## What the Jenkins integration adds

Jenkins brings build evidence from your own CI environment into Unblocked’s failure-analysis workflow. That evidence is evaluated with the connected repository and pull request so the resulting report reflects the change under review, not only an isolated log line.

Because Unblocked already understands your codebase, pull requests, and team discussions, its analysis is grounded in that context — it explains what broke and suggests a fix, with links back to the relevant code and history.

Jenkins connects to your own server through the Unblocked Jenkins plugin and a personal access token. Reports post as a comment on the pull request and are gated by confidence.

### What you get

- **Automatic failure analysis** — The CI Failure Agent analyzes failed Jenkins builds to find the root cause — no manual log-digging.
- **Root-cause reports on the PR** — When confident, Unblocked posts a comment on the pull request explaining the failure and suggesting a fix.
- **Runs against your own server** — The Unblocked Jenkins plugin connects to your self-hosted Jenkins instance, with IP-range allowlisting for network-restricted servers.
- **Confidence-gated, per-developer control** — Reports post only when Unblocked is highly confident, and each developer can toggle them for their own PRs in Personal Settings → Preferences.

## Jenkins failures the agent can analyze

Examples of Jenkins failures the CI Failure Agent can investigate:

- "Why did the Jenkins build fail on this pull request?"
- "What is the root cause of the failing stage in CI?"
- "Which recent change most likely caused the build failure?"
