OpenSpec

Spec-driven development plugin for breaking down PRDs into actionable specifications and tasks. Complements the existing OpenSpec commands (/openspec:proposal, /openspec:apply, /openspec:archive) with PRD analysis and breakdown capabilities.

Commands:

• /openspec:prd-breakdown - Break down PRD into specs and tasks with full implementation plan
• /openspec:prd-split - Split large PRDs into smaller, manageable feature specifications
• /openspec:prd-analyze - Analyze PRD complexity and suggest breakdown strategies
• /openspec:spec-review - Review and validate specs for completeness and quality

Features:

• Intelligent PRD analysis and complexity assessment
• Automatic breakdown of large PRDs into manageable specs
• Support for both OpenSpec CLI and GitHub's spec-kit
• Dependency graph analysis and critical path identification
• Quality validation with actionable recommendations and auto-fix
• Seamless integration with OpenSpec workflow

Complete Workflow:

1. Analyze PRD → /openspec:prd-analyze
2. Break down → /openspec:prd-breakdown
3. Review quality → /openspec:spec-review
4. Create proposal → /openspec:proposal (existing)
5. Implement → /openspec:apply (existing)
6. Archive → /openspec:archive (existing)

Usage Examples:

Analyze PRD complexity first:

/openspec:prd-analyze ./requirements.md --detailed

Break down PRD into specs and tasks:

/openspec:prd-breakdown ./docs/PRD.md

Split a large PRD into feature specs:

/openspec:prd-split ./PRD.md --strategy features

Review and validate specifications:

/openspec:spec-review --strict --fix

Use spec-kit instead of OpenSpec CLI:

/openspec:prd-breakdown ./PRD.md --tool speckit

Installation:

/plugin install openspec@claude-code-marketplace

Recommended Dependencies:

# Install OpenSpec CLI (optional but recommended)
npm install -g @fission-ai/openspec@latest

# Or use spec-kit (alternative)
uvx --from git+https://github.com/github/spec-kit.git specify
