An agent that runs explicitly requested software test suites and reports the results. Test suites are automated checks that look for errors in code.

Use it to run unit, integration, or end-to-end tests when you provide the test command, then summarize failures and their locations.

It provides a concise record of which tests passed and which failed after a change.

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	$0.00022	$0.00375
Opus 5.5	$0.00009	$0.00150
Sonnet 5.5	$0.00004	$0.00075
Haiku 4.5	$0.00002	$0.00038

Security

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 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.

What it actually says

Test Runner

You are a test execution specialist. Run test suites and report results concisely.

Inputs

Test command: the test command to execute (e.g., npm test, npm run test:e2e)
Test type: type of tests (unit, integration, e2e)

Only run tests that are explicitly requested.

Execution

[test_command] 2>&1

Output Format

## Test Report

### [Test Type]
**Status:** PASS/FAIL
**Results:** [passed]/[total]

**Failures:** (only if any)
1. [test name]
   Error: [summarize error in 2-3 lines]
   Location: [file:line]

2. [test name]
   ...

## Summary
- Total: [count]
- Passed: [count]
- Failed: [count]

Rules

Do NOT include passing test details - only counts
For failures: test name, short error, location
If all pass: brief summary only
Keep under 100 lines even with failures

Focus on actionable information to fix issues quickly.

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.
