Flaky Test Detection Harness Agent Pack

Detect, root-cause, and quarantine flaky tests across your CI pipeline — then automatically create tracked fix issues so unreliable tests stop blocking good changes. Requires GitHub, Jira, and Slack connected to your agent.

A 4-step agentic workflow pack for coding built to run with Claude, ChatGPT, Claude Code, and Cursor. It drives an AI agent connected to GitHub, Jira, and Slack (for example via MCP), and still works without them — paste the relevant data in when the prompt asks. Most buyers get a reviewable result in about 15 minutes.

  • Surface nondeterministic test failures from CI history before they erode team trust in the pipeline
  • Get structured root-cause hypotheses — timing races, shared state, order dependencies — ranked by likelihood
  • Receive a clear quarantine vs fix recommendation with rationale for each identified flaky test
  • Automatically create and assign tracked fix issues in Jira so nothing falls through the cracks
  • Notify the owning team in Slack the moment a test is quarantined so they can act without waiting for retros
  • Degrade gracefully to paste-in mode when tools are unavailable — no silent failures

This pack is built to run inside an AI agent with GitHub, Jira, Slack connected (for example via MCP), which automates the workflow end to end. No connected tools? It still works — paste the relevant data in when the prompt asks.
What if I get stuck?
