20 tools with consistent naming (verb_noun pattern: lattice_get_*) and clear descriptions (avg ~150 chars). All tools are READ_ONLY, reducing risk. Schemas present for all tools with proper required fields and parameter descriptions. However, output schemas are completely undocumented, LLMs cannot predict response structure for chaining. No error handling guidance, no pagination support despite tools returning potentially large lists (e.g., lattice_get_users, lattice_get_goals). Parameter descriptions are adequate but lack format constraints (e.g., no enum for review_type despite mentioning 'Self', 'Downward', 'Peer', 'Upward'). No tool annotations (readOnlyHint, idempotentHint) despite all being read-only. Missing batch operations and result limits.

• Document output schemas for all tools. Specify field names, types, and nested structure. Example: lattice_get_user should return {user_id: string, name: string, email: string, department_id: string, ...}. This enables LLM chaining.
• Add pagination to bulk retrieval tools: add limit (default 20, max 100) and offset/cursor parameters. Document max result count in descriptions. Example: 'Returns up to 20 users. Use offset to paginate.'
• Convert review_type parameter to an enum: {type: 'string', enum: ['Self', 'Downward', 'Peer', 'Upward']} instead of free-form string. This prevents hallucinated values.
• Add tool annotations to all read-only tools. Set readOnlyHint: true and idempotentHint: true in the tool schema. This signals to agents that these calls are safe to retry.
• Add error handling guidance to single-resource tools (lattice_get_user, lattice_get_goal, etc.). Example: 'Returns error if user_id not found. Try lattice_get_users to discover valid IDs.' This guides agent recovery.
