Install Casa
Getting started

Start with your own company files.

Install Casa, open a project, and let the first session establish the company context.

Reviewed September 16, 2026 · Casa v0.3.0 · Current Launchpad mainnet presets. Release notes

Before you start

  • Use Node.js 20 or later.
  • Have an agent harness and its model access ready; Casa does not supply a model subscription.
  • Open the company project you want Casa to work in. Keep private inputs and signing keys out of public repositories.
Claude Code: install, then run the skillsh
/plugin marketplace add https://github.com/Capx-AI/casa/plugin install capx-casa/casa-start

In an empty project, casa-start interviews you about the business. In an existing project, it first scans the available context. Review the profile and the proposed plan. A first session creates context; it does not instantly complete a company or all Phase 0 deliverables.

Other harnesses

Clone and identify the checkoutsh
git clone https://github.com/Capx-AI/casaexport CASA_ROOT="/absolute/path/to/casa"

Set CASA_ROOT to the real absolute path to your clone. In your project, instruct the agent to read $CASA_ROOT/AGENTS.md and follow $CASA_ROOT/skills/casa-start/SKILL.md. A clone alone does not install native slash commands in every harness.

Open the next session

These are harness skills, not shell executables. Casa reads the brain, proposes eligible work, produces an artifact, reviews it and records progress. Approve consequential actions only after inspecting the proposed output.

CASA / ILLUSTRATIVE SESSIONRead. Route. Make. Review. Record.
  1. /casa-next

    Read current state

    The local brain supplies the profile, constraint and eligible work.

  2. OPERATOR

    Produce an artifact

    A specialist works to a playbook's deliverables and review rubric.

  3. REVIEW + GATE

    Resolve findings

    Critics check the output. Obtain approval for actions that require it.

  4. RECORD

    Continue from files

    Update artifacts, state and the append-only ledger. Connected publication follows the configured integration.

Illustrative workflow, not a live customer transcript. /casa-next is a harness skill, not a shell executable.
