Hermes IDE
AI superpowers for
your shell
Hermes wraps your existing shell — zsh, bash, fish — and adds ghost-text completions, autonomous task execution, project awareness, and error memory. 100% free, forever.
npm install --legacy-peer-depsEverything you need, nothing you don't
Six powerful features layered on top of the shell you already know and love.
Ghost-text Suggestions
Real-time, context-aware command completions that appear as you type. Accept with Cmd+Tab.
Prompt Composer
Describe what you want in natural language. Hermes translates it into autonomous task execution.
Project Realms
Auto-scans your project for languages, frameworks, and architecture. Context is always up to date.
Error Memory
Learns from error patterns you've encountered before. Auto-applies known fixes when they recur.
Execution Timeline
Visual command history with exit codes, durations, and output. Navigate with a glance.
Cost Dashboard
Track token usage and costs per model and session. Stay in control of your AI spend.
Compose prompts, not commands
The Prompt Composer lets you describe complex tasks in natural language. Pick roles, set styles, define scope — and Hermes compiles it into a precise prompt sent straight to your AI agent.
- Choose from built-in roles or create your own
- Set style presets: concise, step-by-step, verbose
- Define task scope to focus on specific files or directories
- Save templates for recurring workflows
- Live preview shows the compiled prompt in real-time
- Send directly to your terminal session with ⌘↵
## Role You are a Senior Engineer and DevOps specialist. ## Style Be concise and direct. Provide step-by-step instructions when needed. ## Task Refactor the authentication module to use JWT tokens instead of session cookies. Ensure backward compatibility with existing API clients. ## Scope Focus on src/auth/ and src/middleware/. Don't touch test files. ## Constraints - No new dependencies - Keep backward compat with v2 API
