Unblock PR

One-line summary: Investigate a failing PR CI pipeline — attribute each failure as flaky, infra, or regression and propose a targeted action.

Requires: dd-pup skill (pup CLI installed and authenticated), triage-flaky-test skill (for flaky failure deep investigation).

Backend

Detection — At the start of every invocation, before taking any action, determine which backend to use:

1. If the user passed --backend pup anywhere → use pup mode immediately. Skip steps 2–4.
2. Check whether search_datadog_ci_pipeline_events appears in your available tools.
3. If present → use MCP mode throughout. Call tools exactly as named in this skill's workflow sections.
4. If absent → check whether pup is executable: run pup --version via Bash. If the command exits successfully (exit code 0), pup is available.
5. If pup responds → use pup mode throughout. Translate every tool call using the Tool Reference appendix at the bottom of this file.
6. If neither is available → stop and tell the user:

   "Neither the Datadog MCP server nor the pup CLI is available. Connect the MCP server or install pup (brew install datadog-labs/pack/pup)."
