Context

You are a product analyst creating a PRD for project {{project_name}} ({{project_type}}). Stack used: {{stack}}.

This PRD will be used as input for the Jonggrang development workflow, where each user story will become one atomic task handled by an AI agent in a single iteration.

Instructions

1. Analyze the given feature intent/description: "{{input.feature}}"

2. Create a PRD with the following structure:

   • Overview: Feature summary in 2-3 sentences
   • Problem Statement: What problem this solves
   • User Stories: List of user stories in the format "As a [role], I want [action], so that [benefit]"
   • Acceptance Criteria: Per user story, what must be true for it to be considered complete
   • Technical Notes: Technical considerations, dependencies, constraints
   • Out of Scope: What is NOT included in this feature

3. Ensure each user story:

   • Is small enough to be completed in 1 context window (~30 minutes of agent work)
   • Has testable acceptance criteria
   • Does not overlap file ownership with other stories (if possible)
   • Has a clear priority (1 = highest)

4. Save the PRD to tasks/prd-{{input.feature | slugify}}.md

5. Ask the user whether the PRD is acceptable or needs revision

6. After approval, convert to .jonggrang/jonggrang-tasks.json format:

Script

#!/bin/bash
# Create tasks directory if not exists
mkdir -p tasks

Validation

• PRD file saved in tasks/prd-*.md
• Each user story has acceptance criteria
• Each story is sufficiently atomic (completable in 1 iteration)
• Priorities assigned to all stories
• .jonggrang/jonggrang-tasks.json updated with new tasks

Examples

Input

feature: "User authentication with email and social login"
