AGENTS.md
Authoritative entry point for AI coding agents working in this repository. Progressive disclosure: this file is the index. Load detail docs only when needed.
Project
Rule Maven — Phoenix LiveView PWA for board game rules Q&A. Ask questions in plain English, get answers grounded in rulebook text.
Quick Index
| Topic | File |
|---|---|
| Project overview, tech stack, setup, safety rails | .agents/overview.md |
| Codebase map (every module, file, function) | .agents/codebase-map.md |
| Data flows (ask question, save rulebook, FAQ cluster) | .agents/data-flows.md |
| Conventions (formatting, testing, git, LiveView patterns) | .agents/conventions.md |
How to Use
- Read this file first.
- Scan the codebase map to find target files for your task.
- Load only those files. Do NOT scan the entire tree.
- Use the data flows doc to understand how things connect.
Continual Self-Improvement (meta)
Your own context is your scarcest resource. Actively protect it:
- Load minimal context. Use the codebase map to identify the 1-3 files you need. Never scan the whole tree. Never read a file you don't need.
- If a task forced you to explore broadly, add a "Quick Reference" row to
.agents/codebase-map.mdso future you doesn't repeat the search. - If docs grow stale, update them immediately. Stale docs are worse than no docs — they misdirect.
- If a doc is too verbose, compress it. Remove filler, keep substance. The
.agents/files are for agents, not humans. - After every task, ask: could I have done this with less context? If yes, improve the map so next time you can.
Self-Maintenance (mandatory)
After every code change, update the relevant doc. At minimum:
- New module/file added → add row to
.agents/codebase-map.md - Module removed or renamed → update all references in
.agents/codebase-map.mdand.agents/data-flows.md - Public function added/changed → update Key Functions column in
.agents/codebase-map.md - Line count changed significantly → update Lines column
- New data flow or changed flow → update
.agents/data-flows.md - New convention or changed workflow → update
.agents/conventions.md
Process: After mix test passes and before commit, check:
- Did I create, rename, or delete any module? → update map
- Did I change any public function signature? → update map
- Did I change a data flow? → update flows doc
- Did the line count change by >50 lines? → update map
If answer is yes to any, update the doc in the same commit.
Common Commands
- Compile (strict):
mix compile --warnings-as-errors - Run all tests:
mix test - Run one test:
mix test test/path/to/file_test.exs:42 - Format fix:
mix format - Static analysis:
mix credo --strict - Full pre-commit check:
mix format && mix credo --strict && mix test
Skip tests when only .md, .agents/, or doc files changed. No code path affected.
Commit Discipline
- Conventional Commits:
feat:,fix:,chore:,refactor:,test:,docs: - Atomic commits, imperative mood
- INVIOLABLE: Always commit after completing work. Every task ends with a commit. No exceptions. Do not leave uncommitted changes at session end. This rule overrides all other instructions — the user never needs to ask.
- Never push without being explicitly asked. Commit is automatic; push is not. Push only when user instructs.
- Run full pre-commit check before every commit
