The Support Buddy X9000 is a fully agentic support engineering platform designed to transform how support teams handle incoming tickets. Rather than relying on manual triage and investigation, the platform uses a 9-node LangGraph pipeline to autonomously investigate each ticket — gathering evidence from logs, documentation, and past incidents in parallel.

Once the investigation is complete and a root cause has been identified and ranked, the system presents its findings to a human reviewer. With approval, it hands the validated issue off to Devin AI, which autonomously reproduces the bug, writes a fix, runs tests, and opens a pull request.

The entire workflow is orchestrated through Inngest for reliable async execution, with full audit trails, GitHub issue synchronization, and incident clustering to catch recurring patterns before they escalate.

Key Features

9-Node Investigation Pipeline

A LangGraph-powered pipeline that parallelizes evidence gathering across logs, documentation, and historical incidents, then ranks potential root causes by confidence score.

9-Node Investigation Pipeline

Human-in-the-Loop Approval

Every autonomous action is gated by human approval. The system presents investigation findings with evidence before requesting permission to proceed with automated fixes.

Devin AI Coding Integration

Validated issues are handed to Devin AI, which autonomously reproduces bugs, writes fixes, runs the test suite, and opens pull requests — all without manual intervention.

Inngest Async Orchestration

Inngest handles all background job execution with built-in retries, rate limiting, and observability, ensuring the pipeline remains reliable at scale.
