Test Coverage Check

Test Coverage Check is a command for coding agents from leihuang830102-hash/Opencode-Howto. It costs 11 tokens per session (71 once invoked), scanned A, a copy of Test Coverage Check, MIT.

A command that checks test coverage, meaning which parts of the code are exercised by tests, and reviews the quality of those tests.

In plain words
What is it for?
Use it to inspect coverage, find missing tests, assess test quality, suggest edge cases, and check whether important code paths are tested.
Why use it?
It helps reveal untested code paths and missing boundary cases that ordinary coverage percentages may not explain.

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 Coverage Check 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 3d 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.

Origin

This is a copy

100% identical to Test Coverage Check — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
