Get a user's local environment ready before running E2E acceptance tests — verify the dev servers, APIs, and sibling services they need are up and responding, and offer to start whatever is missing (with approval per step). Trigger when the user wants to confirm specific ports or localhost URLs are listening before testing (check if localhost:3000 and the api on 8080 are up, are my services running), spin up their local dev stack, or verify their setup — and whenever another muggle skill…
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
# Muggle Test Prepare > Telemetry first step: see [`_shared/telemetry-emit.md`](../_shared/telemetry-emit.md). Use `skillName: "muggle-test-prepare"`. > 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. Make sure the local services a user needs for E2E acceptance testing are up and ready. Check what's already running, discover sibling service directories by folder name, and offer to start anything that's missing — always with the user in control. Some users start their own services (tmux scripts, docker-compose, a terminal per service). Others want help launching them. This skill handles both: it verifies readiness first, and only offers to start things when something is missing. …

How to install
mdr add multiplex-ai/muggle-ai-works/muggle-test-prepare@sha256:7a08796dfb9f602fThe line at the top of this page pins the label git:20261029.e9a37ed, 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.
