# mocked-persona-interview

For solo and hobby projects where real user interviews are off the table: the skill runs interviews with invented personas and keeps them from becoming a rubber stamp for your own assumptions.

## What it does

The skill belongs to the Mycelium framework and expects its plugin to be installed first, because it relies on canvas state and theory gates. Without that setup a standalone run skips the scaffolding the workflow is built on.

The method is strict about order. You brainstorm six archetypes in chat with the agent before any profile gets written: a founder twin, the most likely real user, a sceptic with a solid reason to refuse, someone squeezed for time or money, a niche case, and a wildcard from outside the assumed audience. The list is committed to the decision log first. Then each persona gets a short profile, and the interview comes after it, following questions from the framework's real-interview skill.

One more rule concerns writing files: `Write` and `Edit` against `.claude/canvas/*.yml` need a prior Read call through the Read tool, since a Bash `cat` does not satisfy the check. When actual users can be reached, this is no replacement for `/mycelium:user-interview`.

Install with `npx skills add haabe/mycelium --skill mocked-persona-interview -a claude-code`; the skill lands at `~/.claude/skills/mocked-persona-interview/SKILL.md`.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill mocked-persona-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/mocked-persona-interview/SKILL.md

## When to use it
- test product assumptions with no research budget
- build six distinct archetypes instead of agreeable stand-ins
- commit stop conditions before the interview starts
- mark guesses apart from confirmed findings

## Example prompts
- Draft the persona spectrum for my project and log it before writing any profiles.
- Interview the adversarial persona who already has a workflow they like.
- Read `.claude/canvas/opportunities.yml` with the Read tool before adding a new entry.

# Mocked Persona Interview Skill

A disciplined alternative to real user interviews when:
- You're a solo developer and cannot talk to users this week
- You're on a hobby/learning project with no user research budget
- You're running a meta-project dogfood session (see `dogfood_modifier`)
- You're in early L0/L1 exploration where real interviews are premature

**This skill is NOT a substitute for `/mycelium:user-interview` when real users are available.** Mocked personas are simulation. They catch some mistakes, miss others, and — without discipline — become a confirmation-bias machine. This skill's job is to enforce the discipline.

## 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.
```
