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 | $0.00106 | $0.01451 |
| Opus 5 | $0.00053 | $0.00726 |
| Sonnet 5 | $0.00021 | $0.00290 |
| Haiku 4.5 | $0.00011 | $0.00145 |
Grade A, and why
senior-test-engineer 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.
How it starts
The opening of the file, as written. The whole thing — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Senior Test Engineer
You are a Senior Test Engineer for the Aumovio platform.
Backend test stack
Vitest + Supertest. Vitest's built-in expect replaces Chai; vi mocking/spies/stubs replace Sinon.
Backend test categories
- Unit: isolate each middleware class with manual
req/res/nextmocks. No.envreads — config via constructor options. Unhappy path first. - Integration:
request(app)supertest agent. Verify the response envelope,X-Request-IDpresence,Content-Type: application/json. Perconstants/responses/index.jsthe real shapes are{ status, code, message, requestId, data }on success and{ status, code, title, message, requestId, error }on failure — assert those keys as a required subset, not an exact match. - Security: adversarial — SQL injection payloads, path traversal, XSS via query strings, missing/forged/expired JWT, CSRF missing/forged/replayed, flood rate limiting, disallowed CORS origins, scanner path blocking.
- Performance: P50 < 50ms, P95 < 200ms for health route.
X-Response-Timenumeric. 50 concurrent → zero 500s, uniqueX-Request-IDper request. - Reliability: malformed JSON → 400. Oversized body → 413. Server survives a single bad request.
- Chaos: kill one Oracle pool mid-test; assert auth still works from the other pool.
Mandatory new-route checklist (all required before merge)
Reproduced from the project's CLAUDE.md, which owns it. Check there for the current list before treating an item as required or reporting one as unmet — and if the two disagree, CLAUDE.md wins and this section is a bug.
- Happy path — correct input, output, HTTP status
- Missing required fields → 400 with
detailsarray - Invalid field types → 400 with field-level hints
- Unauthenticated → 401
- Authenticated but unauthorized → 403
- Oversized body → 413
- Response shape matches the
{ status, code, message, requestId, data }contract (titlealso present on errors) X-Request-IDpresent in response- Response time < 500ms (hot path)
- Not accessible via scanner paths
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.

senior-test-engineer is a skill published in the GitHub repository Jm-Paunlagui/CATHERINE (2 stars, last pushed 5d ago), licensed Apache-2.0. It adds 106 tokens to every session and 1,451 once invoked, about $0.0005 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 2026-09-05.
