Solid foundation with 12 well-named, read-only tools covering Cisco WLC diagnostics. All tools have descriptions (avg 180 chars, within baseline 194). Naming follows verb_noun pattern consistently (list_*, get_*). However, 11 of 12 tools have empty input schemas ({}), violating schema documentation requirements. Only get_client_detail has a proper schema with typed parameter. No output schemas documented. Error handling is minimal, tools return JSON but lack recovery guidance. No tool annotations (readOnlyHint, etc.) despite all being read-only. Descriptions are good but could be more LLM-optimized (e.g., 'When to use' and 'What it returns' sections missing).

• Add explicit input schemas to all 11 list_* and get_* tools. Even if no parameters are required, declare inputSchema: { type: 'object', properties: {}, required: [] } to signal intentional design.
• Document output schemas for all tools. Example for list_access_points: 'Returns array of {name: string, mac: string, ip: string, model: string}'. Include this in tool description or as a separate schema field.
• Add readOnlyHint: true to all 12 tools via tool annotations. This signals to agents that these calls are safe to retry and have no side effects.
• Implement pagination on list_* tools: add optional limit (default 20, max 100) and offset/cursor parameters. Cap results and document in descriptions: 'Returns up to 20 items; use offset to fetch more.'
• Enhance error descriptions with recovery guidance. Example: 'If WLC is unreachable, verify network connectivity and credentials. Retry after 30 seconds.' Use pattern:recovery-guide.
