26 tools across 4 packages with complete JSON schemas and basic descriptions. However, descriptions are minimal (avg ~60 chars, well below 194-char baseline), many lack actionable context for LLM selection, and parameter descriptions are sparse or missing. No error handling guidance, no output schema documentation, and no tool annotations. Naming is verb-first and clear, but composition issues exist (e.g., notes_create vs notes_create_dated_topic are near-duplicates). Security concerns: path parameters (textedit_open, write_note) accept absolute paths with only weak root validation. No idempotency guarantees documented.

• Expand all tool descriptions to 100-200 chars. Include WHAT the tool does, WHEN to use it (vs similar tools), and any prerequisites. E.g., 'Create a new note with an auto-generated title (YYYY-MM-DD, <topic>). Use this for daily logs; use notes_create for custom titles.'
• Add descriptions to every parameter. For 'folder', document: 'Folder name (case-sensitive). Defaults to "Notes". Use notes_list_folders to discover available folders.' For 'name', document: 'Exact note title (case-sensitive). If multiple notes match, the first is selected.'
• Document output schemas in tool descriptions. E.g., 'Returns tab-separated lines: <title>\t<modification_date>. Dates are ISO 8601 strings.' Or return structured JSON instead of plain text.
• Implement and document path sanitization for textedit_open, write_note, move_note, textedit_save_front_to. Validate that resolved paths stay within TEXTEDIT_ALLOWED_ROOT / OBSIDIAN_VAULT_PATH. Return clear errors: 'Path traversal blocked: /etc/passwd is outside allowed root /Users/alice'.
• Add error classification to all error responses. Return structured errors: {"error": "note_not_found", "message": "Note 'Meeting' not found in folder 'Work'. Available notes: [list]. Try search_notes() to find it.", "retryable": false}. This guides LLM recovery.
