 ### Changed
 
 - Updated frontmatter description to be directive about skill triggering: now explicitly instructs invocation for IDC-related queries even without the word "IDC" in the prompt
-- Added `compatibility: allowed-tools: [Bash, Read, WebFetch, WebSearch]` to frontmatter to declare required tool scope: Bash for running code, Read for loading reference guides, WebFetch for documentation pages, WebSearch for current information
 - Extracted "Batch Processing and Filtering" (section 6) from SKILL.md to `references/use_cases.md` (Use Case 5); replaced inline code block with a 2-sentence summary and pointer
 - Extracted "Integration with Analysis Pipelines" (section 9) from SKILL.md to `references/use_cases.md` (Use Case 6); replaced inline pydicom/SimpleITK code blocks with a 2-sentence summary and pointer
 - SKILL.md reduced from 865 → 775 lines (−90 lines); `references/use_cases.md` expanded from 187 → 278 lines
