Agent Frameworks Considered Harmful — Rémi Louf, .txt

In the first week the daily brief posted to Slack twice, a voice note vanished entirely, and the market brief turned to garbage after prompt edits Rémi Louf had not versioned and could no longer recall. Each failure became a piece of what turned into a runtime. The lost note became an append only log where nothing is discarded and every event is causally linked to the one that triggered it. The duplicates became a real queue that counts attempts. The untraceable prompt became a content addressed store, and that one was the rabbit hole. Every part of a prompt is hashed and stored separately, the system message, each skill description, each tool definition, the user question, so a prompt is a list of hashes rather than a rendered string. Diff two runs and you see exactly which component changed. Replay one against a different model and the request rebuilds from the graph. He wanted this because a live chat session does not show you what the model actually saw, not with compaction and unshared reasoning in play. The rest stays deliberately small. Agents are markdown files you drop in a folder, so people who do not write code can add one. They subscribe to events instead of living in a graph with edges to maintain. Typed tool calls and typed events are the two boundaries, because roughly 20% of his events were coming back malformed and getting rejected. He took two weeks away from running a 15 person company to build it. Twenty agents now run there.
