PRD: Unified Authentication Service

FieldValue
StatusDraft

1. Context

We're standardizing login across all Acme products to reduce friction and support seamless passwordless sign-in for enterprise customers.

Constraint:The first release must support magic-link email login only (zero passwords allowed) to minimize security surface area and accelerate rollout to SOC2 clients.

2. User Journey

  • User opens the web app and chooses Sign Up
  • User enters an authorized email address
  • Auth System emails a secure magic link (2FA enforced)
  • User clicks the magic link and lands directly in their dedicated workspace

"Just put it in Notion"

  • Docs are disconnected from code
  • Diagrams are just static PNGs
  • No standard structure or schema
  • Eventually, nobody trusts the docs

Capture truth once.

Stable Baseline helps you capture how things really work (from people, meetings, and docs) and turns it into structured outputs engineers can use — specs, BPMN, and technical diagrams — all versioned and maintainable.

One source of truth that stays true, updated by AI agents directly from your codebase.

The Developer Workflow

Stable Baseline MCP provides your AI coding assistant with 34 specialized tools to understand, generate, and maintain your architecture diagrams and documentation inline.

1. Connect

Add the MCP server config to your IDE. This gives your AI agent "tools" to read and write documentation.

2. Onboard

Run the setup prompt. Your agent scans the codebase and generates a complete documentation site + diagrams in one go.

3. Maintain

Made changes? Ask your agent to update the docs mid-conversation. It captures your decisions and updates instantly.

AUTONOMOUS AGENT

Docs that write themselves.

Our platform includes an extremely powerful built-in agent that automatically keeps your documentation up to date. It retrieves knowledge, pinpoints update locations, and dynamically inserts and renders diagrams—without any manual prompt or command.

Use it as a standalone tool, or connect it via MCP to your popular IDEs (Cursor, Windsurf, VS Code) and chat agents like Microsoft Copilot Studio.

Done! I've inserted a summary at the top of your document. It includes:

  • A brief overview of what the document contains
  • A list of the diagram types present (Systems Architecture, BPMN, and SVG Bob)
  • A separator line to distinguish it from the original content

Visual Truth. Rendered Instantly.

Stable Baseline goes beyond text. Agents write standard markdown with embedded standard diagram DSL blocks (Mermaid, PlantUML, BPMN), and our platform renders it natively into an interactive viewer.
