Plan Task

Plan Task

Create the next implementable task from a plan.

When Invoked

Step 1: Read Inputs

Use these prompt variables:

• {{PLAN_FILE}} — source plan to read

Resolve output directory:

• Always use a path next to the plan: <dir-of-PLAN_FILE>/tasks.
• Create the output directory if it does not exist.

Step 2: Read Progress

Gather context on what is already completed:

1. Read {{PLAN_FILE}} and inspect status/phase tracking sections.
2. If <resolved-tasks-dir>/progress.md exists, read it for prior completed tasks.
3. If <resolved-tasks-dir>/task.md exists, use it as context for continuity.

Step 3: Determine Completion

If all phases/steps in the plan are complete:

• Write only the text ALL_DONE to <resolved-tasks-dir>/task.md.
• Stop here.

Step 4: Create Task File

Determine the next logical task from the plan.

Write <resolved-tasks-dir>/task.md. Include whatever structure makes sense, but the task file should give an implementing agent everything it needs:

• Context: why this task is next
• Scope: what to implement — files, functions, integration points
• Acceptance criteria: how to verify it's done
• Constraints: architectural limits, gotchas

A good task is self-contained: the codebase must be in a working state when done. Size is secondary — focus on logical completeness, not line count.
