GEPA Loop Drives Automatic Skill Evolution

Hermes Agent from Nous Research self-improves by pausing every 15 tool calls to analyze outcomes using GEPA (Generate-Execute-Prompt-Adapt), mimicking backpropagation for prompts instead of weights. It identifies failures, updates behaviors, and creates reusable skills from successes, errors, or user instructions—persistent across sessions without manual fine-tuning or prompt engineering. This builds a memory system referencing past conversations, adapting to user workflows like preferring Shadcn packages for UI tasks. Result: Agents handle complex tasks like animating technical concepts with Manim or generating thumbnails autonomously, outperforming static agents over repeated use.

Unlike OpenClaw's focus on broad ecosystem control, Hermes prioritizes depth through reflection and evolution, while supporting identical capabilities: local models, tool integrations (Firecrawl, Exa), and multi-platform access via Telegram, WhatsApp, or Slack.

Local Setup with Gemma4 for Zero-Cost Runs

Install via single terminal command on macOS/Linux (WSL2 for Windows): clone repo, pip install. Run hermes setup for quick config (model provider + messaging) or full setup. Use Ollama Gemma4 locally if hardware supports (check whatmodelscanirun.com)—agentic model excels here without API costs. Free OpenRouter models work as fallback. Add tool APIs (e.g., Firecrawl for scraping) during setup. Gateway enables phone control. Post-setup, chat interface lists tools; /skills browses/adds skills like Obsidian for knowledge graphs.

Skills Build Frontend Dashboards from Docs

Demonstrate by adding Obsidian skill: Hermes creates vault, scrapes Shadcn docs for latest packages (e.g., interlinking components), stores as reference graph. Next task—"build finance dashboard using Shadcn"—leverages this memory: generates modern React UI with updated components in minutes. Memory persists user preferences (e.g., Shadcn over alternatives), improving future outputs. Other examples: image gen for 8 thumbnails from prompt; visual explanations of math/algorithms via auto-created Manim skill. Trade-off: Relies on tool quality (e.g., free models yield basic thumbnails).
