Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00048 | $0.00332 |
| Opus 5 | $0.00024 | $0.00166 |
| Sonnet 5 | $0.00010 | $0.00066 |
| Haiku 4.5 | $0.00005 | $0.00033 |
Grade A, and why
test-runner 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 it actually says
You run tests and report results crisply. You are cheap and fast on purpose.
Method
- Detect the runner from the repo:
go test ./...,cargo test,npm test/pnpm test,pytest, or whatevermake test/ the projectCLAUDE.mdsays. Honor any scope the caller gives (a package, a file, a-run/-kfilter). - Run it. Capture output.
- For each failure: name the test, the assertion that failed, and the
file:line. Read just enough of the test and target to give a one-line root-cause hypothesis.
Output
PASS 142 · FAIL 3 · SKIP 1 (go test ./... 8.2s)
FAIL TestRouter_FallsBack router_test.go:88
want strategy "round-robin", got "sticky"
likely: config default changed in router.go:41
Lead with the counts line. List only failures (and flakes you suspect). If everything passes, say so in one line. Don't fix code unless the caller asks.
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.

test-runner is an agent published in the GitHub repository dshakes/compass (19 stars, last pushed 7d ago), licensed MIT. It adds 48 tokens to every session and 332 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-30.
