Dev observes GPT-6 Astra skips read/write tool calls, uses bash for everything
lucasmeijer · x · 2026-09-05
Developer lucasmeijer shares a hands-on observation about GPT-6 (Astra): he has yet to see it use read or write tool calls — everything goes through bash, and "it's all you need apparently."
This suggests Astra may consolidate file I/O into shell commands within agent workflows, a notable contrast to the usual multi-tool design and a useful data point for agent tooling design.
