest; stack_check.py from the pack text on twelve skeleton repos and one planted fault per code S01 to S10. Linux, Python 3.13.5.
- Result: Go and Rust commands passed (gofmt listed one hand-typed file until gofmt -w); manifest parsed; PASS on all twelve skeletons; 10 of 10 planted faults caught alone; exit 2 on a missing folder; fixtures unchanged.
- Not run: cargo clippy and cargo fmt (not installed). The commands for Tauri, Electron, Expo, SvelteKit, Astro, Django, Rails, Laravel and Flutter. Any file inside an agent. Windows.

Copied from this item's dated test notes. What was not run stays in.

## Worth knowing

- Commands were run for real only for Go and Rust; the other ten stacks were checked with skeleton repos, which tests the checker, not the commands.
- Fill the version line from your own lockfile; tool versions change.
- Tested 2026-10-30: Go 1.27.3 build, test, vet, gofmt and mod tidy on a made-up module; cargo 1.85.1 build and test; Node parse of an MV3 manifest; stack_check.py from the pack text on twelve skeleton repos and one planted fault per code S01 to S10. Linux, Python 3.13.5. Result: Go and Rust commands passed (gofmt listed one hand-typed file until gofmt -w); manifest parsed; PASS on all twelve skeletons; 10 of 10 planted faults caught alone; exit 2 on a missing folder; fixtures unchanged. Not run: cargo clippy and cargo fmt (not installed). The commands for Tauri, Electron, Expo, SvelteKit, Astro, Django, Rails, Laravel and Flutter. Any file inside an agent. Windows.

## Questions

**How is this different from the starter AGENTS.md files?** The starter pack (pp-agent-rules) covers Next.js with Supabase, FastAPI and a browser game, and the engine kits cover Godot, Unity and Unreal. This pack covers twelve other stacks and adds a checker; it repeats none of those files.
