What this skill does
Hex Local Dev Loop Overview Set up a development workflow for Hex API orchestration with mocked API responses and testing. Instructions Step 1: Project Structure Step 2: Typed Hex Client Step 3: Mocked Tests Prerequisites A mock or sandbox endpoint, safe project fixture, no production token in source/history/test output, and a fixture-reset command. A parameter/data-minimization assertion plus a change record and rollback path for future promotion. Output Return a local-loop receipt with fixture revision, environment, project scope, test totals, aggregate assertion outcome, temporary credential reference, and cleanup state. Exclude SQL, output, tokens, and identities. Error Handling Stop on production destination, missing data-minimization assertion, unbounded fixture, or failed cleanup. Do not use production output as a fallback test fixture. Examples fixtures=v7; mode=mock->sandbox; project=proj-dev-1; tests=12/12; assertions=pass; cleanup=complete is a safe promotion candidate. Resources Hex API Next Steps See hex-sdk-patterns for production patterns.
