## Install

```sh

```

Requires the [AgentStack CLI](https://agentstack.voostack.com/docs/cli). Works with Claude Code, Cursor, and any MCP-compatible agent.

## About

# 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: 
Goal: 
Folders created: Inputs, Process, Outputs, Feedback
Concept pages linked: 
Agent role: 
```

## 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.
