What problem does it solve? Teams using GitHub Copilot often lack a consistent way to turn an approved implementation plan into verified code changes. This Skill executes an authorized plan card by card, enforcing specification review, quality checks, and verification evidence so each build step stays traceable to the plan. ## Core Features & Use Cases - Card-by-card implementation: Executes the canonical Lintel build workflow for each authorized plan card rather than ad-hoc coding. - Spec and quality review: Applies the Copilot adapter contract's authorization and verification rules before and during implementation. - Verification evidence: Produces documented proof that changes meet the plan's acceptance criteria. - Use Case: After running /li-plan to generate build cards for a new health endpoint, a developer invokes this Skill so Copilot implements each card in order, checks it against the specification, and records verification results in the working repository. ## Quick Start Ask Copilot to run the li-build skill to implement the authorized plan cards for the current feature with spec review and verification evidence.
