# Repo skills as slash commands, a reasoning effort picker and GPT-6.1 Terra

Type / at the start of a task in Buildful, and the skills your repo already carries show up as commands. Search them, pick one, and the agent reads that skill's SKILL.md and follows it.

## Repo skills as slash commands

Buildful finds skills in the folders coding agents already use, like `.claude/skills`, `.agents/skills` and `.cursor/skills`, in every repo the task works on. The menu opens only when / is the first character, so a message like "/api/users is broken" stays plain text. It works in a new task and in a follow-up.

## Choose how hard a model thinks

On Pro and Team, when you pick a model yourself, a reasoning effort picker sits beside it. The levels depend on the model: Claude and GPT go from Low to Max, while Gemini 3.8 Flash offers Low and High. More effort usually means a slower task that uses more of your prepaid credit or your own key. Smart Mode and Quick Mode don't show the picker.

## GPT-6.1 Terra

GPT-6.1 Terra is in the model picker on Pro and Team. Pay for it from prepaid credit, or add your own OpenAI key. See [pricing](https://buildful.ai/pricing) for how credit works.
