Triss is a coworker for your coding agent, not another hosted platform.
Triss is an open-source command-line tool and MCP server (npm: triss-coworker) that lets coding agents such as Claude Code and Codex delegate work — codebase research, code review, and implementation tasks — to the model providers and coding engines you choose. It runs locally, keeps its state on your machine, and reports every result with the evidence and usage data you need to accept or reject it.
What the project optimizes for.
Providers, models, and coding engines are configuration, not ideology. Supported routes are documented, and restrictive defaults are avoided.
Triss is a CLI, not a hosted service. There is no developer telemetry, no control plane, and no account. Your credentials stay configured by you, for you.
A worktree separates delegated changes but is not a sandbox. A finished run is not acceptance. Triss says so on the tin — see the security and privacy page.
Findings, diffs, execution details, and token usage stay available for review. Delegation that cannot be audited is not delegation worth having.
How it is maintained.
Development happens in the open at github.com/ayleen/triss-coworker. The project is MIT-licensed, accepts contributions under the Developer Certificate of Origin, publishes releases with signed tags and npm provenance, and tracks its governance and roadmap in the repository (GOVERNANCE.md,MAINTAINERS.md). Install is one command:npm install -g triss-coworker. If you want to help, start with CONTRIBUTING.md.
