What problem does it solve? Building structured artifacts (workflows, node graphs, pages, multi-step generation pipelines) in one shot often produces results that drift from the intent and require costly rework. This Skill enforces a disciplined Spec → Gate → Build → Verify loop so every artifact is validated against a written contract before and after construction. ## Core Features & Use Cases - Spec-first authoring: Write a compact JSON spec with goals, constraints, and explicit out-of-scope items before any building begins. - Gate validation: Validate the spec (e.g., workflow catalog checks, prompt anchors, cost estimates) and refuse to build until it passes. - Deterministic multi-pass builds: Split construction into small idempotent passes where code handles structure and the model only decides content. - Verification loop: Diff each pass against the spec with cheap pre-filters first, spending model tokens only on judgment calls. - Use Case: When generating a 12-node image-generation workflow, author the node/edge spec, run the validator to zero errors, build each node group as a separate pass, then verify the rendered output matches the spec before declaring completion. ## Quick Start Ask the AI to build your workflow or page using the spec-gate-build pattern: write the JSON spec first, gate-validate it, build in deterministic passes, and verify against the spec.
