## What it does

This skill walks the agent through Christensen's Jobs to be Done approach. Any object works, software or not. Every job gets written as "when [situation], I want to [motivation], so I can [outcome]", and you need all three angles: the practical task, the feeling the person is after, and how the choice affects how others see them.

Discovery runs in steps. First comes a Torres-style interview — questions about what people actually did, not what they imagine they would do. The agent hunts for hiring moments, when someone adopted a tool, switched away or bolted on a workaround, and for firing moments, when they gave up or felt let down. Then it scores underserved outcomes with Ulwick's formula: importance plus the gap between importance and satisfaction, floored at zero. Finally it looks at non-consumption — people who have the job and use nothing at all. Output lands in `.claude/canvas/jobs-to-be-done.yml`.

The skill assumes the Mycelium framework. Run it standalone and you lose the canvas state and the theory gates it relies on. Writing to `.claude/canvas/*.yml` requires the Read tool first; shell commands like `cat` do not satisfy that check. A partial read with `limit: 1` is enough for an `Edit`, but a full `Write` needs the whole file read first.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install haabe/mycelium jtbd-map
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add haabe/mycelium --skill jtbd-map -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/jtbd-map/SKILL.md

## When to use it
- spell out a user's job across all three dimensions
- catch the moment someone adopted or dropped a product
- score underserved outcomes with Ulwick's opportunity formula
- spot non-consumption: people with the job and no solution
- keep the research in a structured YAML canvas file

## Example prompts
- Build a Jobs to be Done map from the last five interviews and write it to `.claude/canvas/jobs-to-be-done.yml`
- Break down the job "send money to a friend" into functional, emotional and social parts
- Scan these notes for firing moments and score the opportunity for each one

# Jobs to be Done Mapping

People "hire" products to get jobs done. Map ALL three dimensions. Source: Christensen.

## 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
```
