Three tools with minimal structure. All have descriptions (10-50 chars baseline), but lack critical schema detail. Input schemas present but parameters lack type constraints and validation guidance. No output schemas documented. No error handling guidance. Tool names are generic action verbs ('get', 'set', 'run') that do not clearly distinguish responsibilities, LLMs will struggle to pick the right tool. Parameters accept free-form strings with no enums, ranges, or format constraints, inviting hallucinated commands. No security controls visible (credentials in env vars is good, but no rate limiting, input sanitization, or permission gates). Composition is poor: three tools do overlapping things (all send commands), violating single-responsibility principle.

• Rename tools to verb_noun format: 'query_opensim', 'execute_opensim_command', 'manage_opensim_region'. Names should convey action and domain, not generic verbs.
• Add enum constraints to 'command' parameter: list valid command categories (show, set, change, region, terrain, save, etc.) or accept a structured command object with subcommand + args.
• Document output schema: specify that responses are plain text, include max length, and provide examples of success vs error responses. Consider parsing responses into structured JSON (status, output, errors).
• Add error handling guidance: 'If command fails, check syntax against OpenSimulator console docs. Common errors: invalid region name, permission denied, command not found. Retry with corrected syntax or call query_opensim to list valid options.'
• Consolidate 'get' and 'set' into a single 'execute_opensim_command' tool with a 'mode' enum (read_only, mutating, any). Remove 'run' to eliminate duplication. This reduces cognitive load on LLM tool selection.
