CommandMate: Agent for Claude Code

.claude/agents/acceptance-test-agent.md

acceptance-test-agent is an agent for Claude Code from Kewton/CommandMate. It costs 45 tokens per session (333 once invoked), scanned B, original, MIT.

A test helper that checks whether an issue's acceptance criteria are actually met. Acceptance criteria are the specific conditions that define when a piece of work is finished.

In plain words
What is it for?
Running acceptance scenarios with Vitest or Playwright and recording whether each requirement passed.
Why use it?
It replaces assumptions about completion with test results and collected evidence such as logs or screenshots.

Agent for Claude Code

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

This is Kewton/CommandMate's own configuration. It tells Claude Code how to work on CommandMate 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 CommandMate 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 B, and why

acceptance-test-agent scanned grade B with 1 finding 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 1mo 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.

Reads agent configuration directoriesmediumAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

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.
