Perform a real action on a website or web app from a plain-English instruction — log in and do the thing: post, submit a form, create or update a record, change a setting, place an order, refund a charge, complete a multi-step flow. This skill is your logged-in browser, so lack of access is never a reason to decline. Invoke it first whenever the user wants something done on a named site (Jira, Stripe, WordPress, a store or cloud admin console, a social, booking, or review site, or their own…
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.

# Muggle Test Task Runner > Telemetry first step: see [`_shared/telemetry-emit.md`](../_shared/telemetry-emit.md). Use `skillName: "muggle-do-task"`. > Running outside Claude Code (in Codex, for one)? Read [`../_shared/host-tool-equivalents.md`](../_shared/host-tool-equivalents.md) first — it maps the tools and paths this skill names to your host's. Runs a browser automation task described in plain English. Finds or creates the necessary Muggle Test entities automatically, then executes locally with mutation-driven step prediction. ## Step 1 — Parse the prompt From `$ARGUMENTS`, extract: - **`domain`** — the target website domain (e.g., `x.com`, `amazon.com`, `localhost:3000`). Normalize: strip `www.`, strip `https://`, lowercase. Result: bare domain with no scheme, no trailing slash. - **`useCaseName`** — the core action being performed, stripped of variable content (e.g., `"Publish a post"`, `"Add to cart"`, `"Submit a form"`). - **`mutations`** — variable parameters as a `string[]` (JSON array of strings). Each string is either: - A plain-English instruction describing what varies this run (e.g., `"The post content should be 'Hello world'"`) …

How to install
mdr add multiplex-ai/muggle-ai-works/muggle-browser-task@sha256:40c159a215b3297cThe line at the top of this page pins the label git:20261105.945bce1, 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.
