What it does

Better Auth Security Best Practices is an agent skill from viclafouch/meme-studio. This skill provides guidance for implementing security features that span across Better Auth, including rate limiting, CSRF protection, session security, trusted origins, secret management, OAuth security, IP tracking, and security auditing. These topics are not covered in individual plugin skills.

Its SKILL.md is about 4.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Secrets management, Rate limiting and Web application vulnerabilities. It works with Better Auth. The repository describes itself as: 📌 A complete and fast website building in Next.js for creating and sharing "internet memes".

When your agent uses it

Example prompts

Requirements

A credential in BETTER_AUTH_SECRET
A credential in AUTH_SECRET

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

AUTH_SECRET environment variable

What it can do on your machine

Read from SKILL.md and the folder at commit d8fa0be. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- openssl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names these keys or tokens, usually read from environment variables:
- BETTER_AUTH_SECRET
- AUTH_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Better Auth Security Best Practices loads about 4.2k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 1,110 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~84
When it runs · the whole SKILL.md, loaded when a task matches: ~4.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,110 words (~4,158 tokens).

“The auth secret is the foundation of Better Auth's security. It's used for signing session tokens, encrypting sensitive data, and generating secure cookies.”
