Hermes Agent

oh-my-hermes is an intelligence harness and workflow orchestration layer built on top of NousResearch's Hermes Agent, adding mixture-of-models routing, memory systems, and structured multi-agent workflows. It transforms standard Hermes requests into governed, evidence-tracked execution paths with parallel processing, phase-structured planning, and explicit verification boundaries. Developers install it via Homebrew, Bun, or npm to gain access to eight ultra-workflows (ulw-context, ulw-interview, ulw-research, ulw-plan, ulw-work, ulw-loop, ulw-qa, ulw-perf) that handle everything from requirement clarification to performance optimization. The system routes different task categories to appropriate models with configurable reasoning effort, maintains transparent execution evidence, and provides a rich terminal UI showing real-time delegation, costs, and progress.

Key Features

Mixture-of-models routing with editable category chains (ultrabrain, deep, quick, writing, visual-engineering) that dispatch tasks to optimal model+reasoning-effort combinations
Eight structured ultra-workflows covering interview, research, planning, parallel work execution, iterative loops, QA testing, and performance optimization
Evidence-bound execution tracking that distinguishes prepared intent, running activity, reported completion, and verified outcomes
Parallel work lanes with isolated file ownership, concurrent tool calling, and independent verification subagents
Phase-structured TODO system that declares work as reviewable checklists before execution begins
Rich terminal HUD displaying live delegation rows with category, model, turn count, cost, cache metrics, and parallel batch indicators
One-command setup (omh setup) that installs workflows, registers with Hermes, and guides model configuration
Context intelligence for compact repository understanding and just-in-time learning without hidden memory layers

Use Cases

  • 01Orchestrating complex software development tasks across multiple models with different capabilities and cost profiles
  • 02Running parallel code implementation lanes that never conflict on file ownership while tracking progress independently
  • 03Conducting thorough research with source tracking and verification before making architectural decisions
  • 04Building and iterating on plans with explicit review gates, risk assessment, and done-criteria agreement
  • 05Executing QA workflows that attack builds with hostile scenarios and fix failures in verified cycles
  • 06Optimizing performance by measuring actual bottlenecks and fixing hot paths with evidence of improvement

oh-my-hermes — FAQ

What is oh-my-hermes?+

oh-my-hermes is an agent engineering harness that sits above Hermes Agent, adding workflow orchestration, mixture-of-models routing, structured planning, parallel execution, and evidence-tracked verification. It enhances Hermes with professional operating capabilities while keeping Hermes as the natural-language interface.

How do I install oh-my-hermes?+

Install via Homebrew (brew install rlaope/tap/omh), Bun (bun install -g oh-my-hermes), npm (npm install -g oh-my-hermes), or the universal installer (curl -fsSL https://raw.githubusercontent.com/rlaope/oh-my-hermes/main/install.sh | sh). After installation, run 'omh setup' to configure workflows and connect to Hermes.

Which AI clients does oh-my-hermes work with?+

oh-my-hermes integrates exclusively with Hermes Agent (by NousResearch). It provides Desktop, CLI, and messenger app interfaces for Hermes, and routes work across multiple model providers (GPT, Claude, DeepSeek, Kimi, GLM, Gemini, Qwen) based on task categories.

Do I need API keys or prerequisites?+

You need a working Hermes Agent installation and API credentials for the model providers you want to use (OpenAI, Anthropic, DeepSeek, Moonshot/Kimi, GLM, Google, etc.). During 'omh setup', the guided model configuration helps you select and configure active providers.

Is oh-my-hermes free to use?+

Yes, oh-my-hermes is open-source and free to install and use. However, you'll incur costs from the underlying model providers (OpenAI, Anthropic, etc.) based on your usage. The HUD displays real-time cost tracking for each operation.

How do I update oh-my-hermes?+

Run 'omh update' which auto-detects your installation method and upgrades through the original installer (Homebrew, Bun, npm, or curl), then refreshes managed skills and Hermes registration. Use 'omh doctor' to verify the installation afterward.

How do I install oh-my-hermes?+

Open the source repository on GitHub and follow its README. oh-my-hermes is a agent — MCP Agents Market links you directly to the official repo.

Is oh-my-hermes free?+

oh-my-hermes is an open-source project hosted on GitHub. Check the repository for its license and any usage requirements.
