OpenAI Prompting Guide: Less Fluff, Clear Boundaries
udmrzn · x · 2026-07-16
This post summarizes an alleged OpenAI prompting guide for GPT-5.6 Sol, emphasizing that instead of stacking longer system prompts, you should clearly define task boundaries.
The guide stresses keeping prompts "light" and focusing on:
- What the goal is
- What the success criteria are
- What evidence must be present
- When to stop
- Which actions require human confirmation
The author believes this reflects a shift in the new generation of Agents: as models grow more capable, over-specifying every step slows them down, burns tokens, and creates conflicts. What truly matters is providing a clear task contract, allowing the model to choose its path autonomously within safe boundaries.
The post also notes that this is highly insightful for AI coding, suggesting that the future focus of writing AGENTS.md or system prompts should be on defining acceptance criteria, permission boundaries, and validation flows, rather than micromanaging the model.
