What problem does it solve? When a user comments on a GitHub issue mid-implementation, someone must interpret the feedback, apply the code change, verify it compiles and passes tests, commit and push, and update the task checklist — all without prematurely advancing the automated pipeline. This Skill guides Claude Code through exactly that comment-review loop inside the Fabrik Implement stage. ## Core Features & Use Cases - Scoped change application: Reads .fabrik-context/issue.md and .fabrik-context/stage-Plan.md to understand the spec and current plan state, then makes only the minimal change the user requested. - Safe verification discipline: Enforces foreground, timeout-bounded verification (build commands, framework test timeouts) instead of backgrounding dev servers or CI waits that would orphan processes or silently end the stage. - Checklist and label management: Updates the Plan stage comment's task checkboxes via gh issue view, respects labels like fabrik:extend-turns and fabrik:tools-denied, and never emits FABRIK_STAGE_COMPLETE so the pipeline does not advance. - Use Case: A user comments "use the interface type instead of the concrete struct" on an in-progress issue; the Skill applies the change, runs the tests, commits with a message referencing the feedback, updates the plan checklist, and returns control to the engine. ## Quick Start Ask the agent to act as the Fabrik Implement comment reviewer and apply the user's latest comment on the current issue, then commit and push the change without signaling stage completion.
