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 | $0.00032 | $0.01167 |
| Opus 5 | $0.00016 | $0.00583 |
| Sonnet 5 | $0.00006 | $0.00233 |
| Haiku 4.5 | $0.00003 | $0.00117 |
Grade A, and why
multi-tenancy 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 yesterday.
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 — 146 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to use
Use this skill when working with tenant-specific data, customer database connections, or any code that touches the dual-database architecture.
Do NOT use when:
- Single-database applications
- Frontend-only changes
Procedure: Work with multi-tenancy
- Gather context — read
agents/reference/docs/for multi-tenant architecture,config/database.phpfor connection definitions, and search for the tenant switching service. - Identify connection — determine whether the code touches central, tenant, or both databases. Set
$connectionexplicitly on any new model. - Implement — write the feature using the correct connection. Use the tenant switching service for cross-tenant operations. Never mix connections in a single query.
- Verify isolation — inspect the code for tenant leaks: global scopes, missing
$connection, shared caches, or job serialization without tenant context. - Test — write a test that exercises the tenant boundary: seed tenant-specific data, switch context, verify correct data is returned and other tenants' data is invisible.
Architecture overview
Request → Identify Tenant (JWT / subdomain / API key)
→ Lookup credentials from central database
→ Reconfigure tenant connection at runtime
→ All tenant queries use tenant connection
Dual-database pattern
| Connection type | Purpose | Scope |
|---|---|---|
| Central / shared | Global data — tenants, config, shared resources | Shared across all tenants |
| Tenant / customer | Tenant-specific data — domain entities | One per tenant |
The central connection is typically the default connection. The tenant connection starts empty and is configured dynamically per request.

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.

multi-tenancy is a skill published in the GitHub repository event4u-app/agent-config (10 stars, last pushed today), licensed MIT. It adds 32 tokens to every session and 1,167 once invoked, about $0.0002 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 2026-09-04.
