Server has 13 tools with basic schemas and descriptions, but significant gaps limit production readiness. Tool names lack consistent verb-noun structure (e.g., 'time_series_analysis' vs 'analyze_time_series'). Most descriptions are present but generic, many under 100 chars and lacking WHEN/WHY context. Parameter descriptions exist but are minimal. No output schemas documented. Error handling is absent, no recovery guidance, no categorization of retryable vs fatal errors. Security concerns: bash tool accepts arbitrary shell commands with no sanitization or permission gates. File tools (read/write/edit) lack path traversal protection. No audit logging visible. Composition issues: bash tool is too powerful and generic; should be split by use case. Analysis tools bundle multiple statistical methods into single tools rather than separate, focused tools.

• Rename tools to verb_noun pattern: 'analyze_time_series', 'analyze_bayesian', 'infer_causal', 'analyze_survival', 'query_data' (for conversational_analysis), 'generate_eda_report', 'generate_visualization'. This makes intent clear to LLMs.
• Add path validation to read/write/edit: reject paths containing '..', enforce a workspace root, and return 'Path traversal blocked: /etc/passwd is outside workspace' errors.
• Restrict bash tool: whitelist allowed commands (e.g., grep, awk, python, R), reject dangerous patterns (rm, kill, dd, curl with credentials), and require explicit confirmation for any command touching system files.
• Document output schemas for all tools. E.g., time_series_analysis returns {results: {test_name, statistic, p_value, interpretation}, diagnostics: {residuals, acf_plot}, metadata: {lags_used, model_type}}. Include field types and descriptions.
• Add error handling: wrap all external calls in try-catch, return structured errors like {error: 'file_not_found', path: '/data/missing.csv', suggestion: 'Available files: data_2024.csv, data_2023.csv'}, and categorize as retryable|user_fixable|fatal.
