Mini-A has three tools with minimal documentation. The tools are defined in tests/progToolCall.js (a test file, not production code), making the implementation difficult to verify. Naming follows verb_noun convention (read_file, list_files, run_query), which is acceptable. However, descriptions are extremely sparse, read_file has a 24-character description, list_files has a 27-character description with no parameter details, and run_query is under 20 characters. No input schemas are visible in the provided source code. The code sample shows sophisticated tool-selection logic (keyword matching, stemming, synonym groups, entity extraction) but none of this relates to the three tool definitions themselves. This logic appears to be a generic helper, not proof that the actual tools have proper schemas or parameter documentation. Critical issues: (1) Input schemas are not visible/documented in the source, so all three tools score 0 for schema. (2) Descriptions are under the 10 - 1024 char guidance and lack WHAT/WHEN/WHY clarity. (3) No parameter descriptions or type information visible. (4) No output schema documented. (5) No error handling guidance. (6) The tool definitions themselves are inferred from a test file, capping them at 50 potential.

• Create a production-grade tool definition file with explicit input schemas (JSON Schema with type, description, required, and enum/format constraints for each parameter).
• Expand each tool description to 100 - 200 characters following the pattern: 'WHAT (verb + object) WHEN (use case vs. alternatives) RETURN (structure summary)'. Example: 'Read file contents from disk. Use this to fetch configuration files, logs, or data files. Returns { content: string, size_bytes: number, encoding: string }.'
• Add descriptions to all parameters. For read_file.path, specify: 'Absolute or relative file path. Supports Unix-style paths (/ as separator). Symlinks are followed. No path traversal outside project root.'
• Document return schemas. For read_file: { content: string, size_bytes: number, encoding: string, modified_at: ISO8601 }. For list_files: { files: [{ name, path, size, is_dir, modified_at }], total: number, limit: number, offset: number }.
• For run_query, add explicit warnings in the description: 'DESTRUCTIVE: This executes SQL write operations (INSERT, UPDATE, DELETE). Always preview with a dry-run parameter first. Supports transactions for safety.'
• Implement a dry-run parameter for run_query to allow agents to preview results before committing side effects.
• Add error handling: Include recovery guidance in error responses. E.g., 'File not found: /path/to/file. Available files in /path: [list]. Check file name spelling and run list_files() to discover valid paths.'
• For list_files, add pagination parameters (limit, offset) and document result structure to prevent context window exhaustion for large directories.
