## Install

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

## About

# /new-rule

Scaffold a new workflow rule. Use when you (or Claude) discover a behavior worth standardizing across projects.

## Usage

```
/new-rule 
```

E.g.: `/new-rule no-emoji-in-prose`

## Pre-flight

- Verify `rules//` does not already exist (don't clobber)
- Confirm the rule isn't redundant with an existing one (check `INVENTORY.md` table)

## Steps

1. **Create directory**:

   ```bash
   mkdir -p rules/
   ```

2. **Ask the user** for:
   - One-line description (becomes `description:` frontmatter)
   - Scope: `universal | personal | ui-project | research-pkg | static-site | optional`
   - Rationale: 1-2 sentences on what bug this rule prevents / time it saves
   - Trigger condition: when does this rule kick in?

3. **Write `rules//RULE.md`**:

   ```markdown
   ---
   name: 
   description: 
   scope: 
   rationale: 
   ---

   ```

5. **Update `rules/README.md`** — add a row to the rule index table.

6. **Update `INVENTORY.md` AND `INVENTORY.zh.md`** — add a row to the Rules section table.

7. **Show the user** the diff and ask for confirmation before committing.
