I build agent systems and the platform they run on.
Long-form notes from the inside of the work: agent architectures that survive contact with real repositories, the Kubernetes underneath them, and the unglamorous operational detail nobody writes down.
Writing
- Point, don't pasteReviewing a document with an AI still means copying a paragraph into a chat, explaining where it came from, and carrying the answer back by hand. REX puts the conversation on the document instead — every comment is a thread, the thread stays attached to its passage, and nothing reaches your file until you approve it.
- A wrong place is worse than no placeA broken anchor does not fail. It lands somewhere, reports `ok`, and paints a highlight that looks exactly like a correct one. How REX keeps a comment on its passage while the document is edited, the three times it lied anyway, and the rule that came out of it: orphan before you guess.
- A comment is a conversation that waits for youEvery REX comment is its own thread with its own agent session, stored on the document rather than in a chat window. What is stored and what is derived, how four SDKs resume a conversation four different ways, and the resume that was silently broken until a debug report asked the filesystem instead of the SDK.
