#1

Let's change our type checker to ty.

3 edit · 2 read · 2 glob

Done! I've changed the type checker from mypy to ty:

  1. pyproject.toml:26 - Updated dev dependency from mypy>=1.8.0 to ty>=0.1.0
  2. pyproject.toml:55 - Changed [tool.mypy] to [tool.ty] (configuration kept the same)
  3. .github/workflows/ci.yaml:60-61 - Updated the CI workflow step to use ty instead of mypy

The type checker configuration settings have been preserved. You may want to review the ty documentation to ensure the configuration options are compatible.

#2

Let's grep to see if there are more cases. For example, I think it's in the Claude Code configuration.

Here's a summary of all the files updated:

  1. pyproject.toml:26 - Changed dev dependency from mypy>=1.8.0 to ty>=0.1.0
  2. pyproject.toml:55 - Changed [tool.mypy] to [tool.ty]
  3. .github/workflows/ci.yaml:60-61 - Updated CI workflow to use ty
  4. .claude/hooks.yaml:11 - Updated post-edit hook to use ty
  5. .claude/instructions.md - Updated 5 references (tech stack, workflow, code style, commands, CI pipeline)
