example code


import { createDeepAgent, type FileData } from 'deepagents';
import { MemorySaver, Command } from '@langchain/langgraph';

const checkpointer = new MemorySaver();

function createFileData(content: string): FileData {
  const now = new Date().toISOString();
  return {
    content: content.split('\n'),
    created_at: now,
    modified_at: now,
  };
}

const skillsFiles: Record<string, FileData> = {};

const skillUrl = 'https://raw.githubusercontent.com/langchain-ai/deepagentsjs/refs/heads/main/examples/skills/langgraph-docs/SKILL.md';
const response = await fetch(skillUrl);
const skillContent = await response.text();

skillsFiles['/skills/langgraph-docs/SKILL.md'] = createFileData(skillContent);

const agent = await createDeepAgent({
  checkpointer,
  // IMPORTANT: deepagents skill source paths are virtual (POSIX) paths relative to the backend root.
  skills: ['/skills/'],
});

const config = {
  configurable: {
    thread_id: `thread-${Date.now()}`,
  },
};

let result = await agent.invoke(
  {
    messages: [
      {
        role: 'user',
        content: 'what is langraph? Use the langgraph-docs skill if available.',
      },
    ],
    files: skillsFiles,
  } as any,
  config,
);

**Troubleshoot through debug in createSkillsMiddleware **



		if ("skillsMetadata" in state && state.skillsMetadata != null) {    // should be   state.skillsMetadata.length
				loadedSkills = state.skillsMetadata;
				return;
			}
