Demystifying AI Agent Frameworks and Skill Invocation
TejasKumar_ · x · 2026-07-14
The author explains the interaction mechanism between AI Agent frameworks and skills, broken down into two levels: - **Harness level**: Injects the names, descriptions, and reference info of all available skills into the system prompt, guiding the Agent on when to invoke them. - **Agent level**: Employs a "lazy loading" mode. When the Agent realizes it needs a specific skill, it fetches the skill's Markdown content on-demand via tool calls, learning how to use the relevant tools in the process.
