Slicing chosen work into tasks and sequencing them: task shape, the dependency graph, the critical path, milestones, and what can run in parallel.
Nine agent skills for the planning loop — frame, discover, options, decompose, estimate, risk, review, replan. Every estimate records what actually happened, so the next range comes from history rather than optimism.

Establishing what is actually true before deciding: current state, verified facts, assumptions worth checking, discovered constraints, and unknowns ranked by decision impact.

Sizing work as ranges, not points: per-task estimates, the critical path total, buffer, schedule, range drivers, and the conditions that would break it.

Turning a vague request into a stated problem: goals, non-goals, measurable success criteria, constraints, and the definition of done. Use when the problem itself is unstated.

Generating candidate approaches and choosing between them: criteria and weights, trade-offs, elimination, and a decision record naming what would change our mind.

Deciding what a plan becomes once reality diverges: classifying the divergence, measuring it, the stop test, and a dated changelog of what changed and why.

Judging whether a plan is ready to act on: readiness checks, a silence audit for what the plan never mentions, blocking findings, and the shortest path to ready.

Finding what could go wrong before it does: a pre-mortem, a register with likelihood and impact, mitigations, rollback, and abort conditions.

Entry point for the planning suite: classifies a planning request, picks the shortest chain of phases, and sequences them. Use when the phase is unclear, or a plan end to end is wanted.
