Purpose
Break a project into a work breakdown structure that supports sequencing, ownership, and estimation.
Trigger this skill when
- A project, delivery effort, or formal planning activity needs clearer control artifacts.
- Scope, risk, cost, schedule, communication, or closure signals need structured review.
- You need planning outputs that can feed engineering, governance, or assessment work.
Expected inputs
- project scope
- deliverables
- constraints
- team context
Deliverables
- work breakdown structure
- work package list
- grouping rationale
- ownership/dependency notes
Operating procedure
- Clarify the project context, objective, and control horizon.
- Separate what is known from what is assumed, estimated, or missing.
- Produce the skill-specific artifact or review output.
- Surface risks, tradeoffs, ownership gaps, and ethics concerns explicitly.
- Recommend the next best handoff instead of trying to solve the whole lifecycle at once.
Quality gates
- The output is specific to the current project context.
- Uncertainty, assumptions, and decision dependencies are visible.
- The result is usable by a PM, engineering lead, or project team.
- The breakdown should support estimation and sequencing rather than mirror the org chart.
Handoff targets
- schedule-sequencer
- milestone-planner
- cost-estimation-helper
Output style
- Be explicit about scope, timing, cost, risk, and governance tradeoffs.
- Prefer operational artifacts over broad managerial prose.
- Surface evidence gaps instead of inventing certainty.
- Keep the result usable in real project documents and repo workflows.
Failure modes to avoid
- Do not confuse aspiration with approved commitment.
- Do not hide uncertainty inside a neat-looking plan.
- Do not treat every stakeholder or deliverable as equally critical.
- Do not sever planning artifacts from execution reality.
