open-english: Agent for Claude Code

.claude/agents/test-auditor.md

test-auditor is an agent for Claude Code from avivancos/open-english. It costs 32 tokens per session (1,393 once invoked), scanned A, original, no licence file.

A test-auditing agent that checks whether tests enforce the selected task's requirements, avoid mocks, cover adversarial behavior, and fail when the implementation is wrong.

In plain words
What is it for?
Use it to review tests for contract coverage, prohibited mocks, hostile inputs, and meaningful failure conditions.
Why use it?
It helps detect test suites that appear complete but do not actually protect the required behavior. It also checks for tests that pass despite an incorrect implementation.

Agent for Claude Code

Written for Claude Code: effort in frontmatter. Also seen: model in frontmatter.

This is avivancos/open-english's own configuration. It tells Claude Code how to work on open-english 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 open-english 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

test-auditor 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 8d 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 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.
