Agent skill fromundefined-ui/second-brain-os
Set up or update a project in the vault: the four-stage folder pipeline, a project-scoped CLAUDE.md with one goal, and links to the concept pages it depends on. Use this skill when the user starts something new they will work on over time, says "create a project", "set up a folder for X", or asks to define the goal and structure of ongoing work. Do NOT use for one-off tasks, for wiki pages about a topic, or for scoping an existing project down to work in it.

Vague answers produce a file that makes every future session16 worse.172. **Create the folders:** `Inputs/`, `Process/`, `Outputs/`, `Feedback/`.183. **Write the project `CLAUDE.md`:** what this is, the one goal with a date,19 your role, working rules, current state.

That is a task.
