libtype Skill

When to Use

• Creating typed protobuf messages
• Sharing types across services
• Working with gRPC request/response objects
• Generating resource identifiers

Key Concepts

Namespaces: Types organized by domain (common, agent, memory, graph, etc.).

fromObject(): Preferred method to create type instances from plain objects.

identifier(): Method on common types to generate resource identifiers.

Usage Patterns

Pattern 1: Create typed message

import { agent, common } from "@copilot-ld/libtype";

const request = agent.Request.fromObject({
  resourceId: common.ResourceId.fromObject({
    type: "conversation",
    id: "abc123",
  }),
  content: "Hello, assistant!",
});

Pattern 2: Generate identifier

import { common } from "@copilot-ld/libtype";

const resourceId = common.ResourceId.fromObject({ type: "message" });
const id = resourceId.identifier(); // "message:uuid"

Integration

Generated by libcodegen from proto/ files. Used by all services and librpc.
