What problem does it solve? Long-running agent workflows lose context between sessions when progress notes are scattered or overwritten. This Skill standardizes how progress files are updated so blockers, decisions, and verification status survive across sessions. ## Core Features & Use Cases - File Priority Resolution: Locates the active progress file by checking .specs/project/STATE.md, then docs/harness/progress.md, then agent-progress.md. - Structured Sections: Enforces required sections including Current Active Work, Verification Status, Blockers, Decisions Log, and Next Best Action. - Preservation Rules: Appends dated decisions, keeps existing blockers, and records verification as actual command output or an explicit not-run reason. - Use Case: After finishing a coding task in a multi-session harness workflow, update the project progress file so a fresh session can resume without re-reading the entire history. ## Quick Start Update the project progress file with the current work status, verification results, and next action while preserving existing blockers and decisions.
