Hi HN. I'm the founder of Phoenix Labs (ex TikTok, Applied AI) and we're open sourcing our internal tooling today which is like a toolchain / meta-harness for CLI agents useful for really scaling eng and creative work. We are a very small team who's building a very ambitious product so we had to find ways to squeeze every ounce of efficiency that we could get our hands on. Harness strengths of different models (Claude, GPTs) and CLI-harnesses (Claude Code, Codex), safe/robust browser integration to speed up UX/QA testing, teams cli to speed up security reviews and parallelize bug hunting and fixes, and secrets cli with touch id integration so DX is extremely fast. We also noticed that small things like installing marketplaces, or sharing resources per projects (skills, plugins, secrets, subagents, workflows, rules, permission groups, hooks) took a lot of time so we put everything under ~/.agents and supported multi-layer dot-agents repos, auto layering and syncing system, user and project level resources and extra so teams can have their own dot-agents repos Fun things like auto-rotation of CC credentials to tackle session limits also exist and save a lot of time. We usually have multiple agent versions installed per agent type. CLI is called `agents` and it injects shims for `claude`, `codex` and other agents. When we need a new feature like routines for keeping CI healthy, we just implement it in a way that's compatible with most commonly uses agent-harnesses at our company including Claude Code, Codex, Antigravity/Gemini, Cursor/Grok CLI and more Install: curl -fsSL agents-cli.sh/install.sh | sh # or: bun install -g @phnx-labs/agents-cli Source: https://github.com/phnx-labs/agents-cli Honest limits: macOS works best. Linux works. Touch ID is macOS only. But, it's MIT :) Want feedback on the developer experience. And my apologies if your agent harness is not supported throughout. Please feel free to make a PR and happy to hop on a chat/call Muqsit |
