What problem does it solve? When agreements and decisions are recorded across sessions, there is often no clear way to verify later whether they are still correct. This Skill establishes an anchor for each agreement—a concrete pointer to where correctness can be checked—so future sessions can validate decisions against code, specs, or source materials. ## Core Features & Use Cases - Anchor Creation: Interactively define new verification anchors for decisions, logs, or materials that lack one. - Anchor Updates: Refresh existing anchors when code paths change, URLs move, or related decisions are replaced. - Four Anchor Types: Supports implemented code references, external spec URLs, unimplemented agreements tied to surrounding code, and fact-investigation materials. - Use Case: After a context-recomposition pass flags agreements without verifiable sources, run this Skill to walk through each one with the user and confirm concrete verification targets like src/services/checkin_tier_service.py:collect_and_assemble. ## Quick Start Ask the AI to set up anchors for the listed decisions, saying something like "create anchors for these agreements" or invoke /setup-anchor directly.
