03 / DEVELOPER TOOLS / AUTONOMOUS AGENTS2026

Velo.

An agent that follows a failing pipeline all the way to a proposed fix.

01The problem

A failed CI/CD pipeline leaves developers manually tracing logs, reproducing failures, editing code, and rerunning tests.

02The system

An autonomous repair workflow that discovers tests, analyzes failures, proposes patches, retries execution, and opens a GitHub pull request, with progress streamed to the frontend.

03My contribution

Developer on team Vakratund, with Tejas Kumar Punyap (team lead) and Karan Mani Tripathi (developer). My work contributed to the hands-on implementation of the repair system.

04An engineering decision

Represent the debugging loop with a three-node LangGraph workflow. Keep test execution inside controlled environments and expose progress through server-sent events.
