Single tool with partial schema definition. Tool name 'publish-devto-article' follows verb_noun convention and is clear. Schema includes proper Zod validation with min/max constraints on title (5-150), content (100+), description (150), and tags (4 max, 25 chars each). However, tool description is completely missing, no text explaining what the tool does, when to use it, or what it returns. Parameter descriptions exist in schema but are minimal (e.g., 'Article title' lacks context about format or purpose). Output schema is undocumented, LLM cannot predict return structure. Error handling returns generic error text without recovery guidance. No mention of API key requirement, rate limits, or prerequisites. Follows basic naming but lacks production-grade documentation.

• Add a comprehensive tool description (50-200 chars): 'Publishes a markdown article to Dev.to. Requires DEV_TO_API_KEY environment variable. Article is immediately published and cannot be undone. Returns article ID and URL on success.'
• Document the output schema in code comments or a separate schema definition: {article_id: string, url: string, published: boolean, created_at: string}
• Enhance error messages with actionable recovery steps: 'API key missing or invalid. Set DEV_TO_API_KEY environment variable and retry.' or 'Article validation failed: title must be 5-150 chars. Got: "<actual>"'
• Add parameter descriptions for all fields in the tool definition comment, not just Zod schema. Explain what 'tags' are used for (categorization, discoverability) and format constraints.
• Implement a dry-run mode or confirmation step: add optional 'dry_run: boolean' parameter that validates without publishing, or return a confirmation prompt before executing the irreversible publish.
