## What it does

The skill runs an onboarding questionnaire when initializing a repository or exploring a codebase that lacks docs. It inspects Mycelium hooks and checks `.claude/state/interview-in-progress.md` before doing anything else. If an earlier session stopped midway, the agent resumes with the next unanswered question instead of restarting from scratch. On a clean canvas, it calibrates project scope and poses four questions to generate a one-page summary.

It enforces strict conventions for modifying `.claude/canvas/*.yml` files. The agent must use the `Read` tool before altering data, relying on a single-line peek to conserve tokens for partial updates and scanning numeric ID ranges with grep to stop key collisions.

Operating without the Mycelium harness disables built-in theory gates and canvas state tracking.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill interview -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/interview/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/interview/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill interview -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/interview/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill interview -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/interview/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install haabe/mycelium interview
```

2. **Manually: put the files in place**
- File: `.github/skills/interview/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill interview -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/haabe/mycelium --path plugins/mycelium/skills/interview
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/interview/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill interview -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/haabe/mycelium/tree/HEAD/plugins/mycelium/skills/interview/SKILL.md

## When to use it
- assemble a concise project brief in ten minutes
- resume an unfinished onboarding interview from saved state
- capture product vision and goals inside purpose.yml
- prevent duplicate ID assignments across canvas files

## Example prompts
- Run the onboarding interview for this new repository
- Resume our unfinished project interview
- Interview me about the vision and north star for this app

# Interview Skill

## 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.

Progressive onboarding through structured discovery conversation.

## Preflight: Read target canvas file(s) before any Write/Edit

**Hard rule.** Before issuing `Write` or `Edit` against any `.claude/canvas/*.yml`, use the **Read tool** on that file in this session. Claude Code's Read-before-Write check requires the `Read` tool specifically — `cat`/`head`/`grep` via Bash do NOT satisfy it.

**Edit vs Write — different cost profiles** (verified 2026-05-14):
- **`Edit`** (exact-string replacement): `Read` with `limit: 1` satisfies the check at ~50 tokens. State-tracking is per-file, not per-byte — subsequent `Edit` calls work anywhere in the file. Use this for partial updates against large canvas files (e.g., `purpose.yml` at 800+ lines).
- **`Write`** (full replacement): do a **full Read** first. Write obliterates the file; you should see what you're about to replace. The `limit:1` shortcut is *not* appropriate here.

**ID-bearing entries — scan the ID space before assigning** (added 2026-05-15, v0.23.19): When adding a new component, opportunity, solution, or any other ID-bearing entry to a canvas file, run a Bash grep first to confirm the next ID in your prefix sequence is actually free:

```
grep -o "<prefix>-[0-9][0-9]*" .claude/canvas/<file>.yml | sort -u -t- -k2 -n | tail -3
```
