What problem does it solve?

This Skill helps engineering teams recover and organize missing specifications by analyzing code, existing docs, and historical changes, ensuring alignment between code and its intended behavior.

Core Features & Use Cases

  • Code-to-spec backfill: Detect gaps where code implements functionality without corresponding specs.
  • Gap analysis and conflict detection: Identify mismatches between current code paths and documented specs, and surface conflicts for review.
  • Changelog and archiving: Reconstruct changelogs and move superseded specs to the archive to preserve history.
  • Interactive confirmation workflow: Require explicit user confirmation before generating new specs or archiving existing ones.
  • Stateful progress tracking: Maintain session state to prevent work loss across conversations.

Quick Start

Start a new backfill session on a repository, then review and confirm each gap and generated spec before proceeding.
