What problem does it solve? Multi-step initiatives lose context when a conversation ends or an agent session resets. This Skill turns an initiative into a directory of Markdown plan files — goals, ordered steps, work units, verification instructions, progress trackers, and handoff notes — that another agent can resume and execute without reconstructing missing context. ## Core Features & Use Cases - Plan decomposition: Creates a plan directory with a plan description, work-unit inventory, goals, and step files, each written through validated helper scripts. - Adversarial review gates: Requires an independent reviewer pass with findings, fix-key verification, and an approval gate before a plan counts as ready. - Progress tracking and resumption: Generates plan-level and goal-level progress trackers plus bounded context snapshots so work can resume across sessions. - Use Case: Ask the agent to plan a multi-week refactor; it produces a validated plan directory with ordered goals and steps, passes adversarial review, and later sessions resume execution from the trackers. ## Quick Start Use the planning skill to create a durable, resumable plan for migrating our billing service to the new API, with goals, ordered steps, and progress trackers.
