What it does
Security Audit is an agent skill from theopenco/llmgateway. Security best practices, vulnerability review, and full security audits for LLM Gateway. Use when writing security-sensitive code (auth, sessions, API keys, provider keys, billing, webhooks, user-supplied URLs, admin routes, CORS, rendering user content), when asked for a security review, security report, vulnerability research, pen test, or security audit, and for the monthly audit routine that fixes confirmed findings in a PR.
Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 27 other files, including reference files (for example `AI-AND-LLM.md`, `ATTACK-CLASSES.md` and `AUDIT-WORKFLOW.md`).
It sits in Security, covering Security review. It works with JavaScript, Hono and TypeScript. The repository describes itself as: Route, manage, and analyze your LLM requests across multiple providers with a unified API interface.
When your agent uses it
- Writing security-sensitive code (auth
- User-supplied URLs
- Rendering user content)
- Asked for a security review
Example prompts
- “/security-audit”
What it can do on your machine
Read from SKILL.md and the folder at commit ba1f176. 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:
nodepnpm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pnpm, which can reach the network depending on how they are called.
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 Audit loads about 1.8k tokens when it runs, and up to ~45k if it reads all its reference files. Until then it costs about 112 tokens; SKILL.md has 494 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 494 words (~1,767 tokens).
“Merged from OpenAI's security-best-practices (secure defaults per framework) and Cloudflare's security-audit (evidence-first audit workflow). Licenses: LICENSE-openai (Apache-2.0, files under references/) and LICENSE-cloudflare (MIT, the upper-case companion files, validators, and report-schema.json).”
