Goal-driven E2E testing where a browser agent (Playwright MCP / computer-use) reads a natural-language goal and explores the app via the accessibility tree to assert outcomes — no pre-written script. Covers when intent-driven beats scripted, making agent runs deterministic (pinned model, temperature 0, seeded data, bounded steps, explicit success assertion, snapshot-not-pixel), cost/latency control, the accessibility-tree-first interaction model, CI gating, and graduating a stable run into a…
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
<objective> A scripted Playwright test breaks the moment a button moves or a class renames; writing one for a dashboard that changes weekly is a maintenance treadmill. This skill stands up a goal-driven browser agent instead: it reads a natural-language goal, explores the app via the accessibility tree (Playwright MCP `browser_snapshot`), and asserts the outcome against an explicit oracle. The failure mode it prevents is the one that makes teams distrust agents — an agent that reports "success" while stuck on the login page because nothing forced it to prove where it landed. You leave with a deterministic, CI-gated agent run and a graduation path to a durable scripted test once the flow stabilizes. </objective> ## Quick Route | Situation | Go to | |-----------|-------| | Stand up a goal-driven run from scratch | Discovery + `references/setup.md` | | Decide agentic vs scripted for a given flow | Fit: Intent-Driven vs Scripted | | Agent passes one run, fails the next | Determinism | | "How does it click without screenshots?" | Interaction Model | | Runs are slow / burning tokens | Cost and Latency | | Agent reports false success | Success Assertion (the Oracle) | …

How to install
mdr add petrkindlmann/qa-skills/agentic-browser-testing@sha256:279f471e08cae048The line at the top of this page pins the label v1.0, 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.
