What problem does it solve? After running an implementation pass, teams often cannot tell whether the code actually satisfies everything the spec, plan, and tasks demanded. This Skill closes that gap by auditing the current codebase against the feature's spec.md, plan.md, and tasks.md, then appending any unbuilt or incomplete work as new traceable tasks so the implement step can finish the job. ## Core Features & Use Cases - Gap Assessment: Builds an intent inventory from functional requirements, success criteria, acceptance scenarios, plan decisions, and constitution principles, then classifies each finding as missing, partial, contradicts, or unrequested. - Severity Grading: Ranks findings CRITICAL through LOW, with constitution MUST violations treated as the highest severity. - Append-Only Task Generation: Appends a new numbered Convergence phase to tasks.md with zero-padded task IDs, never rewriting or renumbering existing tasks. - Extension Hooks: Supports optional and mandatory before_converge and after_converge hooks declared in .specify/extensions.yml. - Use Case: After /speckit-implement finishes, run this Skill to verify FR-008 is actually enforced in code; if not, a new task like "T042 Add append-only enforcement per FR-008 (missing)" is appended for the next implement pass. ## Quick Start Ask the agent to run the speckit-converge skill to check the current codebase against the feature spec and append any remaining work to tasks.md.
