Search Action Items

SearchActionItems
Full Description

Find action items that match a given search term or filter. Returns action items with their title, description, status, assignee, and related meeting details. Action items can have zero, one, or multiple related meetings. The meetings array contains all related meetings you can access and is empty when there are none. The nullable meeting field is retained as a representative meeting for compatibility. By default, only action items assigned to the user are returned. To find action items assigned to someone else, use FindProfiles to resolve their name to a profile ID and pass it as assigneeProfileId. Action items can be filtered by search terms, status (PENDING or DONE), tags, and meeting date range (startDate/endDate). Returns up to 25 action items per page. Request the next pageIndex only when the page contains 25 action items and more results are needed. For exhaustive requests, continue until a page contains fewer; otherwise stop when the user's request is satisfied.

Parameters (2 required, 6 optional)
Required
intentstring

The reason why this tool call is being done. This intent is likely to be either the user's original question or the reason to investigate further based on their question.

pageIndexnumber

The page index to fetch. Always start with page 0.

Optional
assigneeProfileIdnumber

Optional profile ID to filter action items by assignee. Use FindProfiles to resolve a name to a profile ID. Always set this when the user mentions a specific person, including themselves. When omitted, only action items assigned to the user are returned.

endDatestring

Optional ISO date string (yyyy-MM-dd) for latest date to include results from.

searchTermsarray

statusstring

Search Calendar Events

SearchCalendarEvents
Full Description

Returns upcoming calendar events from the authenticated user's connected calendars, with pagination and a configurable time window. Get calendar events from the user's connected calendars. When searching for calendar events, the tool will extract relevant excerpts based on the intent instead of returning the entire data. Each calendar event excerpt includes comprehensive details: event title, date (in the user's timezone), organizer email, attendees (with names, emails, and status), calendar description (if present), meeting platform (Zoom, Google Meet, Microsoft Teams, etc.), meeting platform link, whether it's a recurring event, Circleback join status, and any associated meeting data from the Circleback (meeting ID, status, tag IDs, user notes). You can filter events by providing a date range using startDate and endDate parameters. This is useful for finding upcoming meetings, scheduled calls, or calendar events that the user has. Note: This should be primarily used for searching calendar events happening in the future. Past calendar events have a meeting record if they were captured with Circleback. The only reason to use this to search past calendar events is if searching for the meeting with SearchMeetings yielded no relevant results. Returns up to 50 calendar events per page. Request the next pageIndex only when the page contains 50 events and more results are needed. For exhaustive requests, continue until a page contains fewer; otherwise stop when the user's request is satisfied.

Search Emails

SearchEmails
Full Description

Search the user's connected email accounts for email threads matching a query. This should be used when the user asks questions about their emails or needs to find specific email conversations. This function queries across all connected email services and retrieves up to 20 matching email threads per service per page. The data returned will be an array of objects, with each containing the email thread ID, subject line, and relevant excerpts. Each email thread object includes metadata such as the sender email, received date, and the fromEmailAddress of the connected account the thread belongs to (if available). Only 20 email threads are returned per page, so this function may need to be called multiple times if there are more than that many results.

The page index to fetch. Always start with page 0.

Search Meetings

SearchMeetings
Full Description

Find meetings that match a given search term or filter.

Searches match every keyword, in any order, within the meeting name or within its notes. Matching ignores case and treats punctuation between query words as separators. Partial words are supported; misspellings are not corrected. Prefer a few distinctive keywords; omit searchTerm for filter-only searches. Include date, tag, attendee, or domain filters when they are supplied by the user or established in the conversation. Do not invent a date range to narrow the search. Returns an array of meeting summaries with relevant source excerpts based on intent. Use ReadMeetings for details about selected results. Returns up to 20 meetings per page. Request the next pageIndex only when the page contains 20 meetings and more results are needed. For exhaustive requests, continue until a page contains fewer; otherwise stop when the user's request is satisfied. Keep all other search parameters identical when changing pageIndex.
