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 | $0.00378 | $0.00378 |
| Opus 5 | $0.00189 | $0.00189 |
| Sonnet 5 | $0.00076 | $0.00076 |
| Haiku 4.5 | $0.00038 | $0.00038 |
Grade A, and why
004-multi-tenancy-pattern 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 3d 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.
What it actually says
Soft Multi-Tenancy (MVP)
⚠️ EXAMPLE DOMAIN (AI hiring/recruiting) — NOT this project's rules. This file is a portable example of a soft multi-tenancy pattern. Its specifics (
jobs,applications,interview_recordings, CVs, HR/candidate roles) do not describe the current project. Agents: ignore the domain specifics below until this file is replaced with the real tenancy model for<PROJECT>(seeAGENTS.md §4). Delete or rewrite on port.
Details: AGENTS.md §4. Application-level isolation, no RLS in MVP.
tenant_id Rules
- Has tenant_id:
users(nullable),jobs,applications,interview_recordings,audit_logs - No tenant_id:
cvs,cv_versions,skills,consents(global/candidate-owned) - Candidates:
tenant_idNULL; HR:tenant_idNOT NULL; Admin users: NULL
Application Isolation
TenantContextGuard+@TenantId()on tenant-scoped queries- HR queries MUST filter
tenant_id; no cross-tenant access on app API - Admin service: cross-tenant read-only for analytics
Tenant Lifecycle
- Auto-create tenant on HR register:
plan=free,max_users=5,max_jobs=3,max_ai_credits=100 - Reject if
tenant.status != 'active'; soft limits →403with upgrade prompt
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.
