Server has 25 tools with consistent naming (verb_noun pattern: podcast_*, episode_*, recent_*, value_*, stats_*, categories_*, hub_*) and descriptions present for all. However, 3 tools (value_get_byfeedid, value_get_byfeedurl, value_get_bypodcastguid) lack visible input schemas in source, and descriptions vary widely in quality (10-200 chars). Most parameters have descriptions, but some lack type constraints (e.g., 'lang' and 'cat' filters accept free-form strings without enum constraints). Output schemas are not documented. Error handling exists but lacks recovery guidance. Composition is sound, tools chain well via IDs, but parameter validation and LLM-optimized descriptions need improvement.

• Add input schemas and descriptions to value_get_byfeedid, value_get_byfeedurl, value_get_bypodcastguid. Minimum: 'Get value/payment info for a podcast by [identifier]. Returns supported payment methods (lightning, hive, webmonetization) and recipient addresses.'
• Expand descriptions for podcast_get_* tools to 100-150 chars. Include when to use each (e.g., 'Use when you have the feed ID; faster than search. Returns title, author, description, and feed URL.').
• Convert 'lang' and 'cat' parameters to enums or add a discovery note: 'Call categories_list() first to see valid category names. Language codes: ISO 639-1 (e.g., en, es, fr).'
• Document output schemas for all tools. At minimum, list top-level fields returned (e.g., podcast_search_byterm returns [{id, title, author, description, feedUrl, ...}]). Strip API metadata (audit fields, pagination internals).
• Enhance error messages with recovery steps. E.g., 'Feed not found. Try podcast_search_byterm() to find the podcast, then use its feed ID.' Categorize errors as retryable vs user-fixable.
