setup SKILL.md skillA
setup from haabe/mycelium is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add haabe/mycelium/setup@git:20261031.d44421bPins git:20261031.d44421b in mdr.lock. Pin the fingerprint instead.

First-run setup for the Mycelium plugin. Creates project-state directories (.claude/canvas, .claude/diamonds, .claude/memory, .claude/harness) and minimal starter files in the user's project. Optionally provisions opencode runtime support (a starter scaffold) when opencode is detected or requested, and declares the gates in .vibe/hooks.toml when Mistral Vibe is. Idempotent — re-running on an initialized project is a no-op. Run this once after installing the Mycelium plugin and before invoking…
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 plugin setup
## First: are Mycelium's hooks running here? (v0.286.0)
Run `find .claude/state/hooks-alive "${TMPDIR:-/tmp}/mycelium-hooks-alive-$(id -u)" -mmin -60 2>/dev/null`. If it prints a path (since v0.318.0 the hooks also stamp the temp folder in a project with no Mycelium state yet, where they do nothing else), say nothing
about it and go on. If it prints nothing, Mycelium's hooks did not run in this session: its gates
and the rules it gives the agent at session start are off, and nothing else will say so. Tell the
user in one line before anything else: "Mycelium's hooks are not running in this session, so its
gates are off. On Codex CLI, open `/hooks`, trust Mycelium's hooks and start a new session; on
Claude Code, check the plugin is enabled in `/plugin`." Then carry on with this skill.
When this skill runs, do the following sequence. The skill is designed to be safe to re-run — every step is idempotent.
## Then: can the gates read the canvas? (v0.290.0)
The safety gates read YAML, so they need a Python with PyYAML. Claude Code installs a plugin's Node
packages but not its Python ones, and documents `${CLAUDE_PLUGIN_DATA}` as the place for a plugin's
…Read the whole file at its exact version.
How to install
mdr add haabe/mycelium/setup@sha256:2f32531ecd7aa604The line at the top of this page pins the label git:20261031.d44421b, 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.
