OpenAI publishes GPT-6 Astra guide: prune legacy prompts, Skills and AGENTS.md configs
xiaohu · x · 2026-09-14
OpenAI released official developer guidance, "Rethinking skills and prompts for GPT-6 Astra," arguing that with a new generation of far more capable models, accumulated nanny-style rules and instructions are obsolete and even harmful — developers should subtract from prompts, Skills, and config files.
Key points:
- Audit your project step by step: skills, AGENTS.md, permission boundaries, task prompts
- Full docs index at llms.txt; append .md to any doc page URL for Markdown versions
- Docs span Responses API, Agents API, Evals, fine-tuning (SFT/DPO/RFT), and reasoning best practices
