Field notes
What should readers understand next?
A Codex Skill Turns Multi-Agent Work Into a Reusable Control Surface
A shared Codex orchestration skill points to a future where agent workflows are packaged as portable operational routines.
Brute Intelligence Industrializes Trying Stuff
Benn Stancil argues that AI changes work by making trial, cleanup, and iteration cheap enough to become an operating model.
Claude.md Shrinkage Says the Harness Is Learning What Not to Say
A reported 80 percent reduction in Claude Code prompt material points to a maturing harness discipline around concise system context.
Codex Hooks Close the Type Error Loop
Codex hooks make validation output an active part of the agent loop, so type errors and checks can be returned before the task drifts.
OpenRouter Classifiers Route Inference by Work Type
OpenRouter classifiers point to a gateway layer that labels tasks, routes inference, and turns model choice into operations policy.
Prompt Caching Turns Agent Context Into Infrastructure
Earendil frames prompt caching as an agent systems primitive, where stable context becomes a cost, latency, and architecture concern.
Anthropic Cuts Limits and Rents Compute from Meta
Compute is becoming part of the AI product contract: Claude limits, plans, and availability depend not only on prompts but on where the lab can find capacity.
