# Feature Spec

Feature Spec creates a complete product feature specification with acceptance criteria, scope, dependencies, and risks by delegating to the Prometeo (PM) agent. Use it to define new features, write user stories with acceptance criteria, and document business requirements before implementation.

**Install:**

```bash
npx degit https://github.com/davepoon/buildwithclaude/tree/main/plugins/agent-triforce/skills/feature-spec ~/.claude/skills/feature-spec
```

## README

# Feature Spec

Creates a complete product feature specification using the Prometeo (PM) agent.

## When to Use This Skill

- Defining a new feature or product requirement
- Writing user stories with acceptance criteria
- Planning product work that needs a structured spec
- Documenting business requirements before implementation

## What This Skill Does

1. Runs the SIGN IN checklist (identity, task, memory review)
2. Researches existing specs to avoid conflicts
3. Creates a comprehensive spec at `docs/specs/{feature-name}.md`
4. Runs the Spec Completion checklist (TIME OUT)
5. Prepares a structured handoff to the Dev agent
6. Runs the SIGN OUT checklist (memory update, deliverables)

## How to Use

### Basic Usage

```
/feature-spec user authentication with JWT tokens
```

### Detailed Usage

```
/feature-spec multi-tenant billing system with Stripe integration
```

## Example

**User**: `/feature-spec webhook event system`

**Output**: A complete spec at `docs/specs/webhook-event-system.md` containing:
- Problem statement and success metrics
- User stories with GIVEN/WHEN/THEN acceptance criteria
- In-scope and out-of-scope items
- Dependencies, risks, and open questions
- Handoff notes for the Dev agent

## Tips

- Be specific about the feature scope in your description
- The agent will ask clarifying questions rather than guess
- Review the generated spec before passing to implementation
