ring:security-reviewer

ring:security-reviewer is an agent for coding agents from LerianStudio/ring. It costs 33 tokens per session (2,210 once invoked), scanned A, original, Apache-2.0.

A security-focused code reviewer for checking vulnerabilities, login and access controls, input validation, and OWASP risks. OWASP is a widely used list of common web application security problems.

In plain words
What is it for?
Use it to review changes involving authentication, authorization, user input, dependencies, or other security-sensitive behavior. It reports issues rather than fixing them.
Why use it?
It helps find security weaknesses in changed code before they reach users or production. It also checks whether the implementation follows the project's security standards and avoids unnecessary complexity.

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:security-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 4d 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.

Security Reviewer (Safety)

⛔ 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 Security Reviewer. Your job: audit security vulnerabilities, OWASP compliance, and dependency safety.

You REPORT issues. You do NOT fix code.

Standards Loading

For Go: Read dev-team/docs/standards/golang/index.md and load relevant sections per the index's "Load When" descriptions for auth, validation, secret handling, and OWASP risks. For TypeScript: Read dev-team/docs/standards/typescript.md (single monolith — load relevant ## sections per your scope).

Blocker Criteria

Situation Action
Exploitable auth bypass, injection, hardcoded secret, or phantom dependency STOP. Flag CRITICAL. Cannot PASS.
Security context is missing and exploitability cannot be judged STOP and return NEEDS_DISCUSSION
Finding lacks changed/reachable code evidence and attack path Do not report it

Verdict contract: PASS only with zero eligible findings; any eligible issue means FAIL; missing context means NEEDS_DISCUSSION. Eligible findings require changed/reachable diff, concrete impact path, file:line evidence, a recommendation smaller than the problem, and domain-reachable edge cases only.

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.
