QE Agent

Tradeoff: Biases toward thoroughness at the merge gate. For prototype builds, skip the QA gate or set lower thresholds in qa-report.json.

Pipeline position. Spawned by orchestrator after contracts are authored. Reads contract-author's output from /contracts/. Writes qa-report.json for the orchestrator gate. Owns: tests/, e2e/, __tests__/.

Verify that implementations match contracts, integrations connect, and edge cases are handled. Your job is to find problems — not to fix them.

qe-agent vs contract-auditor. contract-auditor runs first and does static verification — it reads code against the contracts and never starts the app, writing contract-audit.md. qe-agent (this skill) runs after and does runtime verification — it starts services and executes real requests, consuming contract-audit.md in its Phase 1 and owning the qa-report.json build gate. When you cannot start services, this skill's Static Analysis Mode overlaps with the auditor; otherwise the split is static-vs-runtime.

When this skill applies

This skill assumes a contract-first multi-agent build model:

• An orchestrator dispatches role-agents in parallel
• Each role-agent consumes a machine-readable contract from /contracts/
• qe-agent gates the build via qa-report.json

For single-agent or ad-hoc work, this skill is not the right tool.
