Server has 5 tools with complete input schemas and descriptions. Naming follows verb_noun pattern (hub_create_task, hub_refine_task, hub_task_status, hub_readiness_tree). Descriptions are present but brief (10-50 chars), below the 50-200 char LLM-optimized baseline. Parameters have types and descriptions. No output schemas documented in visible code. Error handling via ToolError exists but recovery guidance not evident. Missing tool annotations (readOnlyHint/destructiveHint). Composition is reasonable: separate read vs write tools, but hub_refine_tasks bulk operation lacks per-item error reporting.

• Expand tool descriptions to 50-200 characters. Example: 'Create a new task in the hub. Returns task_id for use in hub_refine_task or hub_task_status. Requires project_id; call list_projects first if unknown.'
• Document output schemas for all tools. Specify returned fields, types, and which IDs/references downstream tools accept. E.g., hub_create_task must return task_id so agents can immediately call hub_task_status.
• Add tool annotations: set destructiveHint=true for hub_create_task, hub_refine_task, hub_refine_tasks; set readOnlyHint=true for hub_task_status, hub_readiness_tree.
• Enhance parameter descriptions with format, range, and dependency hints. E.g., 'project_id (integer, 1-999999): Project identifier. Call list_projects to discover available IDs.'
• For hub_refine_tasks, return per-item success/failure array instead of all-or-nothing. E.g., {results: [{task_id: 1, status: 'success'}, {task_id: 2, status: 'error', reason: 'not found'}]}
