VSCode Extension
Blinky provides an open-source debugging agent inside Visual Studio Code to help developers inspect code issues.
About VSCode Extension
Blinky is an AI debugging agent extension for Visual Studio Code. It uses large language models to help identify and fix backend code errors. The project is described as open-source and inspired by SWE-agent, using the VS Code API, Language Server Protocol, and print-statement debugging to locate bugs in backend systems.
To use it, you install the extension from the VS Code marketplace and open the chat interface from the sidebar icon. You describe the bug in the chat box and can optionally add reproduction steps to give the agent access to runtime behavior. While the agent runs, you can provide feedback that is used in later steps. When finished, the extension shows the proposed edits in an interface where you can accept or reject the changes.
Blinky suits developers working on backend code in VS Code who want agent assistance with debugging. A first run prompts for an OpenAI API key, which is stored locally in the VS Code configuration for later calls to OpenAI's servers.
