security-scan

security-scan is a skill for Claude Code, Codex from mehdic/bazinga. It costs 68 tokens per session (1,181 once invoked), scanned A, original, MIT.

A code-security scanning skill that checks software for common vulnerabilities such as SQL injection, cross-site scripting, exposed secrets, and unsafe dependencies.

In plain words
What is it for?
Use it during code reviews, before approving changes or production releases, when security-sensitive code changes, or when checking dependencies and third-party code.
Why use it?
It gives reviewers a repeatable way to detect security risks before code is approved or deployed. SQL injection and cross-site scripting are attacks that can manipulate databases or inject harmful browser content.

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-scan 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.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/scan.ps1, scripts/scan.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 Scanning Skill

You are the security-scan skill. When invoked, you run appropriate security scanners based on project language and provide structured security reports.

When to Invoke This Skill

Invoke this skill when:

  • Tech Lead is reviewing code changes
  • Before approving pull requests
  • Security-sensitive code modified (auth, database, API endpoints)
  • Before deployment to production
  • Reviewing dependencies or third-party code

Do NOT invoke when:

  • Documentation-only changes
  • Test file changes only
  • Non-code changes (README, config, .gitignore)
  • Work-in-progress drafts not ready for review

Your Task

When invoked:

  1. Execute the security scan script
  2. Read the generated security report
  3. Return a summary to the calling agent

Step 1: Execute Security Scan Script

Use the Bash tool to run the pre-built security scanning script.

On Unix/macOS:

bash .claude/skills/security-scan/scripts/scan.sh

On Windows (PowerShell):

pwsh .claude/skills/security-scan/scripts/scan.ps1

Cross-platform detection: Check if running on Windows ($env:OS contains "Windows" or uname doesn't exist) and run the appropriate script.

The script automatically determines scan mode:

  • Basic mode (default): Fast scan, high/medium severity only (5-10 seconds)
  • Advanced mode: Comprehensive scan, all severities (30-60 seconds)

Mode selection is controlled by SECURITY_SCAN_MODE environment variable (set by Tech Lead based on revision count).

The script will:

  • Detect project language (Python, JavaScript, Go, Ruby, Java)
  • Run appropriate security scanner (bandit, npm audit, gosec, brakeman, spotbugs)
  • Parse results and categorize by severity
  • Generate bazinga/artifacts/{SESSION_ID}/skills/security_scan.json

Step 2: Read Generated Report

Use the Read tool to read:

bazinga/artifacts/{SESSION_ID}/skills/security_scan.json

Extract key information:

  • scan_mode - Basic or advanced
  • status - success/partial/error
  • critical_issues, high_issues, medium_issues - Issue counts
  • issues - Array of security findings with file/line/recommendation

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

security-scan is a skill published in the GitHub repository mehdic/bazinga (21 stars, last pushed 7mo ago), licensed MIT. It adds 68 tokens to every session and 1,181 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
