Execution Phase

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

Input

The argument to this command is a task ID.

If .agtx/plan.md exists in the current working directory, read it — it already contains the approved plan and all needed context. Do NOT call get_task.

If .agtx/plan.md does not exist, fetch the task description:

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

Instructions

1. Read .agtx/plan.md if it exists (skip get_task), otherwise fetch via get_task
2. Implement the changes
3. Run relevant tests to verify your changes
4. Fix any issues found during testing

Output

When implementation is complete, write a summary to .agtx/execute.md in the current working directory with these sections:

Changes

What files were modified/created and what was changed in each.

Testing

How you verified the changes — tests run, results, manual checks.

CRITICAL: Stop After Writing

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

• Do NOT start new work beyond the plan
• Say: "Implementation complete. Summary written to .agtx/execute.md."
• Wait for further instructions

Output Style

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