# libprompt Skill ## When to Use - Managing LLM system prompts as templates - Loading prompt files from directories - Rendering prompts with dynamic variables - Organizing prompts for different agents ## Key Concepts **PromptLoader**: Loads .prompt.md files from a directory and renders them using Mustache templating syntax. **Mustache templating**: Use `{{variable}}` syntax for dynamic content insertion. ## Usage Patterns ### Pattern 1: Load and render prompt ```javascript import { PromptLoader } from "@copilot-ld/libprompt"; const loader = new PromptLoader("./prompts"); const systemPrompt = await loader.render("system", { agentName: "Assistant", capabilities: ["search", "calculate"], }); ``` ### Pattern 2: Prompt file structure ```markdown <!-- prompts/system.prompt.md --> You are {{agentName}}. Your capabilities: {{#capabilities}} - {{.}} {{/capabilities}} ``` ## Integration Used by Memory service to load agent system prompts. Prompts stored in config/agents/\*/prompts/.
