What is 08-stack-web-default?

A default technology choice for new web projects: Node.js with Firebase for the backend, database, authentication, and hosting-related services.

It helps plan web apps, dashboards, APIs, authentication, databases, deployments, and MVPs.

It gives web work a starting architecture while allowing the existing repository or an explicit user choice to take priority.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00027	$0.00876
Opus 5.5	$0.00011	$0.00350
Sonnet 5.5	$0.00005	$0.00175
Haiku 4.5	$0.00003	$0.00088

Security

Grade A, and why

08-stack-web-default scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stack web canónico (Firebase + Node)

Fuente de datos: vitals/data/engineering/web-stack.yaml. Override local opcional: .agents/engineering-stack.md.

Cuándo aplica

Activar esta regla cuando el pedido implique desarrollo web o arquitectura de producto web:

App web, SPA, dashboard, admin panel
Landing con backend o autenticación
API REST/HTTP para cliente web o mobile
MVP, PRD o SRD con componente técnico web
Deploy, auth, base de datos o hosting para producto web

No aplica como stack DB/backend cuando: solo diseño Atelier sin implementación; video Remotion; tareas puramente de docs/marketing sin código.

Precedencia (soft default)

Resolver en este orden (mayor prioridad primero):

Opt-out explícito del usuario — respeta la elección; documenta trade-offs si difiere del default.
Stack del repo existente — inspeccionar señales antes de proponer migración:
- firebase.json, firestore.rules, firestore.indexes.json
- package.json (dependencias firebase, vite, react)
- requirements.txt, go.mod, Cargo.toml, docker-compose con Postgres/MySQL
- README o docs de arquitectura del proyecto
.agents/engineering-stack.md — si existe, usar como stack confirmado del proyecto.
Default DT — web-stack.yaml: Node + Firebase completo; frontend Vite + React.

Si el repo ya tiene stack claro distinto (p. ej. Python/Django + Postgres), respetarlo. Mencionar el default DT solo como nota, no empujar migración.

Stack default (proyecto nuevo o ambiguo)

Capa	Default
Runtime	Node.js LTS
Auth	Firebase Auth
Base de datos	Firestore
Backend/API	Cloud Functions for Firebase (Node)
Hosting	Firebase Hosting / App Hosting
Archivos	Cloud Storage
Secrets	Firebase Secrets
Frontend	Vite + React (Firebase JS SDK modular v9+)

Alternativas (Supabase, Postgres, Python, etc.): solo proponer con trade-offs explícitos y después de opt-out del usuario o cuando el repo ya las usa.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
