Names the domain (find-and-replace) and the tool (sd), and mentions batch replacement patterns, but doesn't list multiple concrete actions beyond 'find-and-replace' and 'batch replacement'. The parenthetical 'simpler than sed' is comparative context rather than a concrete action.

Clearly answers 'what' (modern find-and-replace using sd and batch replacement patterns) and 'when' (explicit 'Triggers on:' clause with specific trigger terms). The trigger guidance is explicit and actionable.

Includes a good set of natural trigger terms: 'sd', 'find replace', 'batch replace', 'sed replacement', 'string replacement', 'rename'. These cover common variations a user would naturally say when needing this skill.

The focus on the 'sd' tool and find-and-replace operations creates a clear niche. The specific trigger terms like 'sd', 'sed replacement', and 'batch replace' are distinct enough to avoid conflicts with general text editing or code refactoring skills.

The content is lean and efficient. The sd vs sed comparison table adds genuine value since it's tool-specific syntax Claude may not have memorized. No unnecessary explanations of basic concepts; every section delivers actionable information concisely.

All examples are fully executable bash commands that are copy-paste ready. The skill covers basics, common patterns (word boundaries, capture groups, import paths), and a complete batch workflow with concrete commands.

The 'Safe Batch Workflow' section provides a clearly numbered 4-step sequence with explicit validation: listing affected files first, previewing with rg -r, applying changes, then verifying with both rg (should return nothing) and git diff. This is a proper feedback loop for a destructive batch operation.

Content is well-organized into logical sections (basics, comparison, patterns, workflow, special chars, tips) and references an advanced patterns file for deeper content. For a skill of this size, the structure is appropriate with a clear one-level-deep reference.
