Deeply studies how the user's own test automation is built — inside the product repo or in a separate test repo — in focused sessions that each write their own file in `.qa-skills/`, the repo's long-term memory for other QA skills. It covers stack and how to run every suite (e2e UI, API, contract, unit, performance, mobile); the architecture (Page Objects, Screenplay, services, step layers, how far the code really follows OOP or is inconsistent); how test cases are written…
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
# Test Stack Discovery Study the user's tests the way a senior automation engineer studies a codebase in their first week on a team — patiently, file by file, until they could write a new test that nobody would notice wasn't written by the team. Then write that knowledge down in `.qa-skills/`, where other skills (automation, test design, review, exploratory) read it before they work. **This skill is meant to be slow and thorough.** Its output is reused by every later skill, many times, so a gap or a wrong guess here is multiplied downstream. Take the time to read the architecture for real, follow how a test flows through its layers, and confirm every convention with counts. Speed is not a goal; fidelity is. It **reads and documents** — it never runs tests, installs dependencies or edits the user's code; it writes only inside `.qa-skills/`. …

How to install
mdr add marina-gajego/qa-skills/test-stack-discovery@sha256:9b9d31e21689b267The line at the top of this page pins the label git:20261026.99990be, 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.
