dag

DE//AGENT currently lists 5 resources under dag: 3 tutorials, 1 skill, 1 template. Everything below is derived from the live registry — counts, capabilities, verification state and security posture come from the curated records, never from marketing copy.

Documented learning objectives across these resources:

• Make every task safe to re-run — via Airflow DAG Reviewer
• Choose retries and timeouts deliberately — via Airflow DAG Reviewer
• Predict what a backfill will do before running it — via Airflow DAG Reviewer
• Apply the idempotency test to every task in a DAG — via Review a DAG for idempotency and retry safety
• Justify retry, timeout and concurrency settings per task — via Review a DAG for idempotency and retry safety
• Scaffold a DAG project with tests and a Dockerfile from the template — via Scaffold an idempotent DAG from the template
• Write tasks that are safe to re-run from day one — via Scaffold an idempotent DAG from the template
• Set catchup, retries and sensor modes as deliberate choices — via Scaffold an idempotent DAG from the template

3 more objectives live on the individual resource pages.

These resources map to stage: Orchestration (5). Follow the four-phase roadmap to place this topic inside a progression instead of learning it in isolation.

Every entry, its shape and its trust state — sorted by the registry's composite score. This table is the honest version of a marketing comparison: no sponsored placements, no unverifiable claims.

How scores are computed: source quality score.

Highest composite score first:

1. Airflow DAG Reviewer score 39.5 — intermediate
2. Review a DAG for idempotency and retry safety score 34.15 — beginner
3. Scaffold an idempotent DAG from the template score 34.15 — beginner

Scores rank provenance, completeness and trust — read how verification works before adopting anything.

Start here if you're new: Review a DAG for idempotency and retry safety, Scaffold an idempotent DAG from the template.

Security-flagged entries: Airflow DAG Reviewer (1 flag), Airflow DAG Template (4 flags). Flags mean the record declares capabilities like credential use or write access — read the security posture on each page before connecting.

• Airflow DAG Reviewer — Checks a DAG for non-idempotent tasks, unsafe retries, missing catchup policy, ambiguous catchup/backfill semantics and unbounded concurrency. details
• Review a DAG for idempotency and retry safety — Walk the Pipeline Reviewer's four-step pass over a DAG: apply the idempotency test to every task, check retry, timeout and concurrency settings, predict backfill behaviour, and pro… details
• Scaffold an idempotent DAG from the template — Generate a new pipeline from the Airflow DAG template and keep its guarantees — an idempotent skeleton with task groups, retries and backoff, SLA, pools, and a reschedule-mode sens… details
• Wire task dependencies and retries that survive failure — Model the pipeline as task groups and give every task deliberate retries with backoff, a timeout and a pool — the skeleton's guarantees, verified the way the DAG reviewer verifies … details
