Critical gaps across all dimensions. 17 tools with minimal descriptions (most under 50 chars), no input parameter descriptions, missing output schemas, and no error handling guidance. Tool names lack consistent verb-noun patterns (io_mkdir, fv_by_vcf, sim_by_iverilog use prepositions; assert_solver_llm, assert_inserter_llm lack clarity on what 'solver' and 'inserter' mean). Parameters like 'script', 'spec', 'fv_dir' are ambiguous without descriptions. No validation, no recovery paths, no security considerations visible. This server reads like a research prototype, not production-grade tooling.

• Add 50 - 150 character descriptions to every tool explaining WHAT it does, WHEN to use it, and what it returns. Example: 'Create a directory recursively at the specified path. Use before writing files to ensure parent directories exist. Returns success message or error if path is invalid.'
• Add descriptions to every input parameter. Example for io_mkdir: 'script: Absolute or relative directory path to create (e.g., /tmp/eda_work or ./outputs). Must be a valid filesystem path.'
• Document output schemas for all tools. Example for fv_by_vcf: 'Returns {"stderr": string, "stdout": string, "exit_code": int}. Parse stdout for assertion failures; stderr contains warnings.'
• Rename tools to verb_noun pattern: io_mkdir → create_directory, fv_by_vcf → verify_with_vcf, sim_by_iverilog → simulate_with_iverilog, uvllm → query_uvllm_results, meic → query_meic_results, rtlrepair → query_rtlrepair_results.
• Add error handling with recovery guidance. Example: 'If directory creation fails with "Permission denied", check parent directory permissions. If path contains invalid characters, use alphanumeric names and underscores only.'
