Give form to your harness

Atlante is the configuration and build layer for your coding-agent harness. It turns agents, skills, and workflows into one versioned system in your repository, then materializes that system through a host adapter.

The authored source is a JSONC configuration document. Atlante validates the document and its selected content, renders deterministic Markdown, and publishes verified artifacts under .atlante/artifacts/.

Note

Atlante v0.1 supports OpenCode as its host adapter. Atlante does not execute agents, skills, project code, or LLM inference.

Start with the source

A project normally contains one atlante.jsonc file. It selects a preset, binds agents and skills to templates or instances, and provides the values those bindings need.

atlante.jsonc

{
  "$schema": "https://atlante.sh/schema/v0.1/schema.json",
  "extends": "@atlante/pack",
  "values": {
    "project": "my-app"
  }
}

Run npx @atlante/cli init to scaffold this starting point. Continue with the installation guide, or read your first build for the complete source-to-artifact path.

The system boundary

Atlante owns configuration, static content selection, validation, composition, interpolation, rendering, and artifact publication. The host adapter owns materialization into a host configuration, while the host and prompted model own execution.

This separation keeps the authored system reviewable in Git and keeps generated output independent from host settings.

Documentation map

• Start here explains installation and the first build.
• Concepts explains documents, packs, templates, values, resolution, and artifacts.
• Guides shows how to build a harness, author a pack, use OpenCode, and watch for changes.
• Reference records the CLI, configuration fields, artifact format, diagnostics, and schema.

If a page and the implementation differ, the shipped implementation, tests, and SPECIFICATION.md are the authoritative sources for v0.1 behavior.
