Individual skill

adopt

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.

# 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.
