maid-runner-mcp: Command for Claude Code

.claude/commands/improve-tests.md

improve-tests is a command for Claude Code from mamertofabian/maid-runner-mcp. It costs 6 tokens per session (112 once invoked), scanned A, original, MIT.

A command for improving tests in a specified part of a codebase. It checks that tests make meaningful assertions instead of merely running code, including checking outputs and side effects.

In plain words
What is it for?
Reviewing existing tests, adding missing cases, checking printed output and state changes, and running the project's validation and test commands.
Why use it?
It helps find weak tests and adds edge cases and error scenarios, reducing the chance that broken behavior goes unnoticed.

Command for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: positional $N argument.

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

improve-tests 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 9d 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

Improve tests in: $1

Tasks:

  1. Review existing tests - flag any without assertions (smoke tests)
  2. Add edge cases and error scenarios
  3. Ensure tests USE artifacts AND ASSERT on outputs/side effects
  4. Use capsys for stdout, verify return values, check state changes
  5. Validate: maid validate and maid test

No smoke tests. See docs/unit-testing-rules.md.

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.
