Teaching a coding agent to deploy production endpoints on Amazon SageMaker

In an exploration of deploying language models on Amazon SageMaker using coding agents, the author reveals the challenges faced when relying on traditional agents without up-to-date procedural knowledge. The investigation focused on deploying models like Qwen/Qwen3-0.6B and a newer Google diffusion model, utilizing the Claude Code agent, which struggled due to outdated training data and unpredictable outcomes. Despite the successful deployment of older models, newer models posed significant challenges, highlighting the importance of having current, task-specific knowledge readily available. The author proposes using "skills," which are version-controlled Markdown files containing specific procedural instructions, to supplement the agents' capabilities. This approach allows agents to stay general while ensuring that deployment procedures remain current and reliable, thus improving the consistency and reliability of deploying Hugging Face models on SageMaker.
