What problem does it solve? Recording amendments to a governed livespec specification requires a structured, reviewable artifact rather than ad-hoc edits. This Skill files a proposed change under <spec-root>/proposed_changes/<topic>.md so the next revise pass can formally accept or reject it. ## Core Features & Use Cases - Structured change filing: Invokes the config-named propose-change CLI to write a proposed-change markdown file with findings, author, and optional spec target. - Core prose delegation: Resolves the livespec core root via the shared resolver script and executes core's harness-neutral propose-change prose end-to-end. - Guarded mutation: Enforces the footgun-guard extension precondition before any mutating operation runs, surfacing pi project-trust gate failures instead of proceeding unguarded. - Use Case: While reviewing a governed spec you notice a requirement gap; invoke this Skill to record the amendment as a proposed change that the next revise pass will adjudicate. ## Quick Start Ask the agent to file a proposed change against the livespec specification for a given topic, providing your findings so it lands under proposed_changes for the next revise pass.
