# OpenFiles > OpenFiles is a VS Code extension that opens every file an AI coding agent edits, so VS Code's linters and type checkers run on it, lists the changes for review, and hands the problems back to the agent through hooks. - Install from the VS Code Marketplace (`devgiordane.openfiles`) or Open VSX for Cursor, Windsurf, VSCodium, Antigravity and Kiro. - Agents read problems from `.openfiles/diagnostics.json` in the workspace. The format is in the diagnostics file reference. - Hook configuration is installed by the user through the "OpenFiles: Install Agent Hooks…" command, which shows a preview. Agents should not write hook config themselves. ## Documentation Sets - [Abridged documentation](https://devgiordane.github.io/openfiles/llms-small.txt): a compact version of the documentation for OpenFiles, with non-essential content removed - [Complete documentation](https://devgiordane.github.io/openfiles/llms-full.txt): the full documentation for OpenFiles ## Notes - The complete documentation includes all content from the official documentation - The content is automatically generated from the same source as the official documentation
