VSCode Extension
Blinky is an open-source AI debugging agent that functions as a Visual Studio Code extension, harnessing the power of large language models (LLMs) to automate the identification and resolution of software bugs, particularly in backend systems. Inspired by the SWE-agent framework, Blinky provides a user-friendly chat interface within VSCode where developers can describe errors, optionally provide reproduction steps, and then watch as the agent autonomously explores the codebase, leveraging the VSCode API, Language Server Protocol, and dynamic print statement insertion to triangulate the root cause of issues. The agent iterates through potential fixes, incorporates real-time user feedback, and ultimately proposes changes that can be reviewed and accepted or rejected via a built-in diff viewer. Designed to accelerate the debugging workflow, Blinky aims to reduce the manual effort required to trace and fix bugs, making it a valuable tool for both solo developers and teams. Its open-source nature encourages community contributions and customization, while its integration with the widely-used VSCode editor ensures a low barrier to entry for most developers.

Problem solved
Software developers often spend a disproportionate amount of time manually debugging backend code, which involves sifting through logs, inserting print statements, and hypothesizing about failure causes. This process is tedious, error-prone, and can delay delivery timelines. Blinky addresses this by acting as an automated AI pair-debugger that uses LLMs to interpret bug reports, analyze source code, and execute runtime debugging steps. By offloading the repetitive parts of debugging to an agent, developers can focus on higher-level problem-solving, leading to faster resolution of defects and more reliable software.
Use cases
- Debugging a failing API endpoint in a web application by describing the error and providing a curl command as a reproduction step.
- Resolving a crash reported in a production microservice by letting the agent inspect log traces and code paths.
- Fixing a logic error in a Python script that processes data incorrectly.
- Investigating why a specific test case in a CI pipeline fails, with the agent exploring the test and underlying code.
- Assisting in root-cause analysis of a performance regression by analyzing code changes and runtime behavior.
- Rapidly patching a security vulnerability by describing the vulnerable pattern and having the agent suggest and apply a fix.
Audience
- Developers
- ML Engineers
- Data Scientists
- Researchers
Pros
- Open-source and free to use.
- Seamless integration with Visual Studio Code, leveraging its native APIs and LSP.
- LLM-powered debugging with support for user feedback during agent execution.
- Reproduction step capability enables runtime debugging and precise error localization.
- Transparent change review interface for accepting or rejecting proposed fixes.
Cons
- Manual creation of reproduction steps can be tedious and interrupts workflow.
- Currently limited to OpenAI models; broader model support is only on the roadmap.
- Prompt length management can become an issue over long debugging sessions, potentially confusing the agent.
