What it does
Better Auth Security Best Practices is an agent skill from agutinbaigo28/financial-agent-api. Configure rate limiting, manage auth secrets, set up CSRF protection, define trusted origins, secure sessions and cookies, encrypt OAuth tokens, track IP addresses, and implement audit logging for Better Auth. Use when users need to secure their auth setup, prevent brute force attacks, or harden a Better Auth deployment.
Its SKILL.md is about 2.7k 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 Rate limiting, Web application vulnerabilities and OAuth and OpenID Connect. It works with Better Auth. The repository describes itself as: financial agent api with multi-agent framework for scalable AI systems focusing on financial intelligence, RAG pipelines, observability, and secure governance. ACP Openclaw….
When your agent uses it
- Users need to secure their auth setup
- Prevent brute force attacks
- Harden a Better Auth deployment
Example prompts
- “/better-auth-security-best-practices”
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.
- options.secret in your config
- BETTER_AUTH_SECRET environment variable
- AUTH_SECRET environment variable
What it can do on your machine
Read from SKILL.md and the folder at commit 9c163cf. 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_SECRETAUTH_SECRET
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Better Auth Security Best Practices loads about 2.7k tokens when it runs. Until then it costs about 90 tokens; SKILL.md has 453 words of instructions outside code blocks.
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 453 words (~2,651 tokens).
“Better Auth looks for secrets in this order:”
- name
- better-auth-security-best-practices
