Single tool with basic but incomplete definition. Tool name follows verb_noun pattern (analyze_text), which is correct. Description is present (51 chars) and explains the action adequately. Input schema has proper JSON Schema structure with type and description for the filePath parameter. However, critical gaps exist: (1) no output schema documented, LLM cannot predict returned fields; (2) error handling is minimal, errors return raw exception messages rather than actionable guidance; (3) no parameter constraints (no minLength, maxLength, or pattern for filePath); (4) missing information about what file formats are supported, expected file size limits, or line ending handling; (5) no explanation of what 'character count (excluding spaces)' means or why the tool returns three different counts instead of focusing on the most useful metrics.

• Document the output schema explicitly: 'Returns { type: object, properties: { words: { type: integer, description: "Total word count" }, characters: { type: integer, description: "Total characters including spaces" }, charactersNoSpaces: { type: integer, description: "Total characters excluding whitespace" } }, required: [words, characters, charactersNoSpaces] }'
• Add parameter constraints to filePath: minLength: 1, pattern to reject paths with invalid characters (e.g., null bytes), and description: 'Path to a UTF-8 text file (e.g., .txt, .md, .csv). Max 100MB.'
• Enhance error handling: catch fs errors specifically (ENOENT, EACCES, EISDIR) and return structured guidance. Example: 'File not found at "<path>". Check the path is correct and the file exists and is readable.' for ENOENT.
• Clarify the word-counting algorithm in the description: 'Words are defined as sequences of non-whitespace characters separated by whitespace or punctuation. Contractions like "don\'t" count as 1 word.'
• Add optional parameter 'include_summary' (boolean, default false) to return a single best-fit metric (e.g., estimated reading time based on words) rather than forcing the LLM to choose among three related metrics.
• Document supported file types and size limits in the description: 'Accepts UTF-8 text files up to 10MB. Common formats: .txt, .md, .csv, .log.'
• Return error responses with isError: true and provide a clear message that guides the LLM: 'Permission denied reading "<path>". Ensure the file is readable and the path is correct.'
