Harness Installation

ORCA is harness-agnostic conceptually, but users still need concrete harness help.

What A Harness Is

A harness is the agent surface or host where ORCA commands, skills, and workflow rules are actually used.

Examples:

  • Codex
  • Claude Code
  • VS Code

Install Order

  1. Install ORCA first.
  2. Choose the harness in harness-chooser.md.
  3. Follow host setup in harness-setup.md.
  4. Verify with install-validation.md.

Core Rule

Do not force harness setup into the minimum ORCA install if the user is still deciding what host they want.
