KitPilot

An agentic coding assistant for VS Code, powered exclusively by GitHub Copilot.

KitPilot is a streamlined fork of Roo Code, purpose-built for users whose organizations only authorize GitHub Copilot. Every non-Copilot AI provider integration has been removed; the extension routes all model traffic through VS Code's Language Model API — meaning if you have Copilot, you're already set up.

Why KitPilot

Most agentic coding extensions ship with 20+ provider integrations (Anthropic, OpenAI, Bedrock, Vertex, Gemini, Mistral, …). For a Copilot-only user, that flexibility is dead weight: extra dependencies, larger system prompts, more tokens spent per request, and a long settings page full of options you can't use.

KitPilot strips all of that out:

One provider, by design. Only vscode-lm (Copilot). No third-party SDKs, no API key prompts.
Smaller install. ~50 npm packages removed vs. the upstream extension; bundle is leaner.
Lower token cost per turn. Delta-only environment injection and trimmed-history sends mean roughly 3× fewer tokens vs. base Roo Code for the same conversation.
Same agent depth. Full multi-mode chat, tool use, MCP, custom modes — all of it works through Copilot.

What Can KitPilot Do For You

Generate code from natural-language descriptions
Refactor and debug existing code across multiple files
Adapt to your workflow with modes: Code, Architect, Ask, Debug, Orchestrator, or your own custom mode
Write and update documentation
Answer questions about your codebase
Execute terminal commands and consume their output as context
Talk to MCP servers for resources, tools, and prompts

Modes

Code Mode — everyday coding, edits, and file ops
Architect Mode — plan systems, write specs, design migrations
Ask Mode — fast answers, explanations, and docs
Debug Mode — trace issues, add logs, isolate root causes
Orchestrator Mode — break work into delegated subtasks
Custom Modes — build specialized modes for your team or workflow

Code Indexing (Optional)

Semantic codebase_search is supported via local Ollama embeddings. No external API keys required. Install Ollama, pull an embedding model (e.g. nomic-embed-text), and point KitPilot at it in settings. Indexing is off by default — KitPilot works without it, falling back to grep and file listings.

Requirements

VS Code 1.84 or later
An active GitHub Copilot subscription
(Optional, for semantic search) Local Ollama install

Credits

KitPilot is a fork of Roo Code, which itself is a fork of Cline. Both projects deserve the credit for the underlying agent design, mode system, and tool architecture. This fork's contribution is the Copilot-only narrowing, the token-efficiency work, and the rebrand.
