Summary

• Pin CI and pre-commit to actionlint 1.7.12 for consistent workflow validation.
• Add the pinned actionlint pre-commit hook and a wrapper that skips ShellCheck on Darwin to avoid actionlint's pipe deadlock; Linux CI retains ShellCheck.
• Preserve the existing actionlint commit without including the separate guardrail changes.

Dependencies

This PR contains one commit directly above upstream/main and changes only the CI workflow, pre-commit configuration, and actionlint wrapper. It is independent of the guardrail PR and can merge in either order.

Validation

• Pre-commit checks passed for all three changed files before pushing.
• The complete commit diff and branch tracking were inspected.
• git diff --check passed.

• CI: Pins the actionlint version to 1.7.12.
• Code quality: Adds a pre-commit actionlint hook pinned to v1.7.12. On Darwin, the wrapper disables ShellCheck to avoid an actionlint pipe deadlock; on other platforms, it passes arguments to actionlint unchanged.
• Tests: Results are not available.

Walkthrough

The CI workflow pins actionlint to version 1.7.12. The pre-commit configuration adds an actionlint hook that uses a Bash wrapper. The wrapper disables ShellCheck on Darwin and passes supplied arguments unchanged on other platforms.

A narrow Darwin pre-commit workflow can hang on large Python run blocks; disabling Pyflakes is advisable before merging.

Full details: Title check

Explanation

The title "ci: pin actionlint version and add pre-commit hook" matches the main changes. The CI workflow pins actionlint to 1.7.12, the pre-commit config adds an actionlint hook at v1.7.12, and a wrapper script is added. The title does not mention the Darwin ShellCheck skip, but it covers the primary change and is specific enough for a reviewer scanning history.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 0 functions across 1 files.

Minor · Stability & Availability · Quick win

Disable Pyflakes on Darwin too.

If Pyflakes is installed and a Python run: block exceeds the pipe capacity, actionlint v1.7.12 can still hang the commit. Pyflakes uses the same pipe code as ShellCheck. (raw.githubusercontent.com)

Add -pyflakes= on Darwin, or use an actionlint build with the upstream pipe fix. (github.com)
