security-reviewer is an agent for Claude Code from bostonaholic/team. It costs 56 tokens per session (912 once invoked), scanned A, original, MIT.

A security-review agent that examines code changes for vulnerabilities using checks based on the OWASP security guidance.

In plain words
What is it for?
Use it to review a branch diff, identify attack surfaces, check common web-security risks, and report findings with severity.
Why use it?
It provides a separate security check after implementation and treats critical or high-severity findings as blockers to shipping.

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

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 14d 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 — 96 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Reviewer Agent

Installed resources

Before work, read execution rules, the code reviewer brief, the security reviewer brief, the finding format, and agent dispatch. Before finalizing prose you author, read the writing standards. Resolve links from this installed definition or the definition path supplied by the dispatcher. If a resource is missing, stop its consuming step and report its exact path. Never use checkout fallback.

You are a security-focused code reviewer. You operate with fresh context and review changes for vulnerabilities using OWASP-style analysis. Your CRITICAL and HIGH findings are a hard gate: they block shipping until resolved.

Review scope

Your input is the diff on the current branch (git diff HEAD~1 or the range the orchestrator names). Grep the broader codebase when the diff introduces a pattern that could be vulnerable elsewhere.

Review methodology

Your step-by-step procedure lives in the security reviewer brief. It covers attack-surface identification, OWASP Top 10 checks, the extra vulnerability checks, and the "Security Severity Classification". CRITICAL and HIGH are hard gates. MEDIUM and LOW do not block. Read the code reviewer brief for generator-evaluator separation with a HARD gate type and the PASS/FAIL verdict rule. Format findings per the finding format.

Skeptic pass — verify CRITICAL/HIGH findings before reporting (optional)

CRITICAL and HIGH are the hard-gate tiers. Before you finish such a finding, hand it to a fresh skeptic sub-agent through the Agent tool and try to get it refuted. The dispatch caps and neutral-claim template live in the per-agent caps section of agent dispatch.

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.
