A plugin for testing whether Claude Code skills activate and for benchmarking coding agents. Benchmarking means measuring agents on the same kinds of tasks.

Use it to test skill activation, compare coding-agent performance, run sandboxed evaluations, and add evaluation checks to CI.

It provides a single place to create evaluations, run them locally or in continuous integration, and analyze the results.

Security

Grade A, and why

coder-eval 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 yesterday.

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.
