tg-set-prompt

Sets prompt templates and system prompts for TrustGraph LLM services.

Synopsis

# Set a prompt template
tg-set-prompt --id TEMPLATE_ID --prompt TEMPLATE [options]

# Set system prompt
tg-set-prompt --system SYSTEM_PROMPT

Description

The tg-set-prompt command configures prompt templates and system prompts used by TrustGraph’s LLM services. Prompt templates contain placeholders like `` that are replaced with actual values when invoked. System prompts provide global context for all LLM interactions.

Templates are stored in TrustGraph’s configuration system and can be used with tg-invoke-prompt for consistent AI interactions.

• --prompt TEMPLATE: Prompt template text with `` placeholders (required for templates)
• --response TYPE: Response format - text or json (default: text)
• --schema SCHEMA: JSON schema for structured responses (required when response is json)

System Prompt Mode

</h2>
    

<p>The <code class="language-plaintext highlighter-rouge">tg-set-mcp-tool</code> command configures and registers MCP (Model Context Protocol) tools in the TrustGraph system. MCP tools are external services that follow the Model Context Protocol specification and can be integrated with TrustGraph agents.</p>

<p>This command stores MCP tool configurations in the ‘mcp’ configuration group with:</p>
<ul>
  <li><strong>id</strong>: Unique identifier for the tool</li>
  <li><strong>remote-name</strong>: Name used by the MCP server (defaults to id if not specified)</li>
  <li><strong>url</strong>: MCP server endpoint URL</li>
</ul>

<p>Once configured, MCP tools can be referenced by agent tools using the ‘mcp-tool’ type via the <code class="language-plaintext highlighter-rouge">tg-set-tool</code> command.</p>

<p>After configuring an MCP tool, it can be used by agents through the <code class="language-plaintext highlighter-rouge">tg-set-tool</code> command:</p>

<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"># First, configure the MCP tool</span>

</h2>
    

<p>MCP tool configurations are stored in the TrustGraph configuration system under the ‘mcp’ type with the following JSON structure:</p>

<div class="language-json highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="p">{</span><span class="w">
  </span><span class="nl">"remote-name"</span><span class="p">:</span><span class="w"> </span><span class="s2">"weather-service"</span><span class="p">,</span><span class="w">

</h2>
    

<p>The MCP tool URL should point to a server that implements the Model Context Protocol specification. The server should:</p>

<ol>
  <li>Accept HTTP POST requests with MCP-compliant message format</li>
  <li>Return responses in the expected MCP format</li>
  <li>Handle authentication and authorization as needed</li>
  <li>Provide proper error handling and status codes</li>
</ol>

</h2>
    

<p>The command handles various error conditions:</p>

<ul>
  <li><strong>Invalid URL format</strong>: If the tool URL is malformed</li>
  <li><strong>API connection errors</strong>: If the TrustGraph API is unavailable</li>
  <li><strong>Authentication errors</strong>: If API access is denied</li>
  <li><strong>Configuration errors</strong>: If the tool configuration cannot be stored</li>
</ul>

<p>Common error scenarios:</p>
<div class="language-bash highlighter-rouge"><div class="highlight"><pre class="highlight"><code><span class="c"># Invalid tool URL</span>
tg-set-mcp-tool <span class="nt">--id</span> <span class="nb">test</span> <span class="nt">--tool-url</span> <span class="s2">"not-a-valid-url"</span>

</h2>
    

<ol>
  <li><strong>Use descriptive IDs</strong>: Choose clear, descriptive identifiers for MCP tools</li>
  <li><strong>Test connectivity</strong>: Verify the MCP server is accessible before configuration</li>
  <li><strong>Document tools</strong>: Keep track of MCP tool purposes and configurations</li>
  <li><strong>Monitor health</strong>: Regularly check that MCP servers are responding correctly</li>
  <li><strong>Version control</strong>: Track MCP tool configuration changes</li>

</h2>

</h2>
    

<p>The <code class="language-plaintext highlighter-rouge">tg-set-mcp-tool</code> command configures and registers MCP (Model Context Protocol) tools in the TrustGraph system. MCP tools are external services that follow the Model Context Protocol specification and can be integrated with TrustGraph agents.</p>

<p>This command stores MCP tool configurations in the ‘mcp’ configuration group with:</p>
<ul>
  <li><strong>id</strong>: Unique identifier for the tool</li>
  <li><strong>remote-name</strong>: Name used by the MCP server (defaults to id if not specified)</li>
  <li><strong>url</strong>: MCP server endpoint URL</li>
</ul>

<p>Once configured, MCP tools can be referenced by agent tools using the ‘mcp-tool’ type via the <code class="language-plaintext highlighter-rouge">tg-set-tool</code> command.</p>
<h2 id="options">

</h2>
    

<p>The MCP tool URL should point to a server that implements the Model Context Protocol specification. The server should:</p>

<ol>
  <li>Accept HTTP POST requests with MCP-compliant message format</li>
  <li>Return responses in the expected MCP format</li>
  <li>Handle authentication and authorization as needed</li>
  <li>Provide proper error handling and status codes</li>

  <li><strong>Authentication errors</strong>: If API access is denied</li>
  <li><strong>Configuration errors</strong>: If the tool configuration cannot be stored</li>

Summary:"

Variable Naming

# Use descriptive variable names
tg-set-prompt \
  --id "descriptive-vars" \
  --prompt "Analyze  data from  for  trends"

# Group related variables
tg-set-prompt \
  --id "grouped-vars" \
  --prompt "Compare  vs  using "

Environment Variables

• TRUSTGRAPH_URL: Default API URL

Related Commands

• tg-show-prompts - Display configured prompts
• tg-invoke-prompt - Use prompt templates
• tg-invoke-document-rag - Document-based AI queries

API Integration

This command uses the Config API to store prompt templates and system prompts in TrustGraph’s configuration system.

Best Practices

1. Clear Templates: Write clear, specific prompt templates
2. Variable Names: Use descriptive variable names
3. Response Types: Choose appropriate response types for your use case
4. Schema Validation: Always validate JSON schemas before setting
5. Version Control: Consider versioning important templates
6. Testing: Test templates thoroughly with various inputs
7. Documentation: Document template variables and expected usage

Troubleshooting

Template Not Working

# Check template exists
tg-show-prompts | grep "template-id"

# Verify variable names match
tg-invoke-prompt template-id var1="test" var2="test"

JSON Schema Errors

# Validate schema separately
echo '{"type": "object"}' | jq .

# Test with simple schema first
tg-set-prompt --id "test" --prompt "test" --response "json" --schema '{"type": "string"}'

System Prompt Issues

# Check current system prompt
tg-show-prompts | grep -A5 "System prompt"

# Reset if needed
tg-set-prompt --system "Default system prompt"
