Names the domain (find-and-replace) and mentions the tool (sd) with a comparison to sed, but doesn't list specific concrete actions like 'replace patterns in files', 'rename variables', or 'batch update strings across directories'.

The 'what' is present but brief ('Modern find-and-replace using sd'). The 'when' is provided via 'Triggers on:' which functions as explicit trigger guidance, but the what portion lacks depth about specific capabilities.

Excellent coverage of natural terms users would say: 'sd', 'find replace', 'batch replace', 'sed replacement', 'string replacement', 'rename' - these are all terms users would naturally use when needing this functionality.

Clear niche focusing specifically on sd tool and find-replace operations. The explicit mention of 'sd' and comparison to 'sed' creates a distinct identity that wouldn't conflict with general text editing or other file manipulation skills.

Extremely lean and efficient. Uses tables for comparisons, minimal prose, and every section delivers actionable information without explaining concepts Claude already knows (like what regex is or how sed works).

All code examples are fully executable bash commands that can be copy-pasted directly. Includes concrete patterns for common use cases like variable renaming, import path updates, and capture groups.

The 'Safe Batch Workflow' section provides a clear 4-step sequence with explicit validation checkpoints: list affected files, preview replacements, apply, then verify with both rg and git diff.

Well-organized sections progress from basics to advanced patterns. References external file for detailed patterns with clear signaling, keeping the main skill concise while pointing to deeper content.
