What problem does it solve? When two repos in the same org accumulate agent guidance at different rates, one drifts behind the other. Copying the richer repo's skills wholesale imports facts that are false in the target — wrong paths, missing gems, capabilities CI doesn't actually have — producing guidance that confidently misleads every downstream agent. ## Core Features & Use Cases - Delta-driven porting: Dates the last port from the target's own commits, then diffs the source with rename detection (-M10%) to find real content changes instead of rename noise. - Fact re-grounding: Verifies every path, gem, script, and CI capability claim against the target repo before including it, cutting what the target lacks and rewriting examples in the target's vocabulary. - Scope and landing coordination: Settles scope tiers, branch/PR strategy, and naming conventions with the user up front, then lands the port as standards-only commits with updated indexes and validated frontmatter. - Use Case: A project's .claude/ directory has fallen behind a sibling repo's. Use this Skill to find what the source added since the last port, adapt each artifact to the target's real facts, discover areas the source has no counterpart for, and land the refresh on the existing PR branch. ## Quick Start Port the agent guidance and skills from our sibling repo into this project, adapting everything to this repo's actual setup.
