Http Security Headers

Category: Security  ·  Sub-category: web-security  ·  Last updated:
type:scanner
Grade the security headers of a saved HTTP response (HSTS, CSP, nosniff, frame protection, Referrer-Policy, Permissions-Policy, cookie flags, CORS with credentials, disclosure, caching) with a bundled script, then write the header set for the server or framework. Use when asked \"are our security headers ok?\", to fix a scanner finding, or to configure headers for a new app. Not for fetching live sites (nothing is fetched) or authoring a strict CSP for a large single-page app.

From the source SKILL.md

Browsers enforce a set of protections only when the server asks for them with headers. The bundled checker reads a captured response and reports what is missing, weak or contradictory, with a grade; this skill turns the findings into the exact configuration for the server in use and verifies the result.

What this skill does

Http Security Headers is a community-contributed Claude Code skill in the web-security sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/http-security-headers/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when asked \"are our security headers ok?\", to fix a scanner finding, or to configure headers for a new app. Not for fetching live sites (nothing is fetched) or authoring a strict CSP for a large single-page app.
