Second Brain Project Skill for Claude

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

• 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.

• Create the folders: Inputs/, Process/, Outputs/, Feedback/.
• 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.

• 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.

• 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>

Calibration

Feedback/ is the folder people skip and the one that makes the system improve.

If the user has no idea what would go in it, that is worth surfacing: it usually

means the goal is not measurable yet.

Do not create a project for work that finishes this week. That is a task.
