Single tool with adequate naming and schema, but significant gaps in parameter descriptions and output documentation. Tool name 'get_hn_post_formatted_comments' follows verb_noun convention and clearly conveys action. Input schema is present with type definitions. However, the post_url parameter description lacks format constraints (accepts both URL and numeric ID but doesn't specify the format clearly). Output schema is declared but lacks detailed field descriptions, 'content' and 'metadata' are vaguely documented. No error handling guidance provided to LLMs. Tool description is 194 chars (within baseline 34-392 range) but could better explain when to use this tool vs alternatives or what 'formatted' means. Missing: parameter validation rules, output field type details, error recovery guidance.

• Add explicit format constraints to post_url parameter: 'Accepts full URL (https://news.ycombinator.com/item?id=XXXXX) or numeric ID only (5-8 digits). Invalid format will return error.'
• Expand output schema with typed field descriptions: content[0].type='text', content[0].text='formatted comments string', content[1].type='text', content[1].text='summarization prompt'. Add metadata field types: postId (number), commentCount (number), postUrl (string).
• Add error recovery guidance: 'If post not found, verify the post ID is correct and the discussion is still active. If timeout occurs (>30s), retry after 60 seconds.'
• Document the 30-second timeout in tool description: 'Fetches comments with a 30-second timeout. Large discussions may timeout, consider retrying or requesting a smaller subset.'
• Clarify what 'formatted' means: 'Comments are formatted as: [path] (score: N) <replies: N> {downvotes: N} author: text. Use the included userPrompt to interpret this structure.'

Inferred effective spec: 2025-06-18+.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
