OpenAI shares prompting tips for GPT-6 Astra including a blocklist of slop words
OpenAI's documentation states that GPT-6 Astra asks clarifying questions more often than GPT-5.6 Sol, which can stop work prematurely. The company recommends prompts that instruct the model to infer user intent and show a "bias towards action." Other guidance includes auditing skill files like AGENTS.md, avoiding "slop words" such as "delve," limiting delegation to sub-agents, and rerunning tests only when failures justify it. Recommended prompts are available on the model documentation page.
