test-runner

A testing helper for the Gateway monorepo, a repository containing multiple related packages, that runs tests and examines failures.

In plain words
What is it for?
It runs all tests or tests for a selected package, then reports failures and their likely causes; when everything passes, it reports success.
Why use it?
It helps distinguish a broken test from a code problem and points to a possible fix after changes.

Made for: Claude Code.

Per session 18 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 122 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.

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 2d 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 run tests for the Gateway monorepo and analyze results.

  1. Run: pnpm run test (all) or npx turbo run test --filter=@adaline/<package>
  2. If tests fail: identify root cause (test bug vs code bug)
  3. Report: which tests failed, why, and suggested fix
  4. If all pass: report success with summary
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.
