LLM Lab Book 2026-07-12: Claude fable-5 agent forks

 I'm still tracking down what makes some agents find a Nikola Tesla research finding and why others do not. Today, that's led me into investigating Claude CLI's forking harness. A few notes from me. Forking looks pretty spectacular! The agent kicks off a subagent that automatically has a copy of the parent's context. The subagent doesn't add to the parent's context until it's done. So, it seems to make things cheaper, at least for my passenger manifest research. The agent that used forking made the Tesla association. The other two agents with the same inputs and the same model did not use forking and did not find the Tesla assocation. This is important. It seems that agents that don't fork lack the persistence to look for more than one "really good" finding. They make that one good finding, and then kind of take any results for the rest of the passengs as good enough. Each forked subagent is looking for its own "really good" finding ...

Variance in Research; Manual Agent Orchestration - LLM Lab Book 2026-07-02

 More instances of variance in research results, this time around Isidore Nobel. Also, saving tokens by keeping conversations short. Missing Isidore Nobel This was probably due to a misspelling on the British manifest of Nobel's last name as Noble. The U.S. manifest has it as Nobel.  Another midweek usage reset I would say this was caused by the introduction of fable yesterday, but my usage numbers didn't reset until late last night. Yesterday, my limits were at about 21% and set to renew on Saturday. What do ticket number clusters reveal in the sorta solved Hedy Lamarr mystery? First, an update. Hedy Lamarr aka Hildegard Mandl is present on the English version of the manifest. You might remember she is not present on the United States side. No answers yet as to why. However, the English manifest has ticket numbers and people traveling together seem to have similar ticket numbers, so this is a reminder to look for something there. Why we sometimes want substrate-mediated pro...

LLM Lab Book 2026-06-30: Using LLMs with Datasette-agent and Database Prep vs Token Usage on Claude

 I'm condensing the steps to move from travel manifest page to human readable findings to sqlite database here. History Research Contextual Recap I'm working on a history of physics research project, The Gladych Files , that explores how industrialists interested in fringe physics wound up actually funding mainstream general relativity research. As part of that research, I've been looking at the travel manifests of various industrialists and research scientists from the 1930s to the 1950s. Because there are literally thousands of passengers on their combined voyages, I'm using LLM agents orchestrated through Gas Town to coordinate the research. At present, I am working on a bit of a mystery. Multiple sources state that Hedy Lamarr came to the United States aboard the S.S. Normandy, arriving on September 30th, 1937. That's the same ship that Tom Slick, (one of the industrialists of whom I spoke above), took across the Atlantic. There's only one problem. Hedy is...

Tom Slick, Hedy Lamarr the Normandy and Other Things: Lab Book for 2026-06-28/29

 I haven't mentioned my portfolio site here before, but I did manage to fix page view tracking on it today, so that's kind of nice. It was the final project for a digital portfolio  class I took at City College San Francisco and highly recommend. History Research Recap I'm offloading a significant amount of research work for my history of physics book, The Gladych Files , onto an orchestrated platform of LLM agents in Gas Town . The bulk of the work is to research passengers on trips the main characters of the book took from the 1930s to the 1950s. One of the main subjects of the book is Tom Slick . While returning from a trip to attempt to spot the Lochness Monster while he was a student at Yale—seriously, I love this book—he was aboard a ship, the Normandie, with Hedy Lamarr. The ship also had over 1,000 other passengers including the grandchildren of Henri Matisse . My  agentic AI research team comes to task because it's not a small project to research each of a t...

Controlling other Geo-Apps with CesiumJS MCP

 Moving the camera to see the sky in CesiumJS maps has always been a little bit difficult for me. So,m when CesiumJS announced their baseline MCP for controlling the camera on CesiumJS maps, I leaped at the chance to try out an MCP and to grab hold of better control of my map camera.  This week, the sujbect of eclipses came up in my Gladych Files research. ( Ferry Barrows Colton , famed National Geographic Science writer of the 1940s was part of the 1947 Brazil eclipse expedtiion, and was also on board the Normandie with Tom Slick in 1937.) That reminded me of the following picture I took of the 2017 eclipse from Wyoming.  I've wanted to identify the stars on that picture for years, so I was curious if CesiumJS had accurate constellation maps for a given date and time. Turns out, they do. But, how to look at the stars? I revived my version of the  MCP camera control server for CesiumJS in a few minutes by starting Codex in the repo directory on my local machine, a...

2026_06_25 LLM Lab Book: OCR Variance & Claude Usage Limits Reporting

 Thijs is new prior to today, usage was broken out between Sonnet and other models like this It's unclear ot me if I tripped a flag somewhere as I approached my weekly limit, or this dialog is reflective of a new Anthropic usage report. I switched Gas Town over to all Sonnet models a few weeks ago for two reasons. First, to get more usage per week. Second, I've found that for the creative research work I have the polecats (LLM agents in Gas Town parlance), Sonnet works much better than Opus 4.8. The research is for a book detailing the funding of mainstream general relativity by fringe science industrialists in the 1950s. It requires polecats to, for example, see the name Lucia Hobson, and immediately jump to the fact that Nikola Tesla was the best man at her father's wedding. Thus far, Opus 4.8 has been a little to stick-in-the-mud to pull this off, but Sonnet 4.6 makes the association for a lower token cost. Using Codex Instead I switched over to codex to run research an...

W. E. D. Stokes - Ruddering From LLMs Back Towards Ham Radio

 While doing research for a book I'm working on, The Gladych Files , I wondered into the weeds of statistical analysis of LLM AI agent performance which relates to my everyday sort of work in engineering. One of the things I really enjoy about The Gladych Files, however, is that it's never long before the project pulls me back towards ham radio. The statistical analysis project involved determining how often, and with what certainty AI agents could find out that Lucia Hobson was the daughter of Rear Admiral Richmond Pearson Hobson and then make the further link that Nikola Tesla was the best man at Rear Admiral Hobson's wedding. While estimating how difficult this was to do with plain old human operated web searches this morning, I came across W. E. D. Stokes! Stokes came into the picture as Lucia Hobson's husband. What I didn't know was that he was one of the founders of The Radio Club of America. His original interest in radio came from wanting to control a mod...
