Agent Triages a Flaky Test and Drafts a Root-Cause Hypothesis

What it does

Turns a bare "this test is flaky" ticket into an actionable investigation. An agent reads the failure logs, stack trace, and the recent commits touching the test, then categorizes the most probable cause and drafts a concrete fix suggestion — so the assigned engineer starts with a hypothesis instead of a blank page.

When to use it

Use it when flaky-test tickets pile up uninvestigated because triage is tedious. This front-loads the diagnostic work the moment a flake is filed.

How it works

  1. 1A new Linear issue tagged `flaky-test` triggers the workflow.
  2. 2An action fetches the failing GitHub Actions job logs and stack trace.
  3. 3An action pulls the recent commits and diffs touching the test file.
  4. 4An agent reasons over logs and diffs to classify the flake (timing, test ordering, network, shared fixture) and drafts a root-cause hypothesis with a suggested fix.
  5. 5An output posts the analysis as a comment on the Linear issue and assigns a confidence label.

Set it up

What you configure once, before turning it on.

  1. 1
    Connect LinearIssues, projects, cycles, triage.
  2. 2
    Connect GitHubRepos, issues, pull requests, actions.
  3. 3
    Connect OpenAIModels, embeddings, files.
  4. 4
    Set each agent's modelWe leave models unset so you pick the tier — fast + cheap, or top-quality.
  5. 5
    Tune it to your dataEdit the prompts, filters, and field mappings so it matches how your team works.
  6. 6
    Test, then turn it onRun once against a sample, confirm the output, then enable the trigger.
