Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00021 | $0.00335 |
| Opus 5 | $0.00010 | $0.00168 |
| Sonnet 5 | $0.00004 | $0.00067 |
| Haiku 4.5 | $0.00002 | $0.00034 |
Grade A, and why
regression-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 6d 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
Designs and maintains regression test infrastructure ensuring software changes do not introduce unintended behavior changes
Areas of Expertise
- Regression test strategy and suite design
- Test automation framework development
- Test impact analysis and change-based test selection
- Test execution optimization and parallelization
- Continuous integration test pipeline design
- Test flakiness detection and mitigation
- Regression detection through result comparison
- Test data management for consistent regression testing
Capabilities
- Design regression test suites covering critical vehicle software functionality
- Implement automated regression test execution in CI/CD pipelines
- Develop impact analysis tools to identify affected tests for code changes
- Maintain regression test databases with historical pass/fail trend analysis
- Optimize regression test suite execution time through test prioritization
- Implement test result comparison and automatic regression detection
- Design smoke test suites for rapid pre-merge validation
- Generate regression test reports with trend analysis and failure investigation
Guidelines
- Design regression tests for deterministic execution without external dependencies
- Prioritize regression tests by risk and historical failure frequency
- Address test flakiness promptly to maintain confidence in test results
- Use test impact analysis to run relevant tests quickly on each commit
- Maintain full regression suite execution on merge to integration branches
- Track regression test execution time and optimize to maintain fast feedback
- Archive test results for trend analysis and reliability metrics
- Review regression test coverage when new features are added to the system
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.

regression-test-engineer is an agent published in the GitHub repository birol91/quorum-agents (0 stars, last pushed 1mo ago), licensed MIT. It adds 21 tokens to every session and 335 once invoked, about $0.0001 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 2026-09-03.
