Unlike IDE-based tools, Chunk has access to build history, test results, and failure patterns across entire pipeline runs, enabling it to identify issues like edge cases, flaky tests, and logic errors. The agent uses your own API credentials (Anthropic or OpenAI), analyzes test history to spot intermittent failures, and generates pull requests with targeted fixes. Setup involves authorizing GitHub access and connecting API keys, with optional advanced configuration through environment setup files and custom instructions to guide bug-fixing approaches. ## Full article daily.dev links to this article rather than hosting it.
