What problem does it solve? Complex development work often loses track of scope, decisions, and verification evidence across long sessions, context compaction, or handoffs. This Skill provides a disciplined workflow that carries substantive work from goal clarification through planning, execution, and verification while preserving resumable state. ## Core Features & Use Cases - Workstream State Management: Maintains a private gitignored checkpoint under .eyr-plans/ capturing outcome, plan, decisions, evidence, and next actions so work survives pauses, compaction, and resumption. - Atomic Change Planning: Records independently valid atomic changes with repository/file scope, ownership, dependencies, and verification before substantial implementation or delegation. - Verification Contract: Defines acceptance checks during planning, runs repository gates like make lint, make check, and make verify, and requires evidence-based reuse rules before declaring completion. - Use Case: You ask the agent to implement a multi-file feature across two repositories. The skill plans atomic commits, saves checkpoints before long operations, runs the prescribed gates, and finishes with a clear next-step choice to hand verified changes to the commit workflow. ## Quick Start Ask the agent to develop and verify a specific feature or fix, and it will plan atomic changes, execute them, run the repository checks, and preserve resumable state.
