AI detectors flag non-native English as machine-written. callus scores your draft against your own voice instead. pip install callus.

Debates over disruptive tools follow a pattern. The vibe coding fight is at a recognisable stage of it. Notes from someone who passed through an earlier version of the same argument.

fscars 0.1.0 is out — a bolt-on correction primitive for AI coding agents, built on the framework from the Lucy Syndrome paper. Apache 2.0, pip install fscars.

Anthropic shipped managed memory stores in April. They sit at the third of four layers. The fourth, hooks, is the one that closes the Lucy loop.

LLMs don't remember yesterday. That gap has a name, a causal mechanism, and a fix that doesn't require better memory.

LLMs don't remember yesterday — and that gap has a name. A five-part essay on the Lucy Syndrome, functional scars, and what it takes for a production system to actually learn.

Questions about the Lucy Syndrome essay — its scope, its method, and what functional scars actually look like in operation. Compiled from real conversations and updated as new questions arrive.

The informal companion to the Lucy Syndrome essay — how the observation started, how the system around it took shape, and why an operator in Paraguay ended up writing about model amnesia.
