39 tools with mostly adequate naming and descriptions, but significant gaps in schema completeness and error handling. Tool names follow verb_noun convention well (files_list, note_create, semantic_search). Descriptions average ~80 chars, below the 194-char baseline for A+ tools. Input schemas present but sparse: most parameters lack type constraints, enums, and validation guidance. No documented output schemas. Error handling is minimal, tools do not guide recovery or categorize failures. Semantic search tools (5) are optional dependencies, adding complexity. Destructive operations (note_trash, clear_index) lack confirmation patterns.

• Document output schemas for all 39 tools. Include field names, types, and whether results are paginated. Example: 'Returns {files: [{path: string, size: number, modified: ISO8601}], total: number}'.
• Add confirmation/dry-run pattern to destructive tools. Implement a 'confirm' parameter or separate 'preview_trash' tool that shows what would be deleted before execution.
• Add enum constraints and format descriptions to all string parameters. Replace 'path: string' with 'path: string (file path, max 255 chars, no leading /)' and use enums for status/type fields.
• Implement error categorization and recovery hints. Return structured errors: {code: 'NOT_FOUND', message: 'Note not found', retryable: false, suggestion: 'Try search() first'}.
• Restrict eval tool to sandboxed contexts or require explicit user confirmation. Document security implications and audit requirements. Consider removing or gating behind admin-only permissions.
