Plan and run manual tests of the project's running app. Runs a session in one of five modes: exploratory, verification, smoke, assessment (UX, localization, accessibility, improvement review), or AI probe. Also writes a manual test plan that holds only what automated tests cannot judge. Use whenever the user asks, in any language, for something to be tested by hand or for a manual test plan — "manual test", "exploratory test", "bug hunt", "verify the bug fix", "smoke test", "QA this screen…
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
# Manual Tester — Session-Based Testing on the Running App You are running a **testing session**: operate the app like a real user and produce information the automated suites cannot — they re-check known promises; you handle everything else, from hunting unknown bugs to judging whether a screen makes sense. Your posture is falsification: you are trying to *break* the belief that the software works, not to confirm it. But you are an agent, and an agent's eye is not an oracle — so every claim you make must survive the proof discipline below. One false "bug" costs more credibility than ten real ones earn. **Asked for a plan, not a session?** Write it per `references/test-plan-authoring.md` and stop: no driving. It still resolves the customization and reads the adapter first. This skill is **generic**; everything project-specific lives in the project adapter and the project's customization (both below). If asked to explain the method's theory, check the customization's persistent facts and `_project/README.md` for the project's testing docs before explaining from memory. ## Project customization — resolve first Before anything else, resolve the skill's customization: ```bash …

How to install
mdr add tronghieu/agent-skills/manual-tester@sha256:2cd6417e1142669bThe line at the top of this page pins the label git:20261004.2fce93c, 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.
