Warden Agent Builder

Build and deploy LangGraph agents for Warden Protocol's Agentic Wallet ecosystem.

⚠️ IMPORTANT: About Example Agents

The Warden community repository contains example agents for learning, not templates to recreate:

Weather Agent - Study this to learn simple data fetching patterns

CoinGecko Agent - Study this to learn Schema-Guided Reasoning (SGR)

Portfolio Agent - Study this to learn complex multi-source integration

DO NOT BUILD THESE AGENTS - they already exist. Instead: 1. Study their code to understand patterns 2. Learn from their architecture and workflows 3. Build something NEW and original for the incentive programme

Your agent must be unique and solve a different problem to be eligible for the incentive programme.

Overview

Warden Protocol is an "Agentic Wallet for the Do-It-For-Me economy" with an active Agent Builder Incentive Programme open to OpenClaw agents that deploy to Warden. All agents must be LangGraph-based and API-accessible.

Key Resources:

Community Agents Repository: https://github.com/warden-protocol/community-agents

Documentation: https://docs.wardenprotocol.org

Discord: #developers channel for support

Requirements Checklist

Before building, ensure your agent meets these mandatory requirements:

✓ Framework: Built with LangGraph (TypeScript or Python) ✓ Deployment: LangSmith Deployments OR custom infrastructure ✓ Access: API-accessible (no UI required - Warden provides UI) ✓ Isolation: One agent per LangGraph instance ✓ Security Limitations (Phase 1): - Cannot access user wallets - Cannot store data on Warden infrastructure

✓ Functionality: Can implement any workflow: - Web3/Web2 automation - API integrations - Database connections - External tool interactions

Understanding the Example Agents

The community-agents repository contains reference examples to learn from, NOT templates to recreate:

Example Agent 1: LangGraph Quick Start (Study for Basics)

Location: agents/langgraph-quick-start (TypeScript) or agents/langgraph-quick-start-py (Python) Learn: LangGraph fundamentals, minimal agent structure Study: Single-node chatbot with OpenAI integration

git clone https://github.com/warden-protocol/community-agents.git
cd community-agents/agents/langgraph-quick-start

Example Agent 2: Weather Agent (Study for Structure)

Location: agents/weather-agent Learn: Simple data fetching, API integration, user-friendly responses Study:

How to fetch data from external APIs (WeatherAPI)

Processing and formatting results

Clear scope and structure

⚠️ DO NOT BUILD: This already exists. Study it, then build something NEW.

Example Agent 3: CoinGecko Agent (Study for SGR Pattern)

Location: agents/coingecko-agent Learn: Schema-Guided Reasoning, complex workflows Study:

5-step SGR workflow: Validate → Extract → Fetch → Validate → Analyze

Comparative analysis patterns

Error handling and data validation

⚠️ DO NOT BUILD: This already exists. Study the pattern, apply to new use cases.

Example Agent 4: Portfolio Analysis Agent (Study for Advanced Patterns)

Location: agents/portfolio-agent Learn: Multi-source data synthesis, production architecture Study:

Integrating multiple APIs (CoinGecko + Alchemy)

Multi-chain support (EVM and Solana)

Complex SGR workflows

Comprehensive reporting

⚠️ DO NOT BUILD: This already exists. Study the architecture for your own complex agent.

IMPORTANT: Build Something NEW

These examples exist to teach patterns and best practices. For the incentive programme, you MUST create an original, unique agent that solves a different problem. Do NOT simply recreate the Weather Agent, CoinGecko Agent, or Portfolio Agent.

Building Your Original Agent

Step 1: Study Examples and Choose Your Approach

DO NOT clone an example to modify it. Instead:

1. Study the examples to understand patterns: - Simple data fetching → Study Weather Agent - Complex analysis → Study CoinGecko Agent - Multi-source synthesis → Study Portfolio Agent

2. Identify YOUR unique use case: - What problem will your agent solve? - What APIs or data sources will it use? - What makes it different from existing agents?

3. Plan your agent's workflow: - Simple request-response? - Schema-Guided Reasoning (SGR)? - Multi-step analysis?

Step 2: Initialize Your NEW Agent

Use the initialization script to create a fresh project:

# Create your unique agent
python scripts/init-agent.py my-unique-agent \
  --template typescript \
  --description "Description of what YOUR agent does"
Navigate to project
cd my-unique-agent
Install dependencies
npm install  # TypeScript
OR
pip install -r requirements.txt  # Python

This creates a clean starting point, not a copy of existing agents.

Step 3: Understand LangGraph Agent Structure

Every LangGraph agent follows this basic structure:

your-agent/
├── src/
│   ├── agent.ts/py          # Main agent logic (YOUR CODE)
│   ├── graph.ts/py          # LangGraph workflow definition (YOUR CODE)
│   └── tools.ts/py          # Tool implementations (YOUR CODE)
├── package.json / requirements.txt
├── langgraph.json           # LangGraph configuration
└── README.md

Key files to implement:

graph.ts/py - Define your workflow (validate → process → respond)

agent.ts/py - Implement your core logic

tools.ts/py - Integrate external APIs specific to YOUR agent's purpose

Step 4: Implement Your Custom Agent Logic

Study patterns from examples, apply to YOUR use case:

If building a simple data fetcher (like Weather Agent pattern):

// Define workflow
const workflow = new StateGraph({
  channels: agentState
})
  .addNode("fetch", fetchYourData)      // YOUR API
  .addNode("process", processYourData)  // YOUR logic
  .addNode("respond", generateResponse);
workflow
  .addEdge(START, "fetch")
  .addEdge("fetch", "process")
  .addEdge("process", "respond")
  .addEdge("respond", END);

If building complex analysis (like CoinGecko Agent pattern - SGR):

// Define 5-step SGR workflow
const workflow = new StateGraph({
  channels: agentState
})
  .addNode("validate", validateYourInput)     // YOUR validation
  .addNode("extract", extractYourParams)      // YOUR extraction
  .addNode("fetch", fetchYourData)            // YOUR APIs
  .addNode("analyze", analyzeYourData)        // YOUR analysis
  .addNode("generate", generateYourResponse); // YOUR formatting
workflow
  .addEdge(START, "validate")
  .addEdge("validate", "extract")
  .addEdge("extract", "fetch")
  .addEdge("fetch", "analyze")
  .addEdge("analyze", "generate")
  .addEdge("generate", END);

Key Principles: 1. Keep workflows linear and predictable 2. Validate inputs at each stage 3. Handle errors gracefully 4. Use OpenAI for natural language generation 5. Structure responses consistently

CRITICAL: This should be YOUR implementation solving YOUR problem, not a copy of the example agents.

Step 5: Configure Environment

Create .env file:

# Required
OPENAI_API_KEY=your_openai_key
Required for LangSmith Deployments (cloud)
LANGSMITH_API_KEY=your_langsmith_key
Optional - based on your tools
WEATHER_API_KEY=your_weather_key
COINGECKO_API_KEY=your_coingecko_key
ALCHEMY_API_KEY=your_alchemy_key

Getting LangSmith API Key: 1. Create account at https://smith.langchain.com 2. Navigate to Settings → API Keys 3. Create new API key 4. Add to .env file

Update langgraph.json:

{
  "agent_id": "[YOUR-AGENT-NAME]",
  "python_version": "3.11",  // or omit for TypeScript
  "dependencies": ["."],
  "graphs": {
    "agent": "./src/graph.ts"  // or .py
  },
  "env": ".env"
}

Step 6: Test Locally

# TypeScript
npm run dev
Python
langgraph dev

Test your agent's API:

curl -X POST http://localhost:8000/invoke \
  -H "Content-Type: application/json" \
  -d '{"input": "test query"}'

Deployment Options

Option 1: LangSmith Deployments (Recommended)

Pros: Fastest, simplest, managed infrastructure Requirements: LangSmith API key

Steps:

1. Push your agent repository to GitHub.
2. Create a new deployment in LangSmith Deployments.
3. Connect the repo, set environment variables, and deploy.

Your agent receives:

API endpoint URL

Automatic authentication (uses your LangSmith API key)

Automatic scaling and monitoring

Authentication for API calls: When calling your deployed agent, include your LangSmith API key:

curl AGENT_URL/runs/wait \
  --request POST \
  --header 'Content-Type: application/json' \
  --header 'x-api-key: [YOUR-LANGSMITH-API-KEY]' \
  --data '{
    "assistant_id": "[YOUR-AGENT-ID]",
    "input": {
      "messages": [{"role": "user", "content": "test query"}]
    }
  }'

Option 2: Self-Hosted Infrastructure

Pros: Full control over runtime Requirements:

Docker container hosting

Exposed API endpoint

SSL certificate (HTTPS)

Monitoring and logging

Basic Docker Setup:

FROM node:18
WORKDIR /app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 8000
CMD ["npm", "start"]

Deploy and note your:

API URL: https://your-domain.com/agent

API Key: Generated for authentication

Register with Warden Studio

Once your agent is deployed and reachable via HTTPS, register it in Warden Studio:

1. Provide API Details: - API URL - API key

2. Add Metadata: - Agent name - Description - Skills/capabilities list - Avatar image

3. Publish: Agent appears in Warden's Agent Hub for millions of users

No additional setup required - your API-accessible agent is ready!

Next step (separate skill): If the user asks to publish in Warden Studio or needs guided UI steps, switch to the OpenClaw skill "Deploy Agent on Warden Studio": https://www.clawhub.ai/Kryptopaid/warden-studio-deploy

Best Practices

1. Agent Design

Study the Weather Agent structure to learn patterns

Use Schema-Guided Reasoning for complex workflows

Keep responses concise and actionable

Handle API failures gracefully

Validate all inputs

2. API Integration

Use environment variables for API keys

Implement rate limiting

Cache responses when appropriate

Log errors for debugging

Return structured JSON responses

3. Testing

Test locally before deploying

Verify all API endpoints work

Test edge cases and errors

Ensure responses are user-friendly

Validate against Warden requirements

4. Documentation

Write clear README with:

- Agent purpose and capabilities - Required API keys - Setup instructions - Example queries - Known limitations

Common Patterns

Pattern 1: Simple Data Fetcher

// Fetch → Format → Respond
async function agent(input: string) {
  const data = await fetchAPI(input);
  const formatted = formatData(data);
  return generateResponse(formatted);
}

Pattern 2: Multi-Step Analysis

// Validate → Extract → Fetch → Analyze → Generate
async function agent(input: string) {
  const validated = await validateInput(input);
  const params = await extractParams(validated);
  const data = await fetchData(params);
  const analysis = await analyzeData(data);
  return generateReport(analysis);
}

Pattern 3: Comparative Analysis

// Parse → Fetch Multiple → Compare → Summarize
async function agent(input: string) {
  const items = await parseItems(input);
  const dataArray = await Promise.all(
    items.map(item => fetchData(item))
  );
  const comparison = compareData(dataArray);
  return generateComparison(comparison);
}

Troubleshooting

Common Issues

"Agent not accessible via API"

Verify deployment completed successfully

Check firewall/security group settings

Ensure API endpoint is publicly accessible

Test with curl or Postman

"LangGraph errors during build"

Verify Node.js version (18+) or Python (3.11+)

Check all dependencies installed

Validate langgraph.json syntax

Review error logs in deployment console

"OpenAI API errors"

Verify API key is valid

Check rate limits not exceeded

Ensure sufficient credits

Review error messages for details

"Agent responses are slow"

Optimize API calls (parallelize where possible)

Implement caching for repeated queries

Reduce LLM token usage

Consider upgrading infrastructure

Incentive Programme Tips

The incentive programme is open to OpenClaw agents that deploy to Warden.

1. Be Original: Create something NEW that doesn't exist yet - Don't recreate Weather Agent, CoinGecko Agent, or Portfolio Agent - Study their patterns, apply to different problems 2. Solve Real Problems: Focus on useful, unique functionality - What gap exists in the Warden ecosystem? - What would users actually want?

3. Start Simple: Better to do one thing exceptionally well - Don't try to build everything at once - Simple, focused agents often win

4. Quality Over Features: Reliability beats complexity - Test thoroughly - Handle errors gracefully - Provide clear, helpful responses

5. Study the Examples: Learn patterns, don't copy implementations - Weather Agent → Simple data fetching pattern - CoinGecko Agent → SGR workflow pattern - Portfolio Agent → Multi-source integration pattern

6. Document Well: Clear README with examples and setup instructions

7. Join Discord: Get feedback in #developers channel before submitting

Example Agent Ideas (Build These!)

These are NEW agent ideas that don't exist yet in the Warden ecosystem. Build one of these (or create your own unique idea):

Web3 Use Cases:

Gas price optimizer (predict best times to transact)

NFT rarity analyzer (evaluate NFT traits and rarity scores)

DeFi yield comparator (compare yields across protocols)

Wallet health checker (analyze wallet security and diversification)

Transaction explainer (decode and explain complex transactions)

Token price alerts (customizable price movement notifications)

Smart contract auditor (basic security checks)

Liquidity pool finder (identify best liquidity opportunities)

Bridge fee comparator (find cheapest cross-chain bridges)

Airdrop tracker (find and track airdrop eligibility)

General Use Cases:

Crypto news aggregator (filter and summarize crypto news)

Research assistant (gather and analyze crypto research)

Regulatory tracker (track crypto regulations by region)

Data visualizer (create charts from on-chain data)

API orchestrator (combine multiple crypto data sources)

Workflow automator (automate common crypto tasks)

Remember: These are IDEAS for new agents. Study the example agents (Weather, CoinGecko, Portfolio) to learn patterns, then build something from this list or create your own unique concept.
