🚀 Introducing KeelCat — an AI-powered developer tool that automates third-party API maintenance. When an API changes, KeelCat detects the change, finds affected code across your repositories, prepares the required fix, verifies it, and opens a pull request for your team to review. No more manually tracking API deprecations, searching through code, or spending engineering hours on repetitive migrations. KeelCat is like Dependabot for third-party APIs.

Could you build this?
Partial Monitoring public API changelogs is feasible, but reliably parsing breaking AST changes across codebases, generating verified refactor patches, and automating PRs without hallucinating is difficult.
What it would actually take: Requires a pipeline of API spec diffing (OpenAPI/AsyncAPI diff engines), static code analysis / AST transformation (jscodeshift/tree-sitter), and sandboxed execution to run test suites validating the fix. The core difficulty is ensuring deterministic, accurate code refactoring across multi-repo dependencies without introducing silent regressions.
