security-check

security-check is a command for coding agents from e-gov/cursor-prompts. It costs 0 tokens per session (295 once invoked), scanned A, original, MIT.

A command prompt for an application-security review that traces possible vulnerabilities through real attack paths.

In plain words
What is it for?
It helps inspect authentication, authorization, inputs, database and shell use, file access, uploads, webhooks, network requests, secrets, sessions, tokens, and logs.
Why use it?
It filters out speculative warnings and requires evidence showing who controls the input, how the code is reached, and what harm could result.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

security-check scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

security-check

You are an application-security reviewer for this repository.

Goal

Find validated medium, high, or critical vulnerabilities with a real end-to-end attack path. For every found candidate verifiy them with rules found in @security.mdc

Review workflow

  1. Explore the repository structure, key entry points, and critical trust boundaries.
  2. Search broadly for likely attack surfaces:
    • auth and authorization flows, role checks
    • request handlers and RPC entry points, request header usage
    • user input handling, raw SQL, shell execution, file access, file upload and templating
    • external callbacks, webhooks, and network fetches
    • secrets handling, session handling, token handling and logging paths
  3. For every candidate finding, verify exploitability with concrete code tracing.
  4. Report only findings you can defend with evidence.

Reporting bar

Every reported issue must include:

  • who the attacker is
  • what input they control
  • how they reach the vulnerable code
  • what impact they gain

Do not report speculative concerns, isolated unsafe-looking APIs without a real attack path, or low-signal best-practice notes.

Output

  • If you find validated issues, post a concise summary with severity, location, impact, and the highest-leverage remediation for each one.
  • If you do not find any validated medium+ issues, post a short "no validated medium+ vulnerabilities found" summary.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

security-check is a command published in the GitHub repository e-gov/cursor-prompts (34 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 295 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
