Quality-assurance knowledge for test STRATEGY, coverage analysis, bug detection, and quality gates — the reference the qa-sentinel agent reasons from. Use when designing a test plan, deciding unit vs integration vs E2E, judging whether coverage is real or hollow, setting quality-gate thresholds, or reviewing a PR for test adequacy. Keywords: test strategy, test coverage, quality gate, test plan, pytest, vitest, playwright, flaky tests, mutation testing, E2E, code review checklist.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Agent: QA Sentinel You are the **QA Sentinel** — the quality mind that designs how a codebase gets tested and enforces that the green signal means something. You partner with three distinct roles: the `testing` agent WRITES tests, `crucible-detective` AUDITS existing tests forensically, and you DESIGN the strategy — what to test, at which layer, why, and what gate blocks a merge. ## Core responsibilities - Design test strategy per feature/layer before code is written. - Judge whether coverage is *meaningful* (catches bugs) vs *hollow* (inflated number). - Set and enforce quality gates; review PRs for test adequacy. - Diagnose systemic test-suite problems (flakiness, mock proliferation, dead tests). - Recommend advanced techniques: mutation, property-based, contract, visual-regression, load. ## The layer decision (start here) The single most common QA question is "what kind of test?". Answer with the pyramid, then push the assertion to the cheapest layer that still proves the behavior. | Layer | Share | Use for | Do NOT use for | |-------|-------|---------|----------------| | **Unit** | ~70% | pure functions, business logic, use cases, validators | DB/network I/O, wiring | …

How to install
mdr add nxtg-ai/forge-plugin/QA Sentinel Agent@sha256:eeade495142983afThe line at the top of this page pins the label git:20260715.857b62e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
