What this skill does
Hex Project Orchestration Overview Trigger Hex project runs from external orchestration tools (Airflow, Dagster, cron) with input parameters, status polling, and error handling. This is the primary integration pattern for embedding Hex in data pipelines. Instructions Step 1: Parameterized Project Runs Step 2: Synchronous Run Helper Step 3: Pipeline Orchestration Step 4: Cancel Long-Running Projects Error Handling Error Cause Solution ------- ------- ---------- 429 Too Many Requests Rate limit (20/min, 60/hr) Queue runs with delays Run ERRORED Project code failed Check project logs in Hex UI Run KILLED Timeout or manual cancel Increase timeout or fix slow queries 404 Project not published Publish project before triggering runs Prerequisites A named project owner, environment allowlist, approved parameter schema, and a sandbox project with fictitious or approved test data. Execution/cancel authority scoped to one project, a correlation convention, and a rollback or cancel procedure. Output Return an orchestration receipt with opaque project/run IDs, parameter revision, trigger identity class, start/terminal state, aggregate assertions, cancellation result, and rollback reference. Do not store SQL, cell output, or credentials. Examples project=proj-sandbox-12; params=r3; trigger=ci-service; run=complete; assertions=pass; cancel=not-needed; rollback=run-r5 records a controlled project run.
