Development teams who need custom linting rules

Problem

Development teams need custom linting rules specific to their codebase that standard linters don't provide, with auto-fix and CI integration capabilities.

Requirements

Completion criteria

Teams can define custom linting rules, run them with auto-fix, and integrate into CI with detailed reports.

Optional extensions

  • Add editor integration
  • Implement rule severity levels
  • Add inline disable comments
  • Support multiple languages
