Real Builds, Real Numbers
Case Studies
Two looks at NEXUS OS in action — a complete feature delivered end-to-end with a perfect MergeGate score, and the broader validation campaign that measured NEXUS against traditional development across 8 codebases.
End-to-End Todo App Build
A complete task-management app — auth, CRUD API, database schema, React UI, and tests — delivered by the full Orchestrator → ComponentAgent → SubAgent → AtomicAgent hierarchy in a single Forge run.

Delivery Timeline
Plan
Orchestrator decomposed the spec into 22 typed tasks across frontend, backend, database, and E2E ComponentAgents — fully dependency-ordered.
Build
Each ComponentAgent dispatched SubAgents and AtomicAgents for its slice — CRUD API routes, React components, schema migrations, and auth — routed across haiku/sonnet/opus by CORTEX.
Validate
Automated tests were generated alongside implementation code. A real E2E smoke test exercised the create → complete → delete flow end-to-end in a live environment.
Ship
MergeGate scored the full delivery at 100/100 across all five quality axes — tests, security, efficiency, self-correction, and constitution — and merged automatically.
NEXUS vs. Traditional Development
Paired pilots across 8 different codebases — each task delivered once traditionally and once via NEXUS OS, with identical scope and acceptance criteria, then measured before/after.

Security AutoFix (cmd-injection)
Each pilot was run twice — once with traditional, human-only delivery and once with NEXUS OS — for a total of 22 measured runs. Time, token, and cost deltas are normalized against the traditional run as the 100% baseline.
