# AGENTS.md

A Claude Code plugin in Bun ESM.

## Commands (repository root)

- `just check` runs lint, tests, and validation.

It must pass before done.

- `bun test tests/rules/search-rules.test.mjs` runs one test file.

- `bunx markdownlint-cli2 README.md` lints Markdown.

Headings and code blocks have a 100-column bound.

- `just sandbox` runs Claude Code with this checkout in a separate config.

## Rules

- Keep each `.md` file at 300 lines or less.

Split it into linked parts.

- Write docs in STE-flavored ASD-STE100.

Use no semicolons.

- Use semantic line breaks in all text that is not code: Markdown, comments, messages to Claude, commit messages, and pull requests.

Start each sentence on a new line, and break a long sentence only between clauses.

Never break a line at a column or in a word.

- Write each message that goes to Claude (hook output, deny reasons, skill and agent prompts) in strict ASD-STE100.

Follow Claude's prompting best practices: give the reason, say what to do, use no forceful words, and put code items in backticks.

- Change a usage bound only in `hooks/lib/_budget.mjs`.

Tests pin its copies in code and config, not in prose.

- Keep runtime JavaScript (`hooks/`, `status-line/`, `skills/`, `plugins/`) at 3,000 lines or less.

`tests/budget.test.mjs` pins the bound.

- `hooks/lib` imports only itself.

Event hooks import only `hooks/lib`.

Only the hooks module `hooks/register.mjs` also imports the event actions.

- Tests give commands to the guards as strings.

Never run a guarded command.

- Never patch the Claude Code CLI binary or its npm package, although it is minified JavaScript that you can read.

A patch violates Anthropic's terms of service.

Use only documented extension points.

Reading the bundle for evidence is permitted.

- Add CHANGELOG entries under `[Unreleased]`.

Change versions with `just bump`.
