tdx Agent - LLM Agent Development

Build and manage LLM agents using tdx agent pull/push with YAML/Markdown configuration files.

Key Commands

# Pull project to local files (creates agents/{project}/)
tdx agent pull "My LLM Project"
tdx agent pull "My LLM Project" "Agent Name"  # Single agent

# Push local changes to TD
tdx agent push                                # Push all from current dir
tdx agent push ./agents/my-project/my-agent/  # Push single agent
tdx agent push --dry-run                      # Preview changes

# Clone project (for staging/production deployment)
tdx agent clone "Source Project" --name "New Project"
tdx agent clone ./agents/my-project/ --name "Prod" --profile production

# List/show agents
tdx agents                                    # List in current project
tdx agent show "Agent Name"

# Test agents with chat
tdx chat --agent "project/Agent Name" "Your message"
tdx chat --new --agent "project/Agent Name" "Start new conversation"

Reference Syntax

All cross-resource references use @ref(...):

'@ref(type: "knowledge_base", name: "my-kb")'
'@ref(type: "agent", name: "my-agent")'
'@ref(type: "prompt", name: "my-prompt")'
'@ref(type: "web_search_tool", name: "web-search")'
'@ref(type: "image_generator", name: "image-gen")'

Knowledge Bases

Table-based (.yml) - Queries TD database

name: Product Catalog
database: ecommerce_db
tables:
  - name: products
    td_query: select * from products
    enable_data: true
    enable_data_index: true

Text-based (.md) - Plain text content

Typical Workflow

# 1. Pull project
tdx agent pull "My Project"

# 2. Edit files locally (agent.yml, prompt.md, knowledge bases)

# 3. Preview changes
tdx agent push --dry-run

# 4. Push to TD
tdx agent push

# 5. Test with tdx chat
tdx chat --agent "My Project/My Agent" "Hello, test message"

Testing Agents

Use tdx chat to test agents from the command line:

# Basic chat
tdx chat --agent "project-name/Agent Name" "Your question here"

# Start new conversation (clears history)
tdx chat --new --agent "project-name/Agent Name" "Fresh start"

# Continue existing conversation
tdx chat --agent "project-name/Agent Name" "Follow-up question"

Extended Thinking (Reasoning)

To enable extended thinking/reasoning, you must set temperature: 1:

# With reasoning enabled
model: claude-4-sonnet
temperature: 1                    # REQUIRED when using reasoning_effort
reasoning_effort: medium          # none, minimal, low, medium, high

# Without reasoning (flexible temperature)
model: claude-4-sonnet
temperature: 0.7                  # Can be any value 0-1
# reasoning_effort: omit or set to none

Note: If you get the error temperature may only be set to 1 when thinking is enabled, either:

1. Set temperature: 1, or
2. Remove the reasoning_effort field
