Customization

Selesai ships a mix of bundled manifest extensions (loaded automatically), optional extensions (installed separately), and core built-in extensions (part of the runtime, not listed in the extension manifest). This page lists each one, where its settings live, and links to its guide.

Progressive capability gateway

Optional extension tools and skills are kept out of the default model context, but remain available on demand:

• Use capability_catalog to search the compact catalog.
• Use capability_discover with the exact tool name, then call the activated tool on the next turn.
• Use capability_skill_show with the exact skill name before applying a skill.

Built-in tools are unaffected. Set SELESAI_CAPABILITY_GATEWAY=0 to disable the gateway.

Every shipped, optional, and core extension is listed below with its primary configuration location and a link to its guide.
