Spec Iterator is an MCP server published by JesseHenson in the Blockchain category: # Stop Building Features Based on Assumptions **Spec Iterator** conducts structured AI-powered clarification sessions that systematically uncover gaps in your requirements *before* you write code. --- ## The Problem Everyone Ignores ``` Stakeholder: "Build a dashboard for our sales team" ↓ You build it ↓ Stakeholder: "Where's the pipeline view?" ↓ You: "You didn't mention that" ↓ Stakeholder: "I assumed it was obvious" ↓ 💸 2 weeks of rework ``` **Requirements arrive incomplete.** Stakeholders don't know what they don't know. The "obvious" features only become obvious after you ship the wrong thing. --- ## How Spec Iterator Works ``` ┌─────────────────────────────────────────────────────────────┐ │ "We need order tracking for customers" │ └─────────────────────────────────────────────────────────────┘ ↓ ┌─────────────────────────────────────────────────────────────┐ │ 🔍 ANALYZE │ │ ───────────────────────────────────────────────────────── │ │ • Entities detected: orders, customers, tracking │ │ • Gaps found: users undefined, stages unclear, no UX │ │ • Completeness: 12% │ └─────────────────────────────────────────────────────────────┘ ↓ ┌─────────────────────────────────────────────────────────────┐ │ ❓ CLARIFY (Round 1) │ │ ───────────────────────────────────────────────────────── │ │ 1.

Order Status Page (MVP) Customers can view real-time order status on a dedicated page. **Acceptance Criteria:** - [ ] Display order stages: Confirmed → Processing → Shipped → Delivered - [ ] Show estimated delivery date - [ ] Update within 5 minutes of status change - [ ] Accessible without login via order ID + email ### 2. Email Notifications (MVP) Automated emails at key order milestones. **Acceptance Criteria:** - [ ] Send on: order confirmed, shipped, out for delivery, delivered - [ ] Include tracking link when available - [ ] Unsubscribe option per notification type ## Edge Cases | Scenario | Handling | |----------|----------| | Order stuck in "Processing" > 48h | Trigger support alert | | Tracking number not yet available | Show "Tracking available soon" | | Multiple shipments per order | Show each shipment separately | ``` --- ## Who It's For **Product Managers** → Stop missing requirements that cause rework **Tech Leads** → Don't estimate incomplete requirements **Solo Developers** → Think through requirements systematically **Startup Founders** → Document ideas with implementation detail **Consultants** → Standardize discovery across clients --- ## Configuration Requires your Anthropic API key: | Parameter | Description | |-----------|-------------| | `ANTHROPIC_API_KEY` | Your Anthropic API key | **You pay Claude directly** — typical spec costs $0.05-0.15 in API usage (3-5 rounds of clarification). --- ## Quick Start 1. **Connect** Spec Iterator in Claude Desktop 2. **Run:** `spec_start_session` with your rough requirement 3. **Answer** the clarifying questions 4. **Generate** when completeness hits 80%+ --- ## Resources - **GitHub:** [Repository](https://github.com/JesseHenson/claude_code_apex_marketplace/tree/master/plugins/spec-iterator-mcp) - **Demo:** Coming soon - **Support:** Open an issue on GitHub --- ## Version **v0.1.0** — Initial release - Multi-turn clarification flow - Completeness scoring (5 categories) - Markdown and JSON output - Session persistence Site: https://aibusinessautomation.solutions/.

Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.
