Mechanical Rules — apply automatically

name_capitalized

• Trigger: A workflow-level or job-level name: value does not start with a capital letter.
• Fix: Capitalize the first character of the name value. Do not change anything else.

permissions_exist

• Trigger: A workflow or job is missing an explicit permissions: key.
• Fix: Add permissions: {} at the workflow level if all jobs are missing it, or at the individual job level if only some jobs are missing it. Prefer job-level permissions.

pinned_job_runner

• Trigger: A job's runs-on: uses an unpinned label.
• Fix: Replace with the current pinned equivalent:
  • ubuntu-latest → ubuntu-24.04
  • windows-latest → windows-2022
  • macos-latest → macos-14

step_pinned

• Trigger: A uses: reference is not pinned to a full commit SHA (e.g., uses a tag like @v3 or branch like @main).
• Fix:
  1. Resolve the correct commit SHA via the GitHub API: gh api repos/{owner}/{repo}/commits/{ref} --jq '.sha'
  2. Show the SHA and a verification link (https://github.com/{owner}/{repo}/commit/{sha}) to the user before applying.
  3. Wait for the user to confirm the SHA. If they provide a different SHA, use that instead.
  4. Replace the uses: value with {action}@{sha} and add a comment with the original tag: # {original-ref}
  • Example: uses: actions/checkout@v4 → uses: actions/checkout@11bd71901bbe5b1630ceea73d27597364c9af683 # v4

underscore_outputs

• Trigger: A multi-word output name in a $GITHUB_OUTPUT write or outputs: block uses hyphens or camelCase instead of underscores.
• Fix: Rename the output key to use underscores. Update all references to that output within the same file.

job_environment_prefix

• Trigger: An environment variable name at the job level does not follow SCREAMING_SNAKE_CASE.
• Fix: Rename to SCREAMING_SNAKE_CASE and update all usages within the job.

check_pr_target

• Trigger: A workflow using pull_request_target has jobs not restricted to the default branch.
• Fix: Add a condition to the affected jobs: if: github.ref == 'refs/heads/<default-branch>'. Determine the repo's default branch rather than assuming main. If the job already has an if: condition, combine with && (e.g., if: <existing-condition> && github.ref == 'refs/heads/<default-branch>').

Judgment Rules — pause and ask the user

name_exists

• Trigger: A workflow or job is missing a name: key entirely.
• Fix: Ask the user what name to use, then add a name: key at the correct level with a capitalized value.

step_approved

• Trigger: A step's uses: references an action not on the Bitwarden approved actions list.
• Options to present to the user:
  1. Add to approved list — if the action is legitimate and has been reviewed and approved, add it to bitwarden/workflow-linter's approved actions config.
  2. Replace — swap with an approved alternative that provides the same functionality.
  3. Remove — delete the step if it is not essential.
• Do not make this change automatically. Show the unapproved action name, ask which option the user wants, then act.

run_actionlint (complex findings)

• Trigger: actionlint reports an error that is not a simple formatting issue (e.g., type mismatches in expressions, invalid context references, shell script errors).
• Action: Show the finding verbatim, suggest a fix based on actionlint's message, and ask the user to confirm before applying.
• Simple actionlint findings (e.g., shellcheck style warnings with a clear single-line fix) may be applied automatically.
