Extend Colossus¶
Choose what you want to build. Each guide starts with a concrete workflow, connection, or file you can make your own.
Automate work¶
-
First workflow
Create, validate, register, and run a workflow with no external effects.
-
Workflow authoring
Define inputs, steps, capabilities, and execution bounds.
-
Triggers and recovery
Start workflows from schedules or events and handle interrupted runs.
Add tools and editors¶
-
Tools
See the active tool catalog and what each field means.
-
Agent Plugins
Package and distribute Agent Skills, resources, and MCP servers.
-
Integrations
Connect a supported service or import OpenAPI operations.
-
MCP
Configure an external tool server for Colossus to use.
-
ACP in editors
Use Colossus as a local agent in a compatible editor.
Customize the terminal¶
-
Author a theme
Create a TOML theme, preview it, and select it in the terminal UI.
Configured extensions still use Colossus's access, approval, sandbox, and audit boundaries.
