Included Skills7

behavior-contractskills/behavior-contract/SKILL.md

Convert solution narratives into BDD feature files and protocol contracts. Use when translating user stories into testable specifications and API/event/RPC definitions. Consumes output from solution-narrative skill, produces artifacts consumed by architecture skills.

certificationskills/certification/SKILL.md

Verify traceability and produce evidence that implementation fulfills declared intent, published through the CI report rather than committed to the repo. Use after implementation and tests are complete, before merge. Cross-cuts all layers to close the chain from persona to proof.

domain-modelingskills/domain-modeling/SKILL.md

Define domain entities, value objects, aggregates, and business rules. Use when translating user stories into a formal domain model before creating API contracts. Bridges solution-narrative and behavior-contract skills.

e2e-journey-testingskills/e2e-journey-testing/SKILL.md

End-to-end test development from user journeys. Use when creating or updating e2e tests that validate user journeys. Consumes journey narratives and journey maps from specs/, produces Playwright tests in frontend.

idd-workflowskills/idd-workflow/SKILL.md

Meta-skill explaining when to use each development skill. Use when starting new work, onboarding, or unsure which skill applies to a task.

pr-reviewskills/pr-review/SKILL.md

Verify IDD compliance on pull requests. Use in CI/CD pipelines or manually before merge to check traceability, front-matter, capability scope, and spec-code alignment. Cross-cuts all layers like certification, but operates at PR-time on the diff.

solution-narrativeskills/solution-narrative/SKILL.md

User journey and story development. Use when capturing requirements, mapping user experiences, defining personas, or creating the narrative foundation that drives features and contracts. Output feeds into behavior-contract skill.
