TRYIT

Each tool targets a distinct resource or action: credit/account meta (account_status, estimate_cost), discovery (trending_items, rising_creators, rising_keywords, search_content), and expansion (similar_content, find_original, analyze_channel, search_ads). The only soft overlap is between rising_keywords (today's top rising list) and keyword_trend (history for a specific keyword), where an agent might momentarily hesitate. Descriptions do enough to resolve that.

All names are snake_case and readable, mostly verb_noun (analyze_channel, estimate_cost, find_original, search_ads) with a small set of adjective_noun discovery tools (rising_creators, rising_keywords, trending_items, similar_content). The mixed pattern is minor but a strict verb_noun convention would be cleaner.

11 tools is well within the ideal 3-15 range and each tool covers a distinct capability of the trend/content research domain. No obvious filler or redundancy in the surface.

The set covers free discovery, topic search, similar-item expansion, channel analysis, ad search, origin tracing, and credit/plan introspection, which is strong lifecycle coverage. Minor gaps: no single-item get-by-id endpoint (similar_content assumes ids from search_content) and no saved search or alerting, but agents can work around these.
