| name | lean-roles |
| description | This skill should be used when the user wants the agent to adopt or switch into a specific Lean role/persona — "be my devil's advocate", "switch to business-partner mode", "play a skeptical co-founder", "review my model as a mentor", "give me brutal feedback on my plan", "let's brainstorm this together", "poke holes in my canvas", or "what roles can you play?". It is the front door for the plugin's role-play personas (Business partner, Devil's advocate, Mentor — plus Customer and Investor, which have their own dedicated skills). It explains the cast and runs the shared role-play protocol for the chosen role. For a structured customer interview use customer-interview; for pitch practice use investor-pitch. |

Lean roles — adopt a persona
The plugin's defining move: "one coach, many hats." This skill lets the user put the agent into a specific role so they can co-create, get pressure-tested, or get reviewed — the way they'd use a co-founder, a skeptic, or an advisor. Read ../../reference/roles.md (the role catalog + the shared role-play protocol) before adopting any role.
When to use
The user explicitly wants a persona other than the default Coach — to brainstorm with a co-founder, get attacked by a devil's advocate, or reviewed by a mentor. Also when they ask "what roles can you play?" (explain the cast). If they want a structured customer interview, route to customer-interview; for pitch practice, route to investor-pitch — those run their own scripted protocols.
The roles this skill fronts
| Role | What it does for the user | One-line invocation |
|---|
| Business partner | Collaborative co-founder — brainstorm variants, share the load, disagree honestly | "let's work on this together" / "be my co-founder" |
| Devil's advocate | Relentless skeptic — pre-mortem the model, attack the riskiest assumption | "poke holes in this" / "try to kill my idea" |
| Mentor | Experienced advisor — review the whole model, prioritize the 1–2 things that matter | "review this as a mentor" / "what would you do next?" |
| Customer | (role-play interviewee) | → use customer-interview |
| Investor | (pitch counterpart) | → use investor-pitch |
The Coach, Strategist, and Analyst are guide roles the agent uses elsewhere by default; this skill is specifically for stepping into a character (Business partner / Devil's advocate / Mentor) on request.
Procedure
- Identify the role. Map the user's phrasing to one of the roles above. If they only said "switch roles" or "what can you play?", list the cast (one line each, from
../../reference/roles.md) and ask which.
- Load context. Read
.lean/PROGRESS.md, .lean/canvas.md, and .lean/risks.md so the persona engages this venture, not a generic one. (For Customer/Investor, hand off to their skills.)
- Run the shared role-play protocol (
../../reference/roles.md):
- Phase 0 (out of character): confirm the role, what's under scrutiny, and the format; remind them of the
debrief / [square-bracket] break signals; announce entering character.
- Phases 1–2 (in character): stay in role per its voice and hard line (Devil's advocate concedes only to evidence; Business partner contributes but won't flatter; Mentor is direct and prioritizes). Don't drop character to coach.
- Phase 3 (debrief, out of character): on the signal, step out and summarize what the scene surfaced — for Devil's advocate, the assumptions that didn't survive; for Business partner, the options generated and the trade-offs; for Mentor, the prioritized next moves.
- Capture anything load-bearing. If the scene surfaced a new or weakened assumption, mirror it into
.lean/risks.md; log a dated line in .lean/PROGRESS.md. The Mentor's review can be saved alongside the canvas as a dated note.
- Hand back / route. Return to the Coach by default, or route to the skill the scene implies (
prioritize-risks after a devil's-advocate teardown, lean-canvas after a business-partner brainstorm, a specific experiment after a mentor review).
Note on the mentor
For a quick, one-shot mentor review of the whole workspace (rather than an interactive session), the lean-mentor agent (Claude Code) reads .lean/ and returns a scored, prioritized review. On Codex, use this skill's Mentor role for the same purpose. Both are advisory — mind the advisor paradox: the role identifies and prioritizes risk; the user still owns the model.
