What problem does it solve? Complex multi-phase work often fails because plans commit to implementation before resolving technical unknowns, leaving reviewers unable to audit progress. This Skill produces restartable execution plans where consequential questions are settled by bounded prototypes first, and every phase checkbox names concrete evidence. ## Core Features & Use Cases - Prototype-first planning: Identify consequential technical questions and resolve them with small, bounded experiments before drafting implementation phases. - Evidence-backed phase checklists: Each phase defines build steps, automated checks, live verification, performance budgets, and human review gates with named evidence artifacts. - Plan maintenance during execution: Update plans through authorized execution, checkpoint progress, and revise phases when assumptions fail. - Use Case: Before migrating a notification system across three PRs, use this Skill to prototype the risky state-management integration, record the verdict, then draft a phased plan with verification commands and review gates for approval. ## Quick Start Use the write-exec-plan skill to prototype the uncertain integration points and draft a phased, evidence-backed execution plan for my migration project.
