Ouroboros is an open-source autonomous CLI coding agent developed by razzant. Built primarily in Python, the agent is engineered to execute self-directed code modification loops, automate complex engineering tasks, and validate changes through structured preflight checks and review panels. In standard workflows, Ouroboros operates directly against a target repository worktree. It manages task planning, file edits, and multi-runtime test execution across Python and Node.js test suites. The agent uses configurable model backends (including Claude Sonnet variants) and enforces automated review cycles and task-acceptance verification before staging or committing modifications. What differentiates Ouroboros from basic interactive assistants is its focus on hermetic validation, process containment, and benchmark reproducibility. It incorporates strict commit gating with budget-capped test runs, a process container isolation layer to mitigate side effects, and native integration with benchmark evaluation suites like SWE-bench Pro, OSWorld, GAIA, and ProgramBench. Ouroboros is available as an open-source project hosted on GitHub, with ongoing maintenance centered around automated test gates, CI integration, and benchmark performance.
