Core Features

Evolutionary Self-Improvement

Utilizes DSPy + GEPA to evolve and optimize Hermes Agent's skills, prompts, and code, producing better versions through reflective evolutionary search without GPU training.

Source: README
API-Based Operations

Operates via API calls for mutating text, evaluating results, and selecting the best variants, with a cost of ~$2-10 per optimization run.

Source: README
Phased Optimization

Planned phased optimization of skill files, tool descriptions, system prompts, code, and a continuous improvement loop.

Source: README

Architecture

The architecture is modular, with distinct components for skill evolution, tool description optimization, system prompt sections, code evolution, and a continuous improvement loop. It uses DSPy + GEPA for reflective prompt evolution and Darwinian Evolver for code evolution. The code is organized into a clear directory structure with separate modules for different functionalities.
