missing-paths-filter

Detects heavy workflows that respond to push or pull_request without paths or paths-ignore.

Why this rule exists:

• broad triggers make docs-only and unrelated changes run the same expensive workflow

Current MVP heuristic:

• the workflow is classified as “heavy”
• no paths or paths-ignore is present for push or pull_request

Typical remediation:

• add paths for code areas that should trigger the workflow
• or add paths-ignore for files that clearly should not
