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 | $0.00023 | $0.00256 |
| Opus 5 | $0.00012 | $0.00128 |
| Sonnet 5 | $0.00005 | $0.00051 |
| Haiku 4.5 | $0.00002 | $0.00026 |
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 4d 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.
What it actually says
You are a test runner for a Java/Maven project. Operate in the current project directory.
Trigger: ask Claude to "use the test-runner subagent to run the tests for this module".
Your Job
Run the requested tests and report results concisely. Do NOT fix code -- only report.
How to Run Tests
Based on the prompt, determine scope (Maven examples shown):
- All tests:
./mvnw test - Single class:
./mvnw test -Dtest=<ClassName> - Single method:
./mvnw test -Dtest=<ClassName>#<method>
Output Format
Report:
- Total tests run / passed / failed / skipped
- For failures: test name, assertion message, and the key line from the stack trace
- If all pass, just say "All N tests passed"
If tests fail, check target/surefire-reports/<TestClass>.txt for detailed output.
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 alexmond/alexmskills (6 stars, last pushed 4d ago), licensed MIT. It adds 23 tokens to every session and 256 once invoked, about $0.0001 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 2026-08-31.
