adopt SKILL.md skillA
adopt 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/adopt@git:20261011.6a101dfPins git:20261011.6a101df in mdr.lock. Pin the fingerprint instead.

Bring Mycelium into a project that already has code. Detects that the repo predates the framework, asks before touching anything, then reads the codebase to draft what it CAN establish (delivery, solution shape) and — the actual point — names what it cannot (purpose, strategy, real user evidence). The output is a discovery backlog with a head start, never a filled canvas.
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
# Adopt (brownfield entry)
## 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.
`/mycelium:start` assumes a blank page. Most projects are not a blank page. This
skill is the entry point when the code came first.
## When to Use
- A repo with existing source and no populated canvas (the SessionStart
brownfield check points here).
- A maintainer who wants discovery on a product that already ships.
- NOT for a new idea — that is `/mycelium:start`.

How to install
mdr add haabe/mycelium/adopt@sha256:0b622b537ef0c73cThe line at the top of this page pins the label git:20261011.6a101df, 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.
