   Vercel Labs open-sources fx, a Zig coding agent built for scripting and embedding

   Vercel Labs has open-sourced fx, an experimental coding agent and CLI written in Zig that is designed to run as a scripted or embedded tool rather than as a full-screen terminal app, writing conversations into ordinary scrollback history. The same engine is exposed through a CLI and a library, with structured output for automation, Agent Client Protocol connectivity via fx acp, and libfx exposing the engine to JavaScript including a WebAssembly build. Vercel says fx ships as a 6.3 MiB native binary with single-digit MB memory and 10-microsecond cold start, but those figures are vendor-supplied rather than independently benchmarked, and early Hacker News feedback disputed its model-independent claim, with some first-time users reporting inference appeared to run through Vercel AI Gateway.

   Agent Cost-Control Engineering: Most of the Bill Isn't the Model

   A Juejin AI deep dive argues that AI agent spending is structural rather than simply price times usage, framing a fourth discipline — cost-control engineering — alongside harness, context and loop engineering. It opens with a reported Claude Code case in which a user's daily usage jumped from 161 million to 1.306 billion tokens ($41 to $493) because server errors triggered automatic retries that Anthropic customer service said count against billing without compensation. The piece then surveys caching hit rates, tool-definition bloat, Code Mode, context clearing, sub-agent isolation and budget circuit breakers, drawing on figures from Anthropic, Manus and ProjectDiscovery plus third-party harness benchmarks showing 7x to 70x cost differences. It concludes that a shorter correct path, not a cheaper model, is the real target.
