Apache Airflow

DE//AGENT currently lists 4 resources under Apache Airflow: 3 skills, 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
• Scope a backfill by date and by dependency — via Backfill Planner
• Detect which downstream tables must also be rebuilt — via Backfill Planner
• Stage a backfill gradually with validation between batches — via Backfill Planner
• Write a blameless timeline — via Incident Postmortem Writer
• Separate trigger from contributing factors — via Incident Postmortem Writer

1 more objectives live on the individual resource pages.

These resources map to stages: Reliability (1), Orchestration (3). 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. Backfill Planner score 39.5 — advanced
3. Incident Postmortem Writer score 38.9 — beginner

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

Start here if you're new: Incident Postmortem Writer.

Reach for these with production experience: Backfill Planner.

Security-flagged entries: Airflow DAG Reviewer (1 flag), Backfill Planner (1 flag), Incident Postmortem Writer (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
• Backfill Planner — Produces a backfill plan: date ranges, blast radius, resource contention, idempotency check, validation gates and rollback. details
• Incident Postmortem Writer — Structures incident notes into a blameless postmortem: timeline, impact, detection gap, contributing factors, and action items with owners and dates. details
• Airflow DAG Template — An idempotent DAG skeleton with task groups, retries and backoff, SLA, pools, and a sensor using reschedule mode. details
