Capabilities Overview

Capabilities are modular units that extend what an agent can do. Each capability can contribute:

Tools — callable functions the agent can invoke during conversations
System prompt additions — context and instructions prepended to the agent’s prompt
Features — UI elements unlocked when the capability is active (e.g., Workspace tab)

Agents compose capabilities — enable only what you need.

Quick Start

Enable via API

curl -X POST http://localhost:9300/api/v1/agents \
  -H "Content-Type: application/json" \
  -d '{
    "name": "My Agent",
    "system_prompt": "You are a helpful assistant.",
    "capabilities": ["session_file_system", "virtual_bash", "web_fetch"]
  }'

Enable via UI

Navigate to the Agent detail page
Open the Capabilities section
Toggle capabilities on/off
Reorder with drag handles (order affects system prompt priority)
Save

List available capabilities

curl http://localhost:9300/api/v1/capabilities

Key Concepts

Dependencies

Some capabilities depend on others. Dependencies are resolved automatically at runtime — you don’t need to manually add them.

Capability	Depends On
Virtual Bash	File System
Agent Skills	File System

Features

Capabilities declare UI features they contribute. The session aggregates features from all active capabilities to decide which UI tabs to render.

Feature	UI Element	Contributed By
`file_system`	Workspace tab	File System, Virtual Bash
`secrets`	Storage tab	Storage
`key_value`	Storage tab	Storage
`schedules`	Schedules tab	Schedules
`sql_database`	Database tab	SQL Database

Ordering

Capabilities are applied in the order configured on the agent. Earlier capabilities’ system prompt additions appear first. Place the most important context-setting capabilities first.
