Build Software
the AI-Native Way

You say what you want to build. A built-in Requirements Skill — pre-loaded with software engineering knowledge — guides you through a structured conversation: goals, user pain points, scenarios, acceptance criteria. When the dialogue ends, a complete requirements document is ready. No templates to fill. No fields to remember.

A Design Skill reads your requirements and generates a lightweight HTML prototype. Preview it side-by-side with the spec, add inline comments to request changes, and confirm the interaction model is right — before AI writes a single line of business logic. Misunderstandings caught here cost nothing.

A Scenario Skill reads your product design and generates sequence diagrams for every user flow — which actor calls which API, in what order, with what edge cases. Scenarios are the backbone of the Spec Chain: every downstream artifact — API contracts, DB schema, test cases — derives from them. No scenario means no traceability.

An API Skill reads your scenario diagrams and generates a complete OpenAPI specification. Every endpoint traces back to a scenario step — AI doesn't guess the interface, it reads the contract. The visual editor lets you review and refine before any code is written.

A Schema Skill reads your API contracts and derives the data model. Define table structures visually — SQLite, PostgreSQL, or MySQL — and export DDL. The schema is not designed in isolation: it is deduced from what the API needs to store and retrieve.

A Test Skill reads your scenarios and generates unit and integration test cases. Chain multi-step API scenarios in a visual flow builder, run them against your actual server, and assert every response. Tests are written before code — so the acceptance criteria are locked in before AI generates anything.

Hand the complete Spec Chain to AI in one pass: requirements, prototype, scenarios, API contracts, DB schema, test cases. Because nothing is missing, the output is accurate — no hallucinated endpoints, no guessed table names, no missing edge cases. The code is generated against a contract, not a conversation.

Run openlogos verify and get a full traceability report — every requirement traced to every test case, with pass rate, coverage, and gate result. Not just "tests passed." Every acceptance criterion from Phase 1 is accounted for. Ship with proof.

After launch, every feature change or bug fix starts with a Delta proposal — not a direct code edit. Describe what changes and why, identify which scenarios, APIs, and DB tables are affected, and let AI propagate the change through the Spec Chain before touching the code. The history is always intact.
