What is security-check?

A broad security scanning suite for code and related project files. It combines vulnerability checks, language-specific reviews, dependency and supply-chain checks, infrastructure configuration checks, and report generation.

It is for running full security audits, reviewing code changes, scanning for vulnerabilities, checking dependencies and infrastructure settings, and filtering findings by severity.

It gives a coding assistant a structured way to look for security problems across an application rather than checking only one file or vulnerability type.

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.

Any agent

npx skills add fatihkan/badi --skill security-check

Clone the repo

git clone --depth 1 https://github.com/fatihkan/badi

Made for: Claude Code.

Or install badi, the plugin that ships this one along with the rest of its 81 skills, 86 commands, 30 agents, 7 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00091	$0.01419
Opus 5	$0.00046	$0.00709
Sonnet 5	$0.00018	$0.00284
Haiku 4.5	$0.00009	$0.00142

Security

Grade A, and why

security-check 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 today.

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.

Your AI Becomes a Security Team. Every Language. Every Layer. Zero Tools.

Entry points (v1.31.0+):

/security-review — Anthropic native command (Claude Code 2.1.140+, AI semantic)

badi security baseline — deterministic baseline (secret-scan + audit)

badi security triage — /security-review report severity filtering

This skill: sc-orchestrator 4-phase pipeline (Recon → Hunt → Verify → Report)

What This Skill Does

security-check transforms your AI coding assistant into a comprehensive security scanning team. It runs a 4-phase pipeline — Recon → Hunt → Verify → Report — entirely through natural language. No binaries, no dependencies, no CI pipeline changes.

Quick Start

After installation, open your AI assistant and say:

"run security check" — Full security audit
"scan diff" — PR/diff-level incremental scan
"scan for vulnerabilities" — Same as full scan

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-check is a skill published in the GitHub repository fatihkan/badi (7 stars, last pushed yesterday), licensed MIT. It adds 91 tokens to every session and 1,419 once invoked, about $0.0005 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 2026-09-06.

issue-triage

3-phase issue backlog management with audit, deep analysis, and validated triage actions. Use when triaging GitHub issues, sorting bug reports, cleaning up stale tickets, or detecting duplicate issues. Args: 'all' to analyze all, issue numbers to focus (e.g. '42 57'), 'en'/'fr' for language, no arg = audit only.
