SECURITY

A security policy and reporting guide for a project containing agent skill instructions and interface patterns.

In plain words
What is it for?
Use it to report security problems through GitHub's private security advisory process and to guide contributors away from secrets, unsafe instructions, and executable code in skill files.
Why use it?
It explains how to handle suspected vulnerabilities privately instead of exposing them in a public GitHub issue, a public discussion page for code projects.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Per session 0 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.
When invoked 230 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 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 yesterday.

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 Policy

Reporting a Vulnerability

If you discover a security vulnerability in this project, please report it responsibly. Do NOT open a public GitHub issue for security vulnerabilities. Open a private security advisory via GitHub Security tab.

Response Timeline

  • Acknowledgment: within 48 hours
  • Initial assessment: within 7 days
  • Fix or mitigation: depends on severity

Scope

This repository contains Markdown-based skill definitions and UI component patterns.

Skill files (.md)

  • Non-executable prompt definitions
  • No API keys, secrets, or credentials should be stored in skill files
  • Skills are read by AI agents — never include instructions that could be exploited

Component patterns

  • CSS-only patterns with no executable JavaScript
  • No external dependencies or CDN links
  • Safe to use in any project

Best Practices for Contributors

  • Never commit API keys, tokens, or credentials
  • Never add executable code inside skill Markdown files
  • Never include instructions that could be used for prompt injection
  • Report suspicious skill definitions that attempt to manipulate agent behavior
  • Keep skills focused on their stated purpose
Changes

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 is a skill published in the GitHub repository subhansh-dev/agent-maxxing (2 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 230 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 2026-08-31.
