When an agent connects to Delta, it sees exactly four tools, and they never change:
| Tool | Function |
|---|---|
start-here |
The briefing the agent reads once per session: how Delta works and what the rules are. |
discover-abilities |
Lists what the site can do right now, filtered by search or category. |
get-ability-info |
Returns the exact instructions for one ability before use. |
execute-ability |
Performs the work. Pages, templates, design, and media all run through this one tool. |
Everything else is an ability: one named operation, such as delta/create-page or delta/update-tokens. There are a few hundred of them, organized in categories. When the agent creates a page, it calls execute-ability with delta/create-page inside.
This design lets abilities come, go, or be switched off without breaking the connection. Install WooCommerce and about 70 store abilities appear; deactivate it and they disappear. No reconnection is needed in either case.
Enabling and disabling abilities
Every ability except the four tools can be disabled on the Abilities screen (open it from Connect). A disabled ability still appears in the agent’s list, marked as disabled, and refuses to run with a clear error. Changes apply immediately.
These controls are human-only. An agent cannot enable its own abilities, create its own tokens, or lift its own restrictions. Those controls exist only in your wp-admin.
