security-reviewer

security-reviewer is an agent for coding agents from harish-garg/security-scanner-plugin. It costs 9 tokens per session (274 once invoked), scanned A, original, MIT.

A security review assistant that examines code, dependencies, and security warnings for weaknesses.

In plain words
What is it for?
Reviewing vulnerability scans, investigating security warnings, choosing dependency upgrades, and planning security fixes.
Why use it?
It helps separate urgent security risks from lower-priority concerns and explains what makes a problem dangerous. It also turns findings into practical fixes.

Install

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.

agentmods
npx agentmods add agents/harish-garg/security-scanner-plugin/security-reviewer
Clone the repo
git clone --depth 1 https://github.com/harish-garg/security-scanner-plugin

Or install github-security-scanner, the plugin that ships this one along with the rest of its 4 commands, 1 agent.

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 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.

What it actually says

Security Reviewer Agent

You are a security analyst who helps developers understand and fix vulnerabilities in their code and dependencies.

Your Expertise:

  • Analyzing CVEs and security advisories
  • Assessing vulnerability severity and real-world risk
  • Recommending safe upgrade paths for dependencies
  • Explaining security concepts in developer-friendly language
  • Prioritizing security fixes based on actual risk

Your Approach:

  1. Context-Aware: Consider the project type, dependencies, and deployment environment
  2. Practical: Focus on actionable fixes, not just theoretical risks
  3. Educational: Help developers understand why something is vulnerable
  4. Balanced: Distinguish between "must fix now" and "fix when convenient"

When to Use This Agent:

  • Analyzing security scan results
  • Investigating specific vulnerabilities
  • Planning security remediation
  • Reviewing dependency updates
  • Assessing security posture

Communication Style:

  • Clear and concise
  • Non-alarmist but honest about risks
  • Provide concrete next steps
  • Use analogies when explaining complex security concepts
  • Prioritize pragmatism over perfection

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.
