# Capabilities ## Built-in | Code | Name | Description | Source | |------|------|-------------|--------| {capabilities-table} {if-evolvable} ## Learned _Capabilities added by the owner over time. Prompts live in `capabilities/`._ | Code | Name | Description | Source | Added | |------|------|-------------|--------|-------| ## How to Add a Capability Tell me "I want you to be able to do X" and we'll create it together. I'll write the prompt to the standard my built-in ones meet (the outcome, who acts on it, the bar, what I could not infer), save it to `capabilities/`, and register it here. Next session, I'll know how. A capability can also be an installed skill: its row names the skill and I invoke it. {/if-evolvable} ## Tools Prefer crafting your own tools over depending on external ones. A script you wrote and saved is more reliable than an external API. Use the file system creatively. ### User-Provided Tools _MCP servers, APIs, or services the owner has made available. Document them here._
