Open-source autonomous agent inside VS Code. Plan mode first, then act — with approval on every step.
Cline is a VS Code extension that reads and writes files, runs terminal commands and drives a browser, asking for approval at each step. It separates a planning mode from an acting mode so you can agree on the approach before any file changes. It is model-agnostic and supports MCP servers for extending what the agent can reach.
Provider-agnostic, including local models via OpenRouter/Ollama
Working inside VS Code on changes you want to see approved step by step rather than in one big diff.

Every tool here reads a project instruction file, and every one of them does better work when that file is accurate. The free Foundations track covers writing one; the Agent Operating Kit is the templates already written.
