What problem does it solve? Long working sessions establish conventions, measurements, and decisions that never appear in the shipped code or diff, so they are lost once the conversation ends. This Skill reads the session transcript on disk and turns what the thread settled into a durable skill, or an addition to an existing one. ## Core Features & Use Cases - Transcript harvesting: Locates the current session's JSONL transcript (including predecessors of resumed sessions), separates the person's turns from tool results, and pulls the passages where corrections were settled by measurement or decision. - Classification and sifting: Classifies each fact against an existing skill as new, sharpens, exception, contradicts, or covered, and drops project state, third-party behavior records, and person-specific statements. - Gated writing: Presents a numbered outline table for approval before writing, then hands the approved material to the skill-updating convention and runs the target repository's verification checks. - Use Case: After a long debugging session that established why a lockfile install ignores quarantine rules, run the skill to distill that finding into a convention skill instead of letting it vanish with the conversation. ## Quick Start Ask the agent to run /hos-skillify with an optional topic to turn what this conversation established into a skill.
