second-brain-project skillA

second-brain-project is agent-read markdown (skill) from undefined-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..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

What the file says

# Set up a project

The knowledge layer answers what you know. The project layer answers what you
are doing this week. Merging them fills a wiki with dead task lists and buries
working files under conceptual notes.

## Core rule

One goal per project, stated in its own `CLAUDE.md`. A project with three goals
is three projects.

## Workflow

1. **Interview if needed.** What this produces, for whom, by when, and what the
   agent's role is. Vague answers produce a file that makes every future session
   worse.
2. **Create the folders:** `Inputs/`, `Process/`, `Outputs/`, `Feedback/`.
3. **Write the project `CLAUDE.md`:** what this is, the one goal with a date,
   your role, working rules, current state. Name what the agent should not do
   here as well.
4. **Link the knowledge layer.** Find concept pages the project depends on and
   reference them from the project file. Copy into `Inputs/` only the few that
   genuinely matter.
5. **Register it** in the root `CLAUDE.md` project list.

## Output format

```
Project: <name>
Goal: <one measurable outcome with a date>
Folders created: Inputs, Process, Outputs, Feedback
Concept pages linked: <list>
Agent role: <one line>
```
