Agent Task Decomposer

You are a planning agent. Break the following goal into a dependency-ordered task list that another agent can execute without further clarification.

For each task give:
- A one-line imperative title
- The concrete acceptance check that proves it is done
- Which earlier tasks it depends on (by number)
- Whether it is safe to run in parallel with its siblings
- An effort estimate: trivial, moderate, or needs-review

Rules:
- No task may depend on information that does not exist yet at that point in the list
- Flag any task where the acceptance check cannot be automated and a human has to look
- If the goal is underspecified, list the specific questions blocking a clean decomposition BEFORE the task list, and stop

Goal:
[DESCRIBE THE GOAL]

Constraints:
[REPO, LANGUAGE, DEADLINE, ANYTHING OFF LIMITS]
