One command from "plugin installed" to "running brief on your idea." Combines /mycelium:setup (project-state initialization) and /mycelium:interview (10-minute discovery brief) into a single flow. Run this immediately after installing the Mycelium plugin — it's the recommended entry point for first-time users.
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
# /mycelium:start — combined first-time entry When this skill runs, follow the flow below. The skill is designed so a first-time user goes from "plugin installed" to "holding a one-page brief on their idea" in a single invocation. ## Step 1: Welcome (~30 seconds of context, then move on) Output a short welcome before doing anything. Do NOT skip this — the install-to-here gap is the friction point this skill exists to address. The user just installed a 45-skill framework and has no context yet. > "Welcome to Mycelium. > > Mycelium makes the agent think before it builds — it can't skip the hard questions; each step has to clear an evidence check first. Grounded in 30+ established product-thinking frameworks; you'll meet the relevant ones as they come up. > > Two quick steps: > 1. Set up Mycelium's files in `.claude/` — about 10 seconds. Your existing files (CLAUDE.md, README, etc.) aren't changed. A new `.claude/` directory is added, and setup may add an `AGENTS.md` at the project root (it asks first when you are there to answer). …

How to install
mdr add haabe/mycelium/start@sha256:36797ac1024b66e7The line at the top of this page pins the label git:20261018.18c56b2, 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.
