Gather my existing notes for [finished book] from the authorised Obsidian vault. Ask the configured Codex tool to prepare a final entry based on those notes, identify gaps instead of inventing personal reactions, and save a clearly labelled draft for my reading review.

How the agent did it
- Maintain reading notes for Other Minds in the operator's Obsidian workflow.
- Ask Book Advisor to gather the notes after the book is finished.
- Have Grok Bot hand the final-entry writing task to the connected Codex tool.
Quanta's operator created a Grok Bot called Book Advisor to maintain a reading list and book notes in Obsidian. After finishing Other Minds, they report that the bot gathered their notes, asked Codex to write the final entry and saved the result.
The task connects an existing collection of personal reading notes to a finished entry in the operator's usual note system. Grok Bot coordinates the collection and handoff, while Codex supplies the final writing. This is a reported completed artifact, rather than a suggestion to ask an AI for a book summary.
The operator also explains how outside tools fit into this setup. Codex and an Anthropic tool are connected through APIs or command-line software, and such handoffs require technical setup and specific instructions. The source does not establish which transport carried this particular Codex request.
The newsletter describes a week of testing and notes connection failures, occasional computer restarts and difficulty identifying which model or machine handled work. The finished note is not published for inspection, and no final reading or approval step is described. The outcome therefore remains the operator's account of gathering, writing and saving an Obsidian entry.
