Security checklist covering XSS, injection, authentication, authorization, sessions, CSRF, CSP, secrets, dependency CVEs, input validation, and severity calls. Use when writing or reviewing code that handles auth, sessions, secrets, user input, or external data, or when the user asks about security, hardening, vulnerabilities, authentication, authorization, cookies, XSS, CSRF, SQL injection, CSP, or headers, even if "security" is not mentioned by name. Not loaded just because a project has such code.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

Security patterns
Apply the references that match the detected stack. Severity rubric below applies cross-cuttingly.
Severity rubric
failure: exploitable, or direct leak of credentials, or missing CSRF on authenticated mutating endpoint.warning: mitigated but weak (e.g. CSP present but withunsafe-inline), or pattern that will become exploitable if misused.info: hardening opportunity, not currently exploitable.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
