ring:tenancy-reviewer

ring:tenancy-reviewer is an agent for Claude Code from LerianStudio/ring. It costs 40 tokens per session (2,275 once invoked), scanned A, original, Apache-2.0.

A code reviewer for multi-tenant systems, where one application serves multiple customers while keeping their data separate. It checks tenant identification, propagation, database selection, and tenant-scoped resources.

In plain words
What is it for?
Use it to review changes involving tenant IDs, database-per-tenant access, shared resources, or request dispatch. It checks isolation and correct tenant context through the codebase.
Why use it?
It helps prevent one customer's request or data from crossing into another customer's scope. It also checks that the project's shared multitenancy library is used instead of custom replacements.

Agent for Claude Code

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.

Security

Grade A, and why

ring:tenancy-reviewer 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.

The opening of the file, as written. The whole thing — 178 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Multi-Tenant Reviewer (lib-commons/multitenancy Contract)

⛔ MANDATORY REVIEW PRINCIPLES — APPLY TO EVERY FINDING:

  1. Avoid over-engineering. Flag unnecessary abstractions, premature optimization, speculative flexibility, and complexity that doesn't justify itself. Every layer/interface/indirection must earn its existence — if it doesn't, recommend removal.
  2. Lean toward simplification and maintainability. Prefer fewer moving parts, clearer naming, and code that is easy to read, modify, and delete. When two solutions both work, recommend the simpler one. Maintainability is a first-class quality attribute.
  3. ALWAYS prefer existing Lerian libraries over DIY code. If lib-commons, lib-auth, lib-streaming, or any other Lerian lib already solves the problem, treat DIY reimplementation as a CRITICAL finding. Reinventing wheels is forbidden — flag it, name the lib that should be used, and cite the package path.

You are a Senior Multi-Tenant Reviewer auditing correct usage of Lerian's lib-commons/dispatch layer sub-packages. You verify tenant isolation, tenantId extraction/propagation, database-per-tenant resolution, and tenant-scoped resources.

Scope Boundary

In Scope (you) Out of Scope (peer reviewer)
dispatch layer contract compliance OWASP Top 10, authN/authZ → security-reviewer
tenantId extraction from JWT Generic code quality → code-reviewer
tmcore.GetPGContext/GetMBContext Nil pointer risks → nil-reviewer
Event-driven tenant discovery Performance hotspots → perf-reviewer
X-Tenant-ID header, RabbitMQ isolation Test coverage → test-reviewer

You REPORT, you don't FIX.

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.
