A compact context pack for writing unit tests in one file, with a scorecard showing likely test gaps. Unit tests check small pieces of code in isolation.

Use it when authoring unit tests for a single file and reviewing which cases may still be untested.

It gives a focused view of the code and missing coverage before tests are written.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.

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	$0.00000	$0.01372
Opus 5.5	$0.00000	$0.00549
Sonnet 5.5	$0.00000	$0.00274
Haiku 4.5	$0.00000	$0.00137

Security

Grade A, and why

ca-testit 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 2mo 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.

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.

ca-testit is a command published in the GitHub repository ijanzz5621/mcp-code-guardian (1 stars, last pushed 3mo ago), with no licence file. It costs nothing until one of its globs matches a file; then it loads 1,372 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
