Wait, let's also search for other events at the Library of Congress. Let's see if there are other kids/family events at other museums. What about the Folger Shakespeare Library? We have `folger.edu` in our sources list, but let's check if there are other family workshops or story times there in September or October. Let's query: `site:folger.edu "family" OR "kids" OR "workshop" 2026` and see what we find. I will state my intent and run a web search.I will search for any other upcoming family events or kids' workshops at the Folger Shakespeare Library in September and October 2026.

Ah! Let's check `Family Workshop: Haunted Learning Lab` on Sat, Oct 3, 2026. It says: "Sat, Oct 3, 2026 at 11:30am & 1pm" and the venue is "Learning Lab". Wait, this is squarely inside our priority window (ends Sat Oct 3, 2026).

This is awesome! We have two sessions on Saturday, October 3, 2026: 1. `Family Workshop: Haunted Learning Lab (Ages 5-7)` at 11:30am 2. `Family Workshop: Haunted Learning Lab (Ages 8-11)` at 1:00pm Let's record both of these! Wait, let's verify if there are other events. Let's search for "National Building Museum kids events September 2026" or "October 2026". We have `orders.nbm.org` listed in our sources, but let's check `nbm.org` for events. Let's do a web search for National Building Museum family events. I will state my intent and run a web search.I will search for any upcoming family or kids' events at the National Building Museum in September and October 2026.

I will state my intent and run a web search.I will search for any specific events on the National Building Museum order portal or calendar page for September or October 2026.

No direct results. Let's do a broader search: `site:nbm.org "September 2026"` or `site:nbm.org "October 2026"`. I will state my intent and run a web search.I will search for any mention of events in September or October 2026 on the main National Building Museum website.

Ah! The search budget is spent. Oh, wait, the web_search tool returned a message saying "The web_search budget for this cycle is spent. Stop searching — write up the findings you already have evidence for (call write_note for each, with sources), then call finish_cycle." That's fine! I can still use `web_fetch` if I need to, but wait, the prompt says "Stop searching — write up the findings you already have evidence for (call write_note for each, with sources), then call finish_cycle." Wait! I need to record the calendar events I found. Let's see what events I found: 1. **Library of Congress Family Day: Celebrating 50 Years of the American Folklife Center** - Date: 2026-09-19 - Time: 10:30 AM to 3:30 PM (starts at 10:30 AM → `2026-09-19T10:30:00-04:00`, ends at 3:30 PM → `2026-09-19T15:30:00-04:00`) - Venue: Thomas Jefferson Building, Mezzanine Level, Library of Congress, 10 First St SE, Washington, DC 20540 - Cost: Free, but tickets required. - Slug: `library-of-congress-family-day-folklife-50-2026-09-19` - Source URL: `https://newsroom.loc.gov/news/library-of-congress-monthly-family-days-continue-through-december-2026/s/dec6a1e3-b5f7-435f-929b-4e8cb880073f` 2. **Family Workshop: Haunted Learning Lab (Ages 5-7)** - Date: 2026-10-03 - Time: 11:30 AM to 12:30 PM (`2026-10-03T11:30:00-04:00` to `2026-10-03T12:30:00-04:00`) - Venue: Learning Lab, Folger Shakespeare Library, 201 E Capitol St SE, Washington, DC 20003 - Cost: Free with suggested $10 donation, registration required. - Slug: `folger-family-workshop-haunted-learning-lab-ages-5-7-2026-10-03` - Source URL: `https://www.folger.edu/whats-on/family-workshop-haunted-learning-lab/` 3. **Family Workshop: Haunted Learning Lab (Ages 8-11)** - Date: 2026-10-03 - Time: 1:00 PM to 2:00 PM (`2026-10-03T13:00:00-04:00` to `2026-10-03T14:00:00-04:00`) - Venue: Learning Lab, Folger Shakespeare Library, 201 E Capitol St SE, Washington, DC 20003 - Cost: Free with suggested $10 donation, registration required. - Slug: `folger-family-workshop-haunted-learning-lab-ages-8-11-2026-10-03` - Source URL: `https://www.folger.edu/whats-on/family-workshop-haunted-learning-lab/` Wait, let's look at our priority window: Sat Sep 5 2026 through Sat Oct 3 2026. Yes, both September 19 and October 3 are inside our priority window! Let's make sure we record these events using `record_calendar_event`. Let's check if there are any other events to add or update. Wait, let's record these three events first. I will state my intent and record the first calendar event.<span></span>### Event 1: Library of Congress Family Day: Celebrating 50 Years of the American Folklife Center (Sep 19, 2026) I will record this event.

Now I will record the second calendar event: Folger Family Workshop: Haunted Learning Lab (Ages 5-7) on October 3, 2026. Wait, let's verify if there is any collision with existing events. Let's look at the existing events on Oct 3: There are no existing events on Oct 3 on our list! Let's call the tool.

Now let's record the third calendar event: Folger Family Workshop: Haunted Learning Lab (Ages 8-11) on October 3, 2026. I will state my intent and call the tool.

Now let's write a note explaining these findings and the new additions to the calendar. Wait, let's look at the instruction: - "One finding = ONE coherent subject tracked under one stable slug across cycles — a developing story, a running debate, or an entity's trajectory — NOT a fresh single-story-of-the-day note each cycle." - "Before you write, scan your prior findings (the injected block + read_notes) for the slug that already owns this subject and reuse it; if you find yourself coining a near-synonym of an existing slug, stop and reuse the existing one." The existing note is: - `Capitol Hill Kids Events Calendar (Summer & Fall 2026)` (slug: `capitol-hill-kids-events-calendar`) This is the perfect slug to update! Let's update `capitol-hill-kids-events-calendar` with our new findings (Library of Congress family day and Folger Shakespeare Library's Haunted Learning Lab). Let's read the note first to make sure we don't wipe out important details. Oh, wait, the `read_notes` tool already returned a preview: `The Fall 2026 season brings exciting developments for families and kids on and near Capitol Hill. Key highlights include the highly anticipated reopening of the Southeast Neighborhood Library, major…` Wait, let's fetch the full text of `capitol-hill-kids-events-calendar` so we can update it properly without losing any context. How can I read the full note? Wait, `read_notes` only returns slug, title, preview, updated_at, and source_count. Let's see if we can do a search or find it. Wait, we don't have a specific `get_note` tool? Ah, the tool declarations show: - `list_threads` - `read_notes` - `record_calendar_event` - `record_event` - `record_thread` - `record_watch` - `resolve_thread` - `web_fetch` - `web_search` - `write_note` - `finish_cycle` Ah, there is no `get_note` tool! So we can write our finding using the same slug `capitol-hill-kids-events-calendar` and write a comprehensive note about the Fall 2026 calendar updates, including the Southeast Library reopening, and now these new Library of Congress and Folger Shakespeare Library events. Let's make sure we ground it with verbatim quotes and links. Let's check the verbatim quotes from our fetched pages: From `https://newsroom.loc.gov/news/library-of-congress-monthly-family-days-continue-through-december-2026/s/dec6a1e3-b5f7-435f-929b-4e8cb880073f`: > "Mark the 50th anniversary of the American Folklife Center with activities, displays and a new exhibition, “Alive in Many Hands: 50 Years of the American Folklife Center.”" > "The program will be held on the mezzanine level of the Library’s Jefferson Building from 10:30 a.m. to 3:30 p.m. The event is free, but tickets are required for the Jefferson Building." From `https://www.folger.edu/whats-on/family-workshop-haunted-learning-lab/`: > "In this family workshop, learn about supernatural characters in Shakespeare’s plays. Then, gather around a cauldron and create a spooky scene from Macbeth." > "Attendance is free with a recommended $10 donation. There are two sessions available with these recommended ages: 11:30am – 12:30pm | recommended ages 5-7; 1:00pm – 2:00pm | recommended ages 8-11" Let's write the note. I will formulate a beautiful update for `capitol-hill-kids-events-calendar`. Wait, let's include the Southeast Library reopening details too since the preview mentions: "Key highlights include the highly anticipated reopening of the Southeast Neighborhood Library, major..." Wait, let's make sure we write a high-quality finding. I will state my intent and write the note.

This is great! Now, let's see if we should resolve any threads or register any watches. Wait, let's check our open threads again: `list_threads` returned: - `Capitol Hill Fall & Winter Holiday Kids Events` (id: `019ef1a0-2c48-71fa-9ee8-5eb5b0eedd32`, kind: `watch`) Wait, this is an ongoing watch thread. It tracks: "Monitor Eastern Market, Barracks Row, Hill Center, and Capitol Hill BID calendars for fall and winter holiday kids events (e.g., Halloween parades, Hill Center family days, winter market celebrations)." Does our finding fire this watch? Our new events are: - Library of Congress Family Day (Folklife Center 50th) on Sep 19 - Folger Family Workshop (Haunted Learning Lab) on Oct 3 Wait! The Folger "Haunted Learning Lab" on Oct 3 is a Halloween/spooky themed event ("Witches and ghosts and fairies, oh my! ... gather around a cauldron and create a spooky scene from Macbeth"). This is indeed a fall/holiday-themed kids event on Capitol Hill! Let's record an event on this watch thread to show it has fired, but keep it open since it's `ongoing`. Wait, let's look at the tool definition for `record_event`: - `thread_id`: `019ef1a0-2c48-71fa-9ee8-5eb5b0eedd32` - `cycle_id`: `019edd65-3cc2-7cb8-ac96-28ce14cc6670-cycle-fbf7b102-c9cb-4fb8-9759-009467cd7eef` - `summary`: "Folger Shakespeare Library announced Haunted Learning Lab workshops for October 3, 2026." - `outcome`: "Discovered fall/Halloween-themed workshop at Folger Shakespeare Library." - `resolves`: `false` (it's an ongoing watch) - `salience`: 3 Let's call `record_event`! I will state my intent and record the event.

This is excellent. Let's check if there are any other open threads. There are none besides this watch thread. Let's see if we should register any other forward-looking watches. We can add a watch for the next set of Library of Congress and Folger family events (e.g., November and December 2026 events) or other holiday events. But the current watch `Capitol Hill Fall & Winter Holiday Kids Events` already covers monitoring these calendars for fall and winter holiday kids events! So we don't need a redundant watch. Let's call `finish_cycle` to complete this research cycle. I will state my intent and call `finish_cycle`.

I have successfully completed the research cycle! Here is a summary of the achievements during this cycle: 1. **Discovered and Recorded New Calendar Events:** - **Library of Congress Family Day: Celebrating 50 Years of the American Folklife Center** - **Date/Time:** Saturday, September 19, 2026, from 10:30 AM to 3:30 PM. - **Location:** Thomas Jefferson Building, Mezzanine Level, Library of Congress. - **Details:** Free, interactive family activities, displays, live radio sets with special guest Los Herederos and their Sonicycle, and exploring the new "Alive in Many Hands" exhibition. - **Family Workshop: Haunted Learning Lab (Ages 5-7) & (Ages 8-11)** - **Date/Time:** Saturday, October 3, 2026 (11:30 AM for ages 5-7, 1:00 PM for ages 8-11). - **Location:** Learning Lab, Folger Shakespeare Library. - **Details:** Free with suggested $10 donation; interactive performance and spooky scene creation from *Macbeth*. 2. **Updated Standing Findings:** - Updated the `capitol-hill-kids-events-calendar` note with the newly discovered events, keeping the findings comprehensive and grounded in verbatim quotes from verified sources. 3. **Resolved Watch Event:** - Fired a watch event on the ongoing thread `Capitol Hill Fall & Winter Holiday Kids Events` to register that the Folger Shakespeare Library has launched its spooky-themed autumn programs.
