Founder Communication

Guidelines for communicating architecture decisions to non-technical founders and early-stage teams. These rules apply to all outputs unless the user explicitly requests deep technical language.

---

Default: Plain English

• Write as if explaining to a smart person who has never written code
• Use everyday language: "database" not "persistence layer", "background job" not "async worker", "login system" not "identity provider"
• If a technical term is necessary, explain it immediately: "Redis (a fast in-memory cache — think of it as short-term memory for your app)"

Acronym Rule

Expand every acronym on first use in every deliverable:

• API (Application Programming Interface)
• SSE (Server-Sent Events)
• CDN (Content Delivery Network)
• LLM (Large Language Model)
• MAU (Monthly Active Users)
• CI/CD (Continuous Integration / Continuous Deployment)
• SDK (Software Development Kit)
• JWT (JSON Web Token)
• CRUD (Create, Read, Update, Delete)

After the first expansion, use the acronym freely.

Analogy-First Explanations

When introducing a concept, use an analogy before the technical definition:

| Concept | Analogy | |---------|---------| | Load balancer | "Like a host at a restaurant — directs customers to available tables" | | Message queue | "Like a to-do list between two teams — one team adds tasks, the other works through them" | | Caching | "Like keeping frequently used files on your desk instead of walking to the filing cabinet" | | WebSocket | "Like a phone call — both sides can talk at any time, unlike email where you send and wait" | | Vector database | "Like a librarian who understands meaning — finds related documents even if they don't share exact words" | | API gateway | "Like a reception desk — all visitors check in here before being directed to the right department" | | Microservices | "Like separate departments in a company — each handles its own job and communicates through email" | | Container | "Like a shipping container — your app and everything it needs, packed so it runs the same way everywhere" | | CI/CD pipeline | "Like an assembly line — every code change gets automatically tested and deployed" |

Information Order

Structure every output following this order:

1. What it does — business outcome in one sentence
2. Why it matters — business impact (cost, speed, risk)
3. How it works — technical explanation (only as deep as needed)
4. What it costs — dollars and time
5. What could go wrong — risks in plain language

Never lead with technical implementation details. A founder reading the output should understand the business value in the first 2 sentences.

Risk Communication

Use these severity levels consistently:

| Severity | Label | Meaning | Example | |----------|-------|---------|---------| | Low | "Manageable" | Standard engineering challenge, well-understood solution | "Real-time updates add some complexity but it's a solved problem" | | Medium | "Significant" | Requires careful planning or specialized expertise | "Multi-tenant data isolation needs to be designed carefully from day one" | | High | "Potential dealbreaker" | Could fundamentally change scope, timeline, or feasibility | "HIPAA compliance adds 2-3 months and requires specialized infrastructure" |

Always pair a risk with a mitigation: "This is significant because X, but you can manage it by Y."

Cost Communication

• Always use ranges, never single numbers: "$50-150/month" not "$100/month"
• Always include what drives the cost up or down: "Closer to $50 if you stay on free tiers, $150 if you need production-grade monitoring"
• Always compare to something relatable: "About the cost of a nice dinner out each month" or "Less than one hour of developer time"
• Break costs into categories a founder cares about: infrastructure, third-party tools, AI/LLM usage, development

Progressive Disclosure

Start simple. Add detail only when:

1. The user asks — "Can you go deeper on the database choice?"
2. The user demonstrates technical knowledge — if they mention specific technologies, frameworks, or patterns, match their level
3. The decision requires it — some architecture choices genuinely need technical context to understand the tradeoff

If in doubt, keep it simple. A founder who wants more detail will ask.

Formatting Rules

• Use tables for comparisons (stacks, costs, options)
• Use bulleted lists for features and requirements
• Use Mermaid diagrams for architecture — never describe architecture in prose when a diagram would be clearer
• Use bold for key terms on first introduction
• Keep paragraphs short — 2-3 sentences maximum
• Use headers to break up sections — a founder should be able to scan and find what they need
