atlante

Give form to your harness.

Website · Documentation · Packs

Define, test, evolve, and share your harness as code, with agents, skills, and evals in one structured system.

• Compose reusable presets and templates for agents and skills.
• Build deterministic OpenCode-native files with atlante build.
• Evaluate harnesses in OpenCode with versioned scenarios and atlante eval.
• Initialize projects from shared harness packs with atlante init --pack <your-pack>.

• No LLM inference or agent/skill execution.
• No project-code execution.
• No model, effort, permission, tool, or mode selection.
• No runtime-state, checkpoint, or scheduling management.
• OpenCode is the only supported host for now.
