OpenAI Urges Leaner Prompts and Skill Files for GPT-6 Astra
Summary
OpenAI urges developers building for GPT-6 Astra to strip down prompts, AGENTS.md files, and skill definitions, warning that bloated context and excessive constraints can hinder the model even as it automatically runs tests and checks its work.
Key Points
- OpenAI urges developers to simplify skills, AGENTS.md files, and task prompts for GPT-6 Astra to prevent bloated context and overconstraint.
- OpenAI updates its $skill-creator guidance, recommending short, specific skill descriptions and minimal router documents that link to supporting workflows.
- GPT-6 Astra runs tests and checks work without prompting, but developers may need to explicitly tell it to continue past a first implementation until a task is complete.
