Practical overview

When it fits

Use Evolver when an agent project needs structured, reusable records of experience and changes instead of ad hoc prompt adjustments.

Who it is for

  • Developers building AI agents
  • Researchers testing structured agent evolution
  • Teams that need auditable records of changes to agent behavior
  • Users working with CLI or self-hosted agent infrastructure

Documented uses

  • Build and evolve AI agents
  • Record changes as Genes, Capsules, and Events
  • Inspect or manage agent-evolution artifacts through a CLI
  • Track changes to LLM-agent behavior with an audit trail
  • Experiment with protocol-oriented agent evolution
Before you choose

Requirements & limits

The repository is public and listed as open source. The documented setup requires Node.js 18 or newer and Git; the primary CLI workflow runs inside a Git-initialized project directory.

  • Git is required for the documented CLI workflow, including rollback-related operations.
  • The framework models evolution with Genes, Capsules, and Events, which distinguishes it from workflows based only on prompt or skill-document changes.
  • The repository lists GPL-3.0, while its README also describes a planned transition from fully open source to source-available for future releases.
  • A contributor-oriented run-from-source path is documented separately from the recommended CLI quick start.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install Evolver and prepare a project

Set up the Evolver CLI in a Git-based project.

Before you start

  • Node.js 18 or newer
  • Git
  • A Git-initialized project directory

Steps

  1. Install the CLI with npm: npm install -g @evomap/evolver.

  2. Verify that the command is available with evolver --help.

  3. Change to a Git-initialized project directory before running Evolver.

Expected outcome

The Evolver CLI is installed and the project meets the documented prerequisites for use.

Guide limitations

  • The supplied documentation covers installation and prerequisites but does not document a complete agent-evolution run.
  • Running Evolver in a non-Git directory will fail with a clear error message.
