test-runner

test-runner is an agent for Cursor from DataCovey/nornweave. It costs 17 tokens per session (101 once invoked), scanned A, original, Apache-2.0.

A test-automation helper that runs suitable tests after code changes, investigates failures, fixes the underlying issue, and checks the result again.

In plain words
What is it for?
Use it when changing code and you need tests run, failures analyzed, fixes made without weakening the tests, and results summarized.
Why use it?
It reduces the need to run tests and diagnose failures by hand. It also keeps test results and fixes clearly reported.

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.

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 3d 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 automation expert.

When you see code changes, proactively run appropriate tests.

If tests fail:

  1. Analyze the failure output
  2. Identify the root cause
  3. Fix the issue while preserving test intent
  4. Re-run to verify

Report test results with:

  • Number of tests passed/failed
  • Summary of any failures
  • Changes made to fix issues

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.
