What This Tool Does

Skill Regression Suite Builder is built for deterministic developer and agent workflows.

Build deterministic regression test suites for agent skill updates with risk-weighted pass gates, CI hints, and rollout guidance.

How to Use Skill Regression Suite Builder

  1. 1

    Paste skill release payload

    Provide skill name, version, baseline pass rate, and scenario list in JSON. Each scenario should include user input, expected behavior, and risk level.

  2. 2

    Generate weighted test cases

    Run the builder to create deterministic regression cases with IDs, assertions, and pass thresholds based on scenario risk.

  3. 3

    Review gate target and priorities

    Inspect gate target pass rate, high-risk case count, and priority case IDs to decide whether rollout should stay canary-first.

  4. 4

    Copy suite into CI or eval harness

    Use generated JSON output as your test source for CI checks, trace grading, or nightly skill regression evaluation.

  5. 5

    Re-run after every prompt revision

    Rebuild the suite whenever skill instructions change so test scope stays aligned with current behavior and risk posture.

Frequently Asked Questions

What does Skill Regression Suite Builder output?
It outputs deterministic regression cases with IDs, risk tiers, assertions, pass thresholds, and suite-level gate targets you can use in CI or eval pipelines.
How are pass-rate gates calculated?
Gate targets are risk-weighted. High-risk and medium-risk scenarios raise the target pass rate so production releases require stronger evidence before promotion.
Can I use this with existing eval frameworks?
Yes. The output is JSON-first and designed to be copied into trace grading, prompt eval harnesses, or custom CI checks without extra transformation.
Does this tool execute model calls?
No. It generates test plans only. No model invocation, no external API calls, and no server-side execution occur in this tool.
When should I rebuild a regression suite?
Rebuild whenever skill instructions, tool contracts, or policy constraints change so your test coverage stays aligned with live behavior expectations.
