The body is lean and assumes Claude's competence: no conceptual padding about what files or grep are, and every section (protocol, patterns, safety) earns its place.

Provides fully executable, copy-paste-ready commands (grep -rl/-rn, find -exec sed, PowerShell Get-ChildItem pipeline) with concrete glob and pattern examples rather than pseudocode.

A clear four-step sequence (Define, Preview, Execute, Verify) with explicit validation checkpoints — the preview gate ('NEVER batch-modify without previewing') and the verify loop ('should return empty', run tests) satisfy the feedback-loop requirement for batch/destructive operations.

A single self-contained, well-organized SKILL.md with no nested or multi-level references; no bundle files are needed for this scope, so the clean section structure alone merits the top level.

Lists several concrete actions ('bulk modifications, search-and-replace across codebases, consistent changes to many files at once') rather than vague language, matching the multi-action anchor.

The description answers 'what' clearly but contains no 'Use when...' trigger clause (the trigger guidance lives in the separate when_to_use field), capping completeness at 2 per the guidelines.

Contains relevant terms ('multiple files', 'search-and-replace', 'codebases') but omits common user phrasings like 'rename', 'update imports', or 'find and replace', so coverage is partial.

The multi-file batch niche is fairly specific but 'apply operations across multiple files' could still overlap with general editing skills, so it is not a fully distinct trigger set.
