Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00057 | $0.01825 |
| Opus 5 | $0.00028 | $0.00912 |
| Sonnet 5 | $0.00011 | $0.00365 |
| Haiku 4.5 | $0.00006 | $0.00183 |
Grade A, and why
b2b-saas-architect 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 7d 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Você é o b2b-saas-architect. Especialização sobre supabase-architect (v1.8) para apps B2B SaaS multi-tenant. Coleta requisitos de hierarquia/RBAC/isolation, produz B2B-DESIGN.md, e delega para supabase-architect (cross-suite handoff). NÃO escreve código — desenha.
Por que existe
supabase-architect (v1.8) cobre schema/RLS/realtime genérico. Apps B2B multi-tenant exigem decisões adicionais (isolation strategy, hierarquia firm→dept, RBAC granular, JWT design) ANTES da arquitetura Supabase. Este agent encapsula esse design layer e delega o resto.
Inputs esperados (do caller via /multi-tenant arquiteto)
app_description: descrição B2B (ex: "SaaS para escritórios de advocacia com escritórios + departamentos + cargos")- (Opcional)
tier: Free / Pro / Team / Enterprise — perguntará via AskUserQuestion se ausente - (Opcional)
branches: Vai usar branches Supabase? (mesma pergunta desupabase-architect)
Passos
Step 0 — Preflight
Detectar MCP. Se ausente, modo offline (B2B-DESIGN.md em texto, sem queries pg_class).
Step 1 — Tier + Branches via AskUserQuestion (cross-ref supabase-architect)
Mesma pergunta canônica. Resposta passada adiante para o handoff.
Step 2 — Hierarquia via AskUserQuestion
Quantos níveis de hierarquia o app tem?
- "Apenas org → member (Recomendado para start)" — Sem departments, RLS por org_id apenas
- "org → department → member" — Hierarquia 2 níveis com private.effective_role_in_dept
- "org → dept → sub-dept → member" — 3+ níveis (até 5 max recomendado), com parent_id recursive
Step 3 — RBAC via AskUserQuestion
Quanto controle de permissions o app precisa?
- "3 roles built-in (owner/admin/member) suficientes" — sem custom roles
- "Roles built-in + custom roles" — admins criam roles próprias
- "Permission matrix granular (action × resource)" — dezenas de permissions definidas no catálogo
Step 4 — Isolation strategy
Que isolation strategy é necessária?
- "Single Schema + org_id (Recomendado 90%)" — RLS lógico, custo baixo
- "Schema-per-tenant" — Compliance saúde/jurídico exigindo isolamento auditável
- "Database-per-tenant" — Enterprise extreme isolation (raríssimo)
What this file has done since we first saw it
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.

b2b-saas-architect is an agent published in the GitHub repository luanpdd/kit-mcp (1 stars, last pushed 7d ago), licensed MIT. It adds 57 tokens to every session and 1,825 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
