Argues that AI labs’ weak focus on clear, engaging writing has hurt how people perceive them.

Perception matters when builders communicate what their AI products can do, but the claim is broad.

Codex’s experimental context mode treats prompts as objects, which may help preserve context through compaction.

It points to a context-management approach worth watching for agent workflows.

Agents still reduce compaction to summarization, leaving them unable to use tools or write files during the process.

Compaction that only summarizes can strand agents without a way to inspect or persist state.
