qa-edge-hunter skillF

qa-edge-hunter is agent-read markdown (skill) from nguyenvanphituoc/shapeup-sdlc-plugin: Use this skill for the post-PASS exploratory QA pass — Shape Up's "QA is for the edges", made explicit for the harness. Triggers on: "hunt edge cases", "QA pass on this feature", "exploratory test the running app", "edge hunt before ship", "run qa-edge-hunter", "the evaluator passed — what did it miss?". tech-lead invokes it after the run's first PASS at GATE L3, before SHIP; it also runs standalone given a spec folder, a PASS EVAL report, and a running app, or on a tech-lead --order dispatch. I.

Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent.

What the file says

# QA Edge Hunter — the post-PASS edge pass (v1.1)

Shape Up, Ch. 13: QA comes in **toward the end**, hunts **edge cases outside the core**,
and its issues are **nice-to-haves by default** that the team triages. This skill is that
role for the harness. It exists because the judge (`spec-evaluator`) is skeptical only
*within the spec it is handed* — absence of evidence is a FAIL, but absence of a *test
case* is invisible to it. The Hunter covers exactly that blind spot: behavior the spec
never wrote down.

```
tech-lead: ... GATE L2 → EVAL → GATE L3 PASS ──► QA EDGE HUNT (you) ──► SHIP S.0 triage → L4
                                                  charters · hunts · ~ findings → ledger
            GATE L3 FAIL → fix round (never reaches you — conformance first, edges after)
```

**Division of labor (a settled design decision, not a convention):**

| Tier | Owner | When |
|---|---|---|
| Derivable tests (boundaries, error codes, no-go breaches the spec implies) | `ba` `## Test Surface` + evaluator `test-surface-conformance` | spec time / every EVAL |
| **Exploratory edges (this skill)** | `/qa-edge-hunter` | once, post-first-PASS |
