task-decomposer

# task-decomposer — turn vague goals into actionable plans ## When to use Trigger phrases: - "How do I…" - "Help me plan…" - "I want to build/launch/migrate/refactor…" - "Where do I even start?" Do NOT use when: - The task is already concrete and atomic ("fix this typo") - The user explicitly says "just do it" — they don't want a plan, they want execution - The decomposition is trivial (≤2 steps) ## Process ### 1. Clarify the goal Restate it in one sentence. If anything is ambiguous, ask one targeted question before decomposing. Avoid 5-question intake forms. ### 2. Identify the **DoD** (Definition of Done) What does success look like, concretely? Examples: - "✅ when the test suite passes on CI" - "✅ when 10 real users have used it without crashes" - "✅ when the doc is approved by manager" Without a DoD, the plan is open-ended. ### 3. Decompose Break into tasks that are: - **Atomic enough** that an estimate is meaningful (~15 min to ~4 hr each) - **Verifiable** — each step has a clear "done" signal - **Ordered** — note explicit dependencies (`#3 blocked by #1`) - **Sized** — give a rough estimate: XS (<30m) / S (1-2h) / M (half-day) / L (full day) / XL (>1 day, recommend splitting further) ### 4. Flag unknowns Mark anything you couldn't decompose because of missing info. These are research tasks: "Investigate X (S) — required before deciding between approach A or B". ### 5. Suggest a critical path Identify the 2-3 steps that gate everything else. The user...
