Show HN: SunsetLint – find retiring AI model IDs in your GitHub repos (www.sunsetlint.com)

A new GitHub App, SunsetLint, has been introduced to help developers identify retiring AI model IDs within their repositories. This tool scans code for specific identifiers linked to models slated for shutdown, such as Anthropic's Claude Sonnet 4.5, which is set to retire on November 30, 2026. SunsetLint not only locates the exact file and line of the code but also provides the shutdown date along with recommended replacements, ensuring developers can proactively address deprecations before they occur. The significance of SunsetLint lies in its ability to streamline the process of tracking model deprecations, a challenge for developers who often receive only general retirement notices via email without specific context. Unlike package management tools like Renovate and Dependabot, which do not account for direct model IDs in code, SunsetLint focuses on identifying these identifiers through verified rules and patterns. It offers a practical solution for teams looking to maintain compliance and functionality within their codebases, ultimately enhancing the management of AI dependencies and minimizing disruption when models retire.
