What problem does it solve? Tags in the CALM memory system carry standing notes that are automatically injected into AI sessions, but editing them safely requires content-type judgment, length limits, and demotion of oversized sections. This Skill guides the review and update of tag notes so only durable lessons and environment knowledge are stored. ## Core Features & Use Cases - Notes Review: Search a tag with search_tags and inspect its current notes before editing. - Content-Type Judgment: Classify new content as lessons, pitfalls, or environment knowledge, keeping spec snapshots and procedures as one-line pointers. - Capacity Management: Demote oversized sections to materials with demote_tag_notes when notes approach the 4,000-character ceiling, then write the full updated text via update_tag. - Use Case: When a user says "update the notes for the api-design tag", the Skill drafts merged content, confirms it with the user, and writes it back while respecting suppression markers and length rules. ## Quick Start Show me the notes for the backend tag and append a lesson about retry handling.
