debug-agent AGENTS.md

Project-specific coding and testing rules for a TypeScript repository, including file naming, type usage, command conventions, comments, and required checks.

In plain words
What is it for?
Use them when editing TypeScript code, installing dependencies, running scripts, naming files, or preparing changes for review.
Why use it?
They keep changes consistent with the project's style and help catch errors before tests or builds are considered complete.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

debug-agent AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 46 lines — stays where its author put it; the contents beside it link to each section on GitHub.

General Rules

  • MUST: Use @antfu/ni. Use ni to install, nr SCRIPT_NAME to run. nun to uninstall.
  • MUST: Use TypeScript interfaces over types.
  • MUST: Keep all types in the global scope.
  • MUST: Use arrow functions over function declarations
  • MUST: Default to NO comments. Only add a comment when the user explicitly asks, or when the "why" is truly non-obvious — browser quirks, platform bugs, performance tradeoffs, fragile internal patching, or counter-intuitive design decisions. Never add comments that restate what the code does or what a well-named function/variable already conveys. When in doubt, leave the comment out.
    • Do not delete descriptive comments >3 lines without confirming with the user
  • MUST: Use kebab-case for files
  • MUST: Use descriptive names for variables (avoid shorthands, or 1-2 character names).
    • Example: for .map(), you can use innerX instead of x
    • Example: instead of moved use didPositionChange
  • MUST: Frequently re-evaluate and refactor variable names to be more accurate and descriptive.
  • MUST: Do not type cast ("as") unless absolutely necessary
  • MUST: Remove unused code and don't repeat yourself.
  • MUST: Always search the codebase, think of many solutions, then implement the most elegant solution.
  • MUST: Put all magic numbers in constants.ts using SCREAMING_SNAKE_CASE with unit suffixes (_MS, _PX).
  • MUST: Put small, focused utility functions in utils/ with one utility per file.
  • MUST: Use Boolean over !!.

Testing

Run checks always before committing with:

pnpm check # runs lint + fmt

Development instructions

This is a pnpm monorepo with packages/ (libraries). No external services (databases, Docker, etc.) are required.

Build before test

pnpm build must complete before running the CLI. After modifying source files, always rebuild.

Key commands reference

See root package.json scripts. Quick reference:

  • Install: ni (or pnpm install)
  • Build: nr build (or pnpm build)
  • Lint: pnpm lint — vite-plus lint
  • Format: pnpm fmt — vite-plus fmt
  • Check: pnpm check — lint + fmt combined

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
