Glyph Types

Deep dive into the three types of Runnable Digital Assets.

Overview

Prompts

What They Are

Prompts use large language models to generate text based on:

• A prompt template
• User-provided inputs
• Selected model tier

How They Work

User Input → Prompt Template → LLM → Output

1. User fills input form
2. Inputs are injected into template
3. Template sent to LLM
4. Response returned to user

Key Features

• Model selection - Choose AI model tier
• Template variables - Dynamic input injection
• Examples - Pre-generated output samples
• Source purchase - Buy the prompt template

Best For

• Text generation and analysis
• Creative content
• Technical documentation
• Planning and strategy

Agents

What They Are

Agents orchestrate workflows by communicating with external services via webhooks.

How They Work

User Input → Webhook → External Service → Result

1. User provides inputs
2. Agent calls webhook endpoint
3. External service processes (n8n, CrewAI, etc.)
4. Result returned to user

Key Features

• Webhook integration - Connect to any HTTP endpoint
• Async support - Long-running task polling
• Multi-step - Chain complex workflows
• Retries - Automatic failure handling

Best For

• Automation workflows
• Multi-step processes
• External service orchestration
• Scheduled tasks

Tools

What They Are

Tools wrap external APIs with payment handling and user-friendly inputs.

How They Work

User Input → Transform → API Call → Transform → Output

1. User provides inputs
2. Request is transformed
3. External API is called
4. Response is transformed
5. Result returned to user

Key Features

• API wrapping - Any HTTP API
• Authentication - Secure credential handling
• Transformation - Request/response formatting
• Rate limiting - Usage control

Best For

• Data access
• External service integration
• API aggregation
• Service proxying

Creator Requirements

Pricing

Choosing a Type

Create a Prompt When:

• Your capability is text-based
• Output comes from AI generation
• You want tiered pricing
• No external services needed

Create an Agent When:

• You need multi-step workflows
• Tasks are long-running
• External services are involved
• Complex orchestration needed

Create a Tool When:

• Wrapping an existing API
• Data access is the goal
• Simple request/response
• Authentication needed
