Agent-Driven dbt Failure Triage and Root-Cause Brief

On a dbt failure it spins up an agent that reads the error, inspects upstream source freshness and recent model changes in GitHub.

How it runs

The automated pipeline, trigger to output.

  • Triggerdbt failure posts to webhookHTTP webhook
  • ActionCheck upstream source freshness in SnowflakeSnowflakeSnowflake
  • ActionReview recent model commits and PRs in GitHubGitHubGitHub
  • LogicAgent drafts root-cause hypothesis and owner
  • ActionWrite incident brief to NotionNotionNotion
  • OutputPing likely owner in Slack with linkSlack

What it does

Goes beyond alerting to first-pass triage. An agent gathers the failure log, checks whether an upstream source was stale, scans the model's recent commits, and produces a short root-cause hypothesis plus a suggested owner, written into a structured incident doc.

When to use it

Use it when dbt failures are ambiguous and on-call burns time figuring out whether it was bad source data, a schema change, or a code regression. The agent does the boring correlation work before a human reads it.

How it works

  1. 1A dbt failure webhook starts the flow with the failed model and error.
  2. 2The agent queries Snowflake to check upstream source freshness at the time of failure.
  3. 3It reviews the model's recent GitHub commits and PRs for relevant changes.
  4. 4It reasons over the evidence to draft a root-cause hypothesis and identify the likely owner.
  5. 5It writes the brief to a Notion incident page and pings that owner in Slack with the link.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect HTTP webhookTrigger any URL on agent actions.
  2. 2
    Connect SnowflakeWarehouses, queries, shares.
  3. 3
    Connect GitHubRepos, issues, pull requests, actions.
  4. 4
    Connect NotionPages, databases, comments.
  5. 5
    Connect SlackChannels, DMs, threads, mentions.
  6. 6
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  7. 7
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  8. 8
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
