feat: Add PRD (Product Requirements Document) Skill

[imalitavakoli]

Summary

Adds a new PRD (Product Requirements Document) skill for generating professional PRDs for requested features, following a strict template and workflow.

Tip! This skill is versioned as prd-v1 to ensure clear evolution. Future updates or major changes can be released as new versions (e.g., prd-v2), allowing users to select or reference the appropriate PRD workflow for their needs.

Features

This skill enables agents to:

• Analyse user-provided feature descriptions and map them to a PRD template
• Guide users through a structured PRD creation workflow (analyse, draft, update, validate, summarize)
• Enforce mandatory prerequisites and template section order
• Validate PRD drafts against a comprehensive checklist before finalization
• Save PRD drafts to user-specified locations and filenames

Files Included

• SKILL.md – Main skill instructions, workflow, and agent guidelines
• LICENSE.txt – Apache 2.0 license terms
• references/template.md – Official PRD template with detailed section guidance

Configuration

No special environment variables required. User must provide a clear feature description to initiate the workflow.

Example Usage

• Request a PRD for a new feature or product scope
• Follow agent prompts to supply missing information or confirm draft details
• Review and iterate on the generated PRD draft

Test plan

• Verify SKILL.md renders correctly (frontmatter, markdown, workflow steps)
• Confirm template.md matches referenced section order and content
• Test agent workflow: analyse, draft, update, validate, and summarize steps
• Ensure validation loop enforces all critical PRD sections before finalization
• Check that draft is saved to the specified directory and filename
• Confirm user is prompted if required information is missing or if file exists
