Plan Task

The user wants to start a planning session.

Step 1: Ask How to Proceed

FIRST, use the AskUserQuestion tool to ask how they want to provide the task:

Question: "How would you like to describe what you want to plan?"
Options:
1. "Interview me" - I'll ask detailed questions to understand your requirements
2. "I have a spec file" - Provide a path to an existing file (e.g., SPEC.md)
3. "I'll paste a description" - You'll paste in the task description

Step 2: Handle Based on Response

Option 1: Interview Mode

Interview the user in depth using the AskUserQuestion tool to understand what they want to plan.

Interview guidelines:

• Start by asking what feature/system they want to build
• Go deep on technical implementation details: architecture, data models, APIs, state management
• Explore UI & UX concerns: user flows, edge cases, error states, accessibility
• Probe for tradeoffs: performance vs simplicity, build vs buy, scope decisions
• Ask about constraints: timeline, team size, existing systems to integrate with
• Uncover concerns: security, scalability, maintenance, testing strategy
• Ask non-obvious questions - don't ask things with obvious answers
• Continue asking questions until you have a comprehensive understanding
• Each round, ask 2-4 focused questions on different aspects

When the interview is complete, write a comprehensive spec to .pl4n/task-temp.md summarizing everything discussed, then proceed to Step 3.

Option 2: Spec File

Ask for the file path, then proceed to Step 3 using that file directly with --file.

Option 3: Paste Description

Ask the user to paste their description. Once received, write it to .pl4n/task-temp.md, then proceed to Step 3.

Step 3: Initialize and Run

Prerequisites: If pl4n is not found (exit code 127), run bun install first.

1. Run pl4n init:

   • For spec file: pl4n init --file "<filepath>"
   • For interview/paste: pl4n init --file .pl4n/task-temp.md

2. Capture the session_id from the JSON output

3. Run pl4n wait --session <session_id> to wait for agents to complete

4. When complete, tell the user:

   • The path to the plan file (.pl4n/sessions/<id>/turns/001.md)
   • They should review and edit the file
   • When done editing, use /pl4n:continue <session_id> to start the next turn
   • Or /pl4n:approve <session_id> if satisfied
