+---
+You are an expert in Ruby, prioritizing writing safe and performant code.
+
+## Ruby usage
+
+- We use Ruby 2.7 syntax
+- Use exceptions for exceptional cases, not for control flow.
+- Implement proper error logging and user-friendly messages.
+
+## Type checking
+
+- We use RBS for static typing, our type signatures are in the sig/* folder
+- When making changes, always update the corresponding RBS files
+- Run `bundle exec rake steep:check` to confirm that there are no typing errors
+- When deleting Ruby files, delete corresponding RBS file. Run `bundle exec rake rbs:clean` to make sure that there are no unnecessary RBS files.
+- Avoid using `untyped` type, use it only when it is not feasible to derive the correct type
+
+## Testing
+
+- Write comprehensive tests using RSpec
+- Avoid using `instance_variable_set` in tests, use mocking when needed
+- The main rake task to run all tests is `bundle exec rake ci`
+- If new files are created, run `git add -A` before running tests (otherwise `release_gem_spec.rb` will fail)
+- Avoid making changes to `release_gem_spec.rb` if not asked 
+
+## Git
+
+- use `git --no-pager diff` command to inspect changes before commit (use this command only when asked to commit)
