How to Enable Tools

Method 1: Agent Configuration

Add to your agent's YAML file:

# agents/my-agent.yaml
name: My Assistant
capabilities:
  - web_search
  - calculator
  - file_read
  - file_write

Method 2: Project Configuration

Enable globally in config.yaml:

tools:
  enabled:
    - web_search
    - calculator
    - datetime

Method 3: Runtime

Enable dynamically in code:

const agent = new Agent({
  tools: ['web_search', 'calculator']
});

Tool Configuration

Setting Up API Keys

Some tools require API keys:

openclaw config set tools.web_search.api_key YOUR_KEY
openclaw config set tools.email.smtp_password YOUR_PASSWORD

Custom Tool Settings

Configure tool behavior:

tools:
  web_search:
    max_results: 5
    timeout: 10000
    safe_search: true
  
  calculator:
    precision: 10
    scientific: true

Best Practices

1. Start Small

Don't enable all tools at once. Start with 2-3 essential tools and add more as needed.

Good:

capabilities:
  - web_search
  - calculator

Too much:

capabilities:
  - web_search
  - calculator
  - file_read
  - file_write
  - email_send
  - database_query
  - http_request
  # ... 20 more tools

2. Match Tools to Use Case

Only enable tools relevant to your agent's purpose:

  • Research Agent: web_search, text_summarize
  • Calculator Agent: calculator, unit_converter
  • File Manager: file_read, file_write, csv_process

3. Configure Rate Limits

Prevent abuse and control costs:

tools:
  web_search:
    rate_limit:
      requests_per_minute: 10

4. Handle Errors Gracefully

Always expect tools to fail:

agent:
  error_handling:
    on_tool_failure: "inform_user"
    fallback_message: "I'm sorry, I couldn't complete that action."

Creating Custom Tools

If built-in tools don't meet your needs, create custom ones:

# tools/my_custom_tool.yaml
name: my_tool
description: Does something specific

parameters:
  input:
    type: string
    required: true

handler: |
  // Custom logic here
  const result = process(params.input);
  return { success: true, data: result };

Tool Combinations

Powerful workflows come from combining tools:

Example 1: Research Assistant

capabilities:
  - web_search
  - text_summarize
  - file_write

workflow:
  1. Search for information
  2. Summarize findings
  3. Save to file

Example 2: Data Pipeline

capabilities:
  - http_request
  - csv_write
  - email_send

workflow:
  1. Fetch data from API
  2. Transform to CSV
  3. Email report

Troubleshooting

Tool Not Working

  1. Check if tool is enabled
  2. Verify API keys are set
  3. Check tool-specific configuration
  4. Review error logs

Rate Limit Errors

  • Implement rate limiting
  • Add retry logic
  • Use caching
  • Upgrade plan if needed

Permission Errors

  • Check file permissions
