Using Claude Code

Claude Code is the recommended AI assistant for Spec Kit. After initialization:

# Initialize
specify init my-project --ai claude

# Open in Claude Code
cd my-project
claude

# Commands are available immediately
/speckit.constitution ...
/speckit.specify ...

Using Other Agents

Each agent gets its commands installed in the appropriate location:

# Cursor
specify init my-project --ai cursor-agent

# Gemini CLI
specify init my-project --ai gemini

# Windsurf
specify init my-project --ai windsurf

Generic / Bring Your Own Agent

For agents not in the list, use the generic option with a custom commands directory:

specify init my-project --ai generic --ai-commands-dir .myagent/commands/

The CLI copies command templates to your specified directory. Your agent needs to support reading Markdown command files from that path.

Agent Limitations

Agent	Limitation
Amazon Q CLI	Does not support custom arguments for slash commands. Commands work but cannot pass inline prompts.

Switching Agents

To add support for a different agent to an existing project:

specify init . --force --ai gemini

This merges the new agent's configuration without overwriting existing specs.
