Single tool 'create_vote' has a well-structured JSON Schema with proper type definitions, constraints (minItems: 2, maxItems: 9), and parameter descriptions. The tool description is clear and contextual (145 chars), explaining WHAT it does, WHEN to use it, and the expected workflow. However, the tool lacks output schema documentation, callers cannot see what fields the response contains or how to chain downstream operations. No error handling guidance is provided (e.g., what happens if vote creation fails, or if the Chzzk connection drops mid-vote). The tool name 'create_vote' follows verb_noun convention correctly. Overall, this is a solid single-tool implementation but incomplete for production use.

• Add explicit output schema to create_vote: document fields like vote_id (string), status (enum: 'active'|'closed'), question (string), options (array), created_at (ISO 8601), expires_at (ISO 8601). This enables downstream tool chaining and LLM planning.
• Add error handling guidance: 'If Chzzk connection fails, the vote will not be created. Retry after reconnecting via the dashboard. If the question exceeds 200 chars, shorten it and retry.'
• Implement a dry-run parameter (optional boolean, default false) or add a confirm_vote tool to gate vote creation. This prevents accidental duplicate votes.
• Constrain the 'options' parameter: add maxLength (e.g., 50 chars per option) and document that options must be distinct and non-empty. Add a pattern constraint if needed.
• Provide bilingual descriptions (Korean + English) for accessibility to non-Korean developers maintaining or extending this server.
