Lists multiple specific concrete actions: 'Audits files in `context/`', 'identifies discrepancies between documentation and implemented code', 'updates context files to remove outdated references, correct stale descriptions, and sync documentation with recent code changes'.

Explicitly answers both what (audits context files, identifies discrepancies, updates documentation) AND when (starts with 'Use when...' clause with specific trigger scenarios and example phrases).

Excellent coverage of natural user phrases: 'update docs', 'sync context files', 'fix outdated documentation', 'refresh context', 'context is out of date' - these are exactly what users would naturally say.

Clear niche focused specifically on context documentation in `context/` directory, with distinct triggers around 'stale', 'outdated', 'sync' documentation - unlikely to conflict with general documentation or code editing skills.

The content is lean and efficient, with no unnecessary explanations of concepts Claude already knows. Every section serves a clear purpose and the example is minimal but illustrative.

Provides concrete, specific guidance with clear decision trees (if report exists vs. not), explicit file paths, and a before/after example showing exactly what edits look like.

Clear sequential workflow with explicit checkpoints: check for context/, search for reports, handle missing reports, ask for confirmation, prompt on ambiguity. Includes verification summary as final validation step.

Well-organized with clear sections (What I do, How to run this, Example, Expected output). References external skill (`sce-drift-analyzer`) and files appropriately without deep nesting. Content is appropriately sized for a single file.
