Show HN: SunsetLint – find retiring AI model IDs in your GitHub repos

SunsetLint is a GitHub App that scans repositories for AI model identifiers with announced shutdown dates and reports each match with its file, line, shutdown date and the provider's recommended replacement. It installs with read-only contents access, posts one rolling issue per repository, and offers a Pro pull-request Check Run that flags newly added references to retiring identifiers. It does not edit code or open pull requests, does not guarantee complete coverage, and does not support GitLab or Bitbucket.
