What it does
Security Practices is an agent skill from eser/stack. Security rules for eserstack in TypeScript and Go: secrets, output hygiene, input validation, authorization, injection, SSRF, error sanitization, httpfx hardening, tokens, passwords, cookies, crypto, untrusted files and archives, LLM trust. Use when handling secrets, input, auth, sessions, cookies, crypto, uploads, subprocesses, outbound URLs, prompts, production config or a security review.
Its SKILL.md is about 600 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `evals/triggers.json`, `references/crypto-and-files.md` and `references/http-and-auth.md`).
It sits in Security, covering Web application vulnerabilities, Security review and Authorization and RBAC. It works with TypeScript. The repository describes itself as: The Portability Solution for Your Code! 🚀 Powered By Deno and JavaScript.
When your agent uses it
- Handling secrets
- Production config
- A security review
Example prompts
- “/security-practices”
What it can do on your machine
Read from SKILL.md and the folder at commit 64939e6. 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
No scripts in the folder and no shell commands in SKILL.md.
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 no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Security Practices loads about 598 tokens when it runs, and up to ~7.2k if it reads all its reference files. Until then it costs about 103 tokens; SKILL.md has 199 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
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 199 words (~598 tokens).
“Security rules that apply to every package and service in the repository.”
