Replaces astral-sh/setup-uv with jdx/mise-action in every workflow that installs uv. CI now runs the uv version in mise.lock, which is the version that local development uses. This replaces the version: latest-known approach from STF-1497.

  • install_args installs only uv, not the other tools in mise.toml.
  • The release workflow sets cache: false. zizmor's cache-poisoning audit flags mise-action when its cache is on, as it did for setup-uv.
  • The first commit updates uv in mise.lock from 0.11.29 to 0.13.7. Without it, CI would drop to uv 0.11.29.
  • Dependabot does not update mise.lock (Feature request: mise dependabot/dependabot-core#12320). To update uv, run mise upgrade uv and commit mise.lock.
  • The test jobs no longer cache uv's package cache. setup-uv cached it by default.

  • Chores
    • Updated the release and test workflows’ Python tooling setup. The test workflow also makes the installed tox command available to subsequent steps, helping automated checks run with the configured tooling.

A rabbit checks the workflow run,
As mise-action installs uv.
The release cache stays switched off,
The test path gains the tool bin.
Hop, hop—the steps are set to go.

@oschwald oschwald changed the title Use the latest known uv version in CI Install uv with mise in CI Nov 5, 2026
Replace astral-sh/setup-uv with jdx/mise-action. CI now runs the uv
version in mise.lock, which is the version that local development uses.

The release workflow disables the mise cache, as it did for the
setup-uv cache (zizmor cache-poisoning).

Dependabot does not update mise.lock. To update uv, run
`mise upgrade uv` and commit mise.lock.

- Line 26: The Windows test workflow does not add uv’s tool executable directory
to PATH, so tox may not be found. After the Install tox step, add a Windows-only
step that appends the directory reported by uv tool dir --bin to GITHUB_PATH
