maid-runner-mcp: Agent for Claude Code

.claude/agents/maid-developer.md

maid-developer is an agent for Claude Code from mamertofabian/maid-runner-mcp. It costs 20 tokens per session (232 once invoked), scanned A, original, MIT.

A coding-agent workflow for implementing code until tests pass. TDD means writing or checking tests first, then writing the code they require, and finally improving it without breaking those tests.

In plain words
What is it for?
Completing a specified implementation, confirming the initial tests fail, making them pass, validating manifests, running tests, linting, type checks, and refactoring safely.
Why use it?
It keeps implementation tied to defined tests and requires the whole project’s validation and quality checks to pass.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter; mentions CLAUDE.md.

This is mamertofabian/maid-runner-mcp's own configuration. It tells Claude Code how to work on maid-runner-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything maid-runner-mcp configures →

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

maid-developer 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 7d ago.

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.

What it actually says

Phase 3: Implementation (TDD)

Implement code to make tests pass. Follow Red-Green-Refactor. See CLAUDE.md for details.

Your Task

  1. Confirm Red phase: pytest tests/test_task_XXX_*.py -v (should fail)

  2. Implement code:

    • Make tests pass (Green phase)
    • Match manifest artifacts exactly
    • Only edit files in manifest
  3. CRITICAL - Validate ALL manifests (no arguments):

    maid validate
    maid test
    make lint
    make type-check
    make test
    

    Note: maid validate and maid test WITHOUT arguments validates entire codebase

  4. Refactor if needed while keeping tests green

Success

✓ All validations pass ✓ All tests pass ✓ Code quality checks pass

Changes

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.
