🌐 t3-stack × web-service

Ship web service / api on T3 Stack without losing weeks to compliance.

T3 Stack is a TypeScript natural fit for web service / api. GreatCTO auto-detects both — adds the web-service archetype overlay, wires web-service-specific gates, and runs 34 specialist agents around your existing T3 Stack workflow.

$ npx great-cto init 🌐 See archetype →

What changes when GreatCTO joins your T3 Stack project

Detection → overlay → gates → reviewers.

1 · DETECT

Stack + archetype

GreatCTO reads your package.json and detects t3-stack + web-service archetype from signals: imports, file structure, env vars, README hints.

2 · OVERLAY

Archetype pack

Attaches the web-service archetype overlay: OWASP API Top-10, GDPR data-minimization, SLO + error-budget gates. Override if your specifics differ; the defaults are sensible for T3 Stack-style projects.

3 · GATES

T3 Stack-aware reviewers

qa-engineer runs tsc --strict / eslint / vitest --coverage; security-officer checks for prototype pollution + XSS sinks; performance-engineer reviews bundle size + cold-start times.

4 · MEMORY

Cross-project lessons

Bugs you've hit before in other T3 Stack projects (connection-pool exhaustion, ORM N+1 queries, retry storms) — the agent's Step 0 includes the prior detection order. MTTR drops 94 % on second occurrence (methodology).
