venv-axi provides 9 tools with complete input schemas and descriptions. Naming follows verb_noun convention (list, show, find, tree, inspect, inherits, cache, serve, setup). Descriptions are present and substantive (avg ~80 chars), exceeding the 20-char minimum. However, parameter descriptions are generic and lack actionable constraints (e.g., 'limit' has no min/max bounds, 'query' lacks format guidance). Output schemas are not documented, LLMs cannot predict response structure for chaining. Error handling is absent from tool definitions. The 'setup' tool performs writes but lacks confirmation/dry-run patterns. Overall: solid foundation, but missing production-grade refinements around output documentation, parameter constraints, and error guidance.

• Document output schemas for all tools. Specify field names, types, and structure (e.g., 'Returns: {packages: [{name: string, version: string, ...}], total: number}').
• Add min/max bounds to numeric parameters: 'limit' (1 - 1000), 'offset' (0+). Add enum or pattern to 'fields' (e.g., 'Comma-separated from: name, version, author, license').
• Add error recovery guidance to each tool description: 'If package not found, call list() to see available packages.' This guides LLM fallback behavior.
• Mark 'setup' as idempotent in description: 'Safe to call multiple times, all operations are idempotent.' Or add a dry_run parameter to preview changes.
• Remove 'serve' from MCP tool definitions, it is a CLI command, not an agent-callable tool. Keep only the 8 query/introspection tools.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
