## Description

Use when the user wants product requirements rather than code: 'write a PRD', 'product requirements', 'spec this feature for the team', 'ooo pm'. Runs a PM-focused interview with automatic question classification and produces a PRD/PM document. Not for implementation requests.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# /ouroboros:pm

PM-focused Socratic interview that produces a Product Requirements Document (PRD).

## Required Skill Capabilities

- `ask_user`: ask the user through the active runtime's `ask_user` capability.
- `call_mcp`: `ouroboros_pm_interview` holds the interview state and writes the PRD.
- `orchestrate_subagents`: run the evidence lanes each question carries.
- `refine_answer`: confirm the structured answer before it is sent (Refine gate).
- `run_shell`: copy the finished PRD to the clipboard, when available.

## Instructions

Updates are checked in the background; if your context carries an Ouroboros update notice, mention `ooo update` once after the first question.

### Step 1: Loading MCP tools (deferred-schema guard)

Ouroboros tools may be deferred, and a schema loaded on one turn can unload by the next. Immediately before each `ouroboros_*` call, load it with the active runtime's tool-discovery capability: `"+ouroboros pm_interview"` for `ouroboros_pm_interview`. A call whose schema is not loaded fails with "Invalid tool parameters". If the tool is already callable, discovery is a no-op and an empty result is expected. Use the fallback only when the tool is genuinely absent.

Fallback: fail closed. Do not inspect or edit `~/.claude/mcp.json` and do not add a direct Python fallback. Tell the user this, then stop:

```
The PM interview MCP tool is unavailable in this runtime.

Configure a supported CLI-backed host with:
  ouroboros setup --runtime <codex|opencode|kiro|copilot|hermes>

Then restart that host and retry ooo pm. Claude SDK profiles ([claude] and
[claude-sdk]) stay on MCP 1.x; the separate [mcp] server uses [claude-cli]. Do
not combine both MCP majors or add a direct Python fallback.
```

### Step 2: Start Interview

```
Tool: ouroboros_pm_interview
Arguments:
  initial_context: <user's topic or idea>
  cwd: <current working directory>
```

The response carries the first question, so Step 3 applies to it, evidence lanes included.
