📝 Your First ExperienceMaker Script

Here's how to get started! Note the workspace_id serves as your experience storage namespace. Experiences in different workspaces remain completely isolated and cannot access each other.

📊 Call Summarizer Examples

Transform conversation trajectories into valuable experiences using batch summarization. Each trajectory contains:

• Message: Complete conversation history between user and agent
• Score: Performance rating (0-1 scale, where 0=failure, 1=success)

The summarizer analyzes these trajectories to extract actionable insights and patterns for future interactions.

Python

import requests

response = requests.post(url="http://0.0.0.0:8001/summarizer", json={
  "workspace_id": "test_workspace",
  "traj_list": [
    {"messages": [{"role": "user", "content": "hello world"}], "score": 1.0}
  ]
})

experience_list = response.json()["experience_list"]
for experience in experience_list:
  print(experience)

curl

curl -X POST "http://0.0.0.0:8001/summarizer" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace_id": "test_workspace",
    "traj_list": [
      {
        "messages": [{"role": "user", "content": "hello world"}],
        "score": 1.0
      }
    ]
  }'

Node.js

const fetch = require('node-fetch');
// or: import fetch from 'node-fetch';

async function callSummarizer() {
  try {
    const response = await fetch('http://0.0.0.0:8001/summarizer', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        workspace_id: "test_workspace",
        traj_list: [
          {
            messages: [{ role: "user", content: "hello world" }],
            score: 1.0
          }
        ]
      })
    });

    const data = await response.json();
    const experienceList = data.experience_list;
    
    experienceList.forEach(experience => {
      console.log(experience);
    });
  } catch (error) {
    console.error('Error:', error);
  }
}

callSummarizer();

🔍 Call Retriever Examples

Intelligently search and retrieve the most relevant experiences from your workspace to enhance decision-making. The retriever:

• Finds the top-k most similar experiences based on semantic similarity to your query
• Returns pre-assembled context ready for immediate use, or raw experience data for custom processing
• Leverages your workspace's accumulated knowledge to provide contextually relevant insights

Python

import requests

response = requests.post(url="http://0.0.0.0:8001/retriever", json={
  "workspace_id": "test_workspace",
  "query": "what is the meaning of life?",
  "top_k": 1,
})

experience_merged: str = response.json()["experience_merged"]
print(f"experience_merged={experience_merged}")

curl

curl -X POST "http://0.0.0.0:8001/retriever" \
  -H "Content-Type: application/json" \
  -d '{
    "workspace_id": "test_workspace",
    "query": "what is the meaning of life?",
    "top_k": 1
  }'

Node.js

const fetch = require('node-fetch');
// or: import fetch from 'node-fetch';

async function callRetriever() {
  try {
    const response = await fetch('http://0.0.0.0:8001/retriever', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        workspace_id: "test_workspace",
        query: "what is the meaning of life?",
        top_k: 1
      })
    });

    const data = await response.json();
    const experienceMerged = data.experience_merged;
    
    console.log(`experience_merged=${experienceMerged}`);
  } catch (error) {
    console.error('Error:', error);
  }
}

callRetriever();

  -H "Content-Type: application/json" \
  -d '{
    "workspace_id": "test_workspace",
    "action": "dump",
    "path": "./"
  }'

Node.js

const fetch = require('node-fetch');
// or: import fetch from 'node-fetch';

async function dumpExperiences() {
  try {
    const response = await fetch('http://0.0.0.0:8001/vector_store', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({
        workspace_id: "test_workspace",
        action: "dump",
        path: "./"
      })
    });

    const data = await response.json();
    console.log(data);
