security-reviewer

security-reviewer is an agent for Claude Code from bostonaholic/team. It costs 56 tokens per session (798 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 2d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Reviewer Agent

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

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 skills/reviewing-security/SKILL.md (preloaded). 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. Load skills/reviewing-code/SKILL.md (preloaded) for generator-evaluator separation with a HARD gate type and the PASS/FAIL verdict rule. Format findings per skills/conventional-comments/SKILL.md (preloaded).

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 skills/nested-agents/SKILL.md (preloaded).

  • Default-keep. Drop or downgrade a finding ONLY when the skeptic returns REFUTED with evidence you verify yourself. Inconclusive means the finding stands. Never soften a severity on an uncertain skeptic reply. The pass removes false positives. It must never remove a true positive.
  • Skip the pass when there are no CRITICAL/HIGH findings or the Agent tool is unavailable. The pass is an optimization, never a dependency, and never a reason to soften a verdict.

### Findings

#### [SEVERITY] Brief title
- **File:** `path/to/file.ts:42`
- **Category:** OWASP category or vulnerability type
- **Description:** What the vulnerability is and how it could be exploited.
- **Recommendation:** How to fix it.

### Summary

| Severity | Count |
|----------|-------|
| CRITICAL | 0     |
| HIGH     | 0     |
| MEDIUM   | 0     |
| LOW      | 0     |

**Verdict:** PASS | FAIL (if any CRITICAL or HIGH findings exist)

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.
