What is coverage-reporter?

A test-coverage reporter that runs the extension's unit and integration tests and compares coverage changes with the required 80% policy.

Use it after a test-writing batch to check statement, branch, function, and line coverage against the policy in CLAUDE.md.

It shows whether a batch changed the coverage result, so you do not have to calculate pass or fail by hand.

Per session 65 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 757 The whole file, excluding the scripts and references it only reads on demand.

Origin unknown No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00065	$0.00757
Opus 5.5	$0.00026	$0.00303
Sonnet 5.5	$0.00013	$0.00151
Haiku 4.5	$0.00006	$0.00076

Security

Grade A, and why

coverage-reporter 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.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
