• OpenAI Codex can generate code, but without the right context it often guesses—especially when working with real APIs and production workflows. This video walks through how to build a custom Codex skill for Box that gives agents the context, guardrails, and workflow patterns they need to operate reliably. Instead of relying on prompts alone, the skill defines how the agent should approach tasks like content operations, classification, and bulk file organization. You’ll see how the skill is structured, including: • A SKILL.md entry point that routes requests to the right workflows • Reference docs that keep the agent focused and context-aware • Guardrails that enforce best practices (auth, API usage, Box AI) • A bulk operations workflow for organizing large sets of files safely and deterministically The demo shows Codex using the skill to analyze and organize a Box folder of mixed documents—planning first, classifying content, and executing changes step-by-step with verification. This approach helps turn Codex from a general-purpose coding assistant into a more reliable, system-aware agent that can follow real-world development patterns.
