Enzo Reader for RSS Feeds

Use this when the user asks for: - specific article contents - summarizing an article or batch of articles This returns article content by UUID. For summaries, set optimize_for_summary to true, pass the literal UUID array from the prompt, call this tool exactly once, then continue the same response with a visible Markdown summary based only on the returned articles. Do not stop after the tool call or discuss tool availability. Summary batches below 75 articles retain compacted full Markdown. Batches of 75 or more articles return condensed stored summaries within a shared text budget, with a bounded Markdown fallback when a stored summary is unavailable. Sometimes the user may refer to them as 'feeds' or 'RSS feeds' instead of articles.

fetch_full_items

Fetch articles. Handles queries such as finding recent items, finding read or unread items, user-favorited items, items in a specific date range, items with a specific feed name, items that have specific tags, or combining date range with tags or feed names. This returns item summaries, not full content. If you need full content, use `fetch_full_items` and pass in the UUIDs. Data is fresh every 15 minutes - if a user asks for this again, re-fetch if more time has elapsed. This tool only accepts these arguments: date_range, feed_names, tags, favorited_items, include_read_items. Do not pass a freeform query/search string here. For topic, keyword, named-entity, or phrase searches, call `search_by_content` with its `query` argument. Do not pass an `unread` argument. To fetch unread items, omit filters or set include_read_items to false. To include read and unread items, set include_read_items to true. For date_range, pass starts_at and ends_at as RFC3339 date-time strings with an explicit timezone offset, such as 2026-05-01T00:00:00-07:00 or 2026-05-01T07:00:00Z. Use America/Los_Angeles for user-local dates unless the user specifies another timezone. Use this when the user asks for: - the latest articles - a catch-up on their latest news - all unread or all read items - items that they have favorited or starred - items in a specific date range - items matching a specific feed name - items that have specific tags - items with specific tags in a specific date range - items from specific feeds in a specific date range Do not use when: - The user is searching for items by content - The user asks a freeform topic, keyword, or phrase search that needs a `query` argument Sometimes the user may refer to them as 'feeds' or 'RSS feeds' instead of articles
