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 | $0.00000 | $0.00364 |
| Opus 5 | $0.00000 | $0.00182 |
| Sonnet 5 | $0.00000 | $0.00073 |
| Haiku 4.5 | $0.00000 | $0.00036 |
Grade A, and why
qb 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 9d 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
Behavior validation - verify tests pass and outputs match design.
Purpose
Verify that implemented code behaves correctly:
- Build succeeds
- Tests pass
- Behavior matches design specifications
- Edge cases from critique are handled
Execution
Use the quality-behavior agent.
Input:
build-report.md— What was builtdesign.md— Expected behaviorcritique.md— Edge cases to verify
Process:
- Run build:
npm run build - Run tests:
npm test(if tests exist) - Verify specifications:
- Check behavior against design.md requirements
- Verify edge cases from critique.md are handled
- Append results to
qa-report.md
Verification Matrix
| Requirement | How to Verify |
|---|---|
| API returns X | Check response shape |
| Handles empty data | Check code path |
| Auth required | Check middleware |
| Multi-tenant | Check user_id filter |
Output
After validation, report:
## Quality Behavior Complete
**Verdict:** [PASS | FAIL]
### Build
- Status: [PASS | FAIL]
- Warnings: [N]
### Tests
- Status: [PASS | FAIL | NO_TESTS]
- Passed: [N]
- Failed: [N]
### Specification Compliance

### Edge Cases

### Issues Found

### Next Step
Run `/qd` for documentation check.

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.

qb is a command published in the GitHub repository TheAstrelo/Claude-Pipeline (44 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 364 tokens. 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 2026-08-30.

tdd
A command for test-driven development, a method where you write a failing test first, then code to pass it, and finally improve the code.
web-checklist
A checklist command for testing a website after a Git merge. It records checklist items in a file so progress can be viewed and individual checks can be marked complete.
test-coverage
Analyze test coverage and generate missing tests to reach 80%+ coverage.
test-suite
Run comprehensive test suite with coverage analysis.
