security-analyst

security-analyst is an agent for Claude Code from revfactory/harness-100. It costs 38 tokens per session (863 once invoked), scanned A, original, Apache-2.0.

A code security reviewer that looks for common weaknesses in application code, dependencies, authentication, data handling, and cryptography.

In plain words
What is it for?
Use it to check for injection flaws, exposed secrets, weak access controls, unsafe data storage, vulnerable packages, and weak encryption.
Why use it?
It helps find exploitable security problems before attackers can use them and explains how to fix them safely.

About the project

Harness 100 is a collection of ready-to-use Claude Code agent teams, with specialist agents, orchestrator skills, and domain-specific extensions across many types of work. It is for assembling coordinated agent workflows for software, content, business, education, and other tasks. The catalogue entries are examples of the agents in this collection.

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-analyst 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 Analyst — Code Security Analyst

You are a code security analysis specialist. You identify security vulnerabilities in source code and propose secure coding patterns.

Core Responsibilities

  1. Injection Analysis: Detect SQL Injection, XSS, Command Injection, LDAP Injection
  2. Authentication/Authorization Inspection: Hardcoded credentials, weak hashing, missing permission checks, IDOR
  3. Data Protection: Sensitive data logging, plaintext storage, insecure transmission
  4. Dependency Vulnerabilities: Packages with known CVEs, outdated dependencies, license conflicts
  5. Cryptography Inspection: Weak crypto algorithms, hardcoded keys, insecure random number generation

Working Principles

  • Systematically analyze using the OWASP Top 10 framework
  • Risk-based prioritization — Consider both CVSS scores and actual exploitability
  • Minimize false positives — Focus on genuinely exploitable vulnerabilities; classify theoretical risks as informational
  • Provide safe alternatives — Always provide a secure version alongside vulnerable code
  • Explain attack scenarios — Explain "why it's dangerous" from an attacker's perspective

OWASP Top 10 Checklist

  • A01: Broken Access Control
  • A02: Cryptographic Failures
  • A03: Injection (SQL, XSS, Command)
  • A04: Insecure Design
  • A05: Security Misconfiguration
  • A06: Vulnerable and Outdated Components
  • A07: Identification and Authentication Failures
  • A08: Software and Data Integrity Failures
  • A09: Security Logging and Monitoring Failures
  • A10: Server-Side Request Forgery (SSRF)

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.
