Audit a website's HTTP security headers and cookie flags — CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP/COEP, version-leaking banners, and Secure/HttpOnly/SameSite cookies. Use when the user asks to "check my site's security headers", "audit HTTP headers", "is my CSP/HSTS configured right", or "scan a URL for header misconfigs".

HTTP Security Header Audit

Checks a site's response headers against modern web-security best practices and returns prioritized findings with concrete fixes. The analysis core is pure and offline-testable; live scanning uses only Python's stdlib urllib.

When to use this skill

"Audit the security headers on https://example.com."
"Is my CSP / HSTS / cookie config correct?"
"Why is this site flagged for missing headers?"

What it checks

Content-Security-Policy — presence, unsafe-inline, wildcards.
Strict-Transport-Security — presence and max-age length.
X-Content-Type-Options: nosniff, X-Frame-Options / frame-ancestors.
Referrer-Policy, Permissions-Policy.
Information disclosure — Server / X-Powered-By version banners.
Cookies — Secure, HttpOnly, SameSite (incl. SameSite=None without Secure).

How to run it

# Live scan
python skills/http-sec-audit/audit.py https://example.com

# JSON output
python skills/http-sec-audit/audit.py https://example.com --json

# Offline: audit a saved raw header block (no network)
python skills/http-sec-audit/audit.py --headers-file response_headers.txt

Exit codes: 0 no high issues · 1 findings present · 2 fetch/usage error.

Recommended workflow for Claude

Run the audit (live, or offline against captured headers).
Group findings by severity and present each with its one-line fix.
Offer ready-to-paste header snippets for the user's stack (nginx, Apache, Express, etc.) for the missing headers.
Only scan sites the user owns or is authorized to test.

cors-auditor

NovaCode37/claude-security-skills

Audit a site's Cross-Origin Resource Sharing (CORS) configuration for misconfigurations — wildcard origin with credentials, reflected arbitrary Origin, the 'null' origin, overly broad allowed methods, and risky credentialed CORS. Use when the user asks to "check my CORS config", "is my API's CORS safe", "test for CORS misconfiguration", or "why can any site call my API".

dockerfile-scan

NovaCode37/claude-security-skills

Scan a Dockerfile for insecure build patterns — running as root, unpinned or :latest base images, ADD from remote URLs, piping curl/wget into a shell, hardcoded secrets in ENV/ARG, world-writable chmod 777, and sudo usage. Use when the user asks to "review my Dockerfile", "is this container image secure", "lint my Dockerfile for security", or "why does my image run as root".

dependency-check

NovaCode37/claude-security-skills

Audit project dependencies for known-vulnerable versions and risky pinning. Parses requirements.txt and package.json, matches a bundled offline advisory DB, optionally queries OSV.dev live, and warns about unpinned versions. Use when the user asks to "check dependencies for vulnerabilities", "audit my requirements.txt / package.json", "scan for vulnerable packages", or "is my dependency tree secure".

secret-scanner

NovaCode37/claude-security-skills

Scan a codebase for hardcoded secrets — API keys, tokens, private keys and passwords — using a custom regex + Shannon-entropy engine. Use when the user asks to "find secrets", "check for leaked credentials", "scan for API keys", do a pre-commit secret check, or audit a repo before making it public.

prompt-injection-tester

NovaCode37/claude-security-skills

Red-team an LLM application against prompt injection and jailbreaks using a curated, categorized payload library and canary-based detection, then produce a resilience score. Use when the user asks to "test my chatbot for prompt injection", "check if my AI app is jailbreakable", "red-team my LLM", "evaluate prompt-injection defenses", or audit a system prompt's guardrails.

jwt-inspector

NovaCode37/claude-security-skills

Decode and security-audit a JSON Web Token — flag alg=none, missing/excessive expiry, symmetric-alg confusion risk, missing claims — and attempt an offline HMAC secret crack against a wordlist to detect weak signing keys. Use when the user asks to "decode this JWT", "is this token secure?", "audit a JWT", or "check if this token uses a weak secret".
