StickyInc has 6 tools with basic registration and descriptions, but significant gaps in schema completeness and parameter documentation. Tool names follow verb_noun convention (add_task, list_tasks, complete_task), which is good. However, input schemas are not visible in the provided source code, only handler imports are shown. Descriptions are present but brief (34 - 194 chars, within baseline range). No parameter-level descriptions are evident. Error handling and output schema documentation are absent. The server lacks tool annotations (readOnlyHint, destructiveHint, idempotentHint) despite having clear read/write semantics. Overall, this is a functional but under-documented implementation typical of early-stage community tools.

• Provide full schema definitions for all 6 tools in the source code. Each schema must include parameter types (string, number, boolean, array, object), descriptions (50 - 150 chars each), and constraints (enum, minLength, maxLength, pattern, minimum, maximum).
• Add tool annotations: mark add_task, add_task_natural, complete_task, schedule_event with destructiveHint=true; mark list_tasks, list_done with readOnlyHint=true. This enables LLMs to reason about retry safety and side effects.
• Document output schemas for all tools. E.g., add_task should return {task_id: string, title: string, due_date?: string, created_at: string}. list_tasks should return {tasks: Array<{task_id, title, due_date?, completed_at?}>, total: number}.
• Implement pagination for list_tasks and list_done: add limit (default 20, max 100) and offset/cursor parameters. Return total_count so agents know if more results exist.
• Add error handling guidance to add_task_natural description: 'If the LLM cannot parse the input, returns an error with the unparseable phrase and suggests rephrasing. E.g., "Could not parse: 'xyz'. Try: 'call dentist on Friday at 3pm'"'
