Inkra MCP has 18 tools with explicit schemas and descriptions, but quality is inconsistent. All tools have input schemas with proper JSON Schema structure (type, description, required fields). Naming follows verb_noun convention (document_get, document_set, folder_open). However, descriptions are terse (10-50 chars), lacking context on WHEN to use each tool or what happens on failure. Parameters lack constraints (enums, ranges, patterns). No output schemas documented. Error handling is absent, tool dispatch returns generic success messages without guidance on failure modes. Security concerns: document_open and folder_open accept absolute paths without validation, risking path traversal. No pagination support for list operations. Composition is reasonable, tools are single-purpose, but missing idempotency guarantees and chaining metadata.

• Expand all tool descriptions to 100-200 chars. Include WHAT the tool does, WHEN to use it (vs. similar tools), and what it returns. E.g., 'document_search: Finds text or regex patterns in the current document. Use this to locate specific content before editing. Returns line/column positions of matches.'
• Document output schemas for all tools. Define the structure of responses (fields, types, required). E.g., document_search should return {matches: [{line: int, column: int, text: string}], total: int}. This enables LLMs to chain calls and extract data reliably.
• Add parameter constraints: theme_set.id as enum [standard, sepia, night]; document_replace.regex as boolean with default false; folder_list_files.glob with max length 100 and pattern validation. Use JSON Schema enums and patterns, not just descriptions.
• Implement input validation and path sanitization. Reject paths outside allowed directories (e.g., /home/user/documents only). Return actionable errors: 'Path /etc/passwd is outside allowed directory. Use paths under /home/user/documents.' This prevents path traversal and guides LLM recovery.
• Add error handling with recovery guidance. Catch exceptions and return structured errors: {error: 'file_not_found', message: 'File /path/to/file not found.', suggestion: 'Check the path or use folder_list_files to browse available files.'}. Classify errors as retryable, user-fixable, or fatal.
