Code Intelligence

Multi-Agent Support

Supports running multiple AI agents concurrently or orchestrating sub-agents to divide complex tasks into parallel workstreams.

Agent Support 41 of 47 (87%)

Multi-File Editing

Can read, create, and modify multiple files in a single operation. Essential for refactoring, adding features that span several modules, or generating boilerplate across a project.

Agent Support 46 of 47 (97%)

Integration & Connectivity

MCP Support

Supports the Model Context Protocol (MCP), an open standard for connecting AI agents to external tools, data sources, databases, and APIs through a unified interface.

Agent Support 43 of 47 (91%)

Hooks / Extensions

Supports lifecycle hooks or a plugin/extension system that lets you run custom scripts or commands at specific points during the agent's workflow.

Agent Support 39 of 47 (82%)

Web Search

Can search the web to find documentation, examples, and up-to-date information while working on your code. Helps the agent stay current beyond its training data.

Agent Support 41 of 47 (87%)

Local Model Support

Can run with locally hosted AI models (e.g. Ollama, llama.cpp) instead of cloud APIs. Enables fully offline, private development without sending code to external servers.

Agent Support 31 of 47 (65%)

Automation & Security

Auto Test Running

Automatically runs your test suite after making code changes and iterates on failures. The agent can detect test failures and fix them without manual intervention.

Agent Support 37 of 47 (78%)

Sandbox / Permissions

Runs commands in a sandboxed environment with configurable permissions. Prevents the agent from executing dangerous operations without explicit approval.

Agent Support 39 of 47 (82%)

Input & Context

Image / Multimodal Input

Accepts images, screenshots, and other visual input alongside text. Useful for UI work, debugging visual issues, or providing design mockups as context.

Agent Support 37 of 47 (78%)

Voice Mode

Supports voice input for dictating instructions or having a spoken conversation with the agent. Enables hands-free coding workflows.

Agent Support 9 of 47 (19%)
