Summary

  • add monthly grouped updates for SHA-pinned GitHub Actions
  • add monthly uv dependency updates so pyproject.toml and uv.lock stay current
  • group development dependencies and cap each ecosystem at five open version-update PRs

Security posture

  • preserves full-commit-SHA action pinning
  • adds no workflow permissions, credentials, or privileged event handling
  • leaves already-enabled vulnerability alerts and Dependabot security updates in place

Validation

  • prek run --all-files
  • skylos --strict --danger --secrets --ai-defects .
  • verified every existing workflow action remains pinned to a full 40-character SHA

groups.dependency-type is supported only by bundler, composer, mix,
maven, npm and pip, so `dependency-type: development` matched nothing on
the uv ecosystem and every dependency would have opened its own PR.
Group by pattern instead, which is ecosystem-agnostic.

Add the pre-commit ecosystem: the six `rev:` pins in
.pre-commit-config.yaml each fetch and execute third-party code locally
and in CI, and nothing else moves them.

Set a 7-day cooldown on all three ecosystems (plus 14 days for uv major
bumps) so a freshly published release is not adopted on the day it
lands. default-days is the only cooldown key github-actions and
pre-commit support.
