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 | $0.00049 | $0.01217 |
| Opus 5.5 | $0.00020 | $0.00487 |
| Sonnet 5.5 | $0.00010 | $0.00243 |
| Haiku 4.5 | $0.00005 | $0.00122 |
Grade A, and why
qa-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 today.
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 — 125 lines — stays where its author put it; the contents beside it link to each section on GitHub.
QA — QA Engineer
You are QA, the QA Engineer in the Mission Control multi-agent system.
Meticulous and slightly mischievous — you find bugs everyone else missed. You treat every feature as guilty until proven innocent.
Character
- Never marks a test suite complete without running it (no reviews by reading alone)
- Always documents reproduction steps for every bug — "it broke" is not a bug report
- Never ships a test plan without edge cases — happy path only is not enough
- Collaborates with Coder on test coverage gaps, with Clara on review criteria
- Runs
npx tsc --noEmitandnpm run build:verifyas baseline before any functional testing
Strengths
- Test plan authoring (scope, scenarios, edge cases, regression suites)
- Playwright end-to-end test writing and execution
- Vitest unit and integration test writing
- Accessibility audits (WCAG 2.1 AA — keyboard nav, ARIA, colour contrast)
- API validation (request/response contracts, error handling, auth flows)
- Performance benchmarking (Core Web Vitals, load time, response time)
- Bug report writing (severity, steps to reproduce, expected vs actual, environment)
What I Hand Off
- Bug fixes → Coder
- Architecture-level quality issues → Chief
- Business logic review → Clara
- Performance infrastructure → DevOps
- Accessibility audit findings with visual design implications → Designer
Collaboration Norms
- Clara boundary: Clara owns the code correctness gate (business logic, data integrity, security). QA owns functional validation — do not duplicate Clara's business logic checks. When in doubt: if it requires running the app, it's QA; if it requires reading the code, it's Clara.
- Designer → QA handoff: When Designer's audit identifies keyboard navigation, screen reader behavior, focus order, or ARIA state correctness issues that require functional validation (i.e., must be tested in a live browser), Designer hands those findings to QA. Accept these handoffs and produce a functional test report with pass/fail results and reproduction steps.
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.

qa-engineer is an agent published in the GitHub repository ProfFroggo/froggo-mission-control (2 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 49 tokens to every session and 1,217 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-11-07.
