Planning Phase

You are in the planning phase of an agtx-managed task.

Input

The argument to this command is a task ID. Fetch the task description using the agtx MCP tool:

mcp__agtx__get_task(task_id: "<the id passed to this command>")

Use the description field as the task to work on. Also check for .agtx/research.md if a research phase was completed first.

Instructions

1. Fetch the task description via get_task
2. If .agtx/research.md exists, read it for prior analysis
3. Explore the codebase to understand relevant files, patterns, and architecture
4. Identify all files that need to be created or modified
5. Create a detailed implementation plan

Output

Write your plan to .agtx/plan.md in the current working directory (do NOT navigate up — write directly to .agtx/plan.md relative to where you are now) with these sections:

Analysis

What you found in the codebase — relevant files, patterns, dependencies.

Plan

Step-by-step implementation plan — files to modify, approach, order of changes.

Risks

What could go wrong — edge cases, breaking changes, areas needing extra care.

CRITICAL: Stop After Writing

After writing .agtx/plan.md (in the current working directory):

• Do NOT start implementing
• Do NOT modify any source files
• Say: "Plan written to .agtx/plan.md. Waiting for approval."
• Wait for explicit instructions to proceed

Output Style

Terse. No pleasantries. Fragments OK. Short synonyms. Code exact. Status updates: one line. Pattern: [what] [why]. Done.
