agent-skills: Instructions file for Codex

AGENTS.md

agent-skills AGENTS.md is an instructions file for Codex, OpenCode from AsyrafHussin/agent-skills. It costs 533 tokens per session, scanned A, original, MIT.

Instructions for a repository of reusable guidance for AI coding agents working with React, Laravel, PHP, databases, APIs, testing, security, and related tools. Each skill is a focused set of development rules.

In plain words
What is it for?
Use them when building React or Laravel features, designing APIs, improving database queries, writing tests, applying security practices, or managing Git work.
Why use it?
They show which guidance is available and help an agent choose practices suited to the project's technology stack.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is AsyrafHussin/agent-skills's own configuration. It tells Codex and OpenCode how to work on agent-skills itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-skills configures →

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

agent-skills AGENTS.md 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 9d 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.

Usage

Skills in skills/ directory follow the Agent Skills format. Each skill has:

  • SKILL.md - Main instructions with YAML frontmatter
  • rules/ - Detailed rules (loaded on demand)

Contributing

When adding new rules:

  1. Follow the existing rule template in rules/_template.md
  2. Include incorrect and correct code examples
  3. Explain the "why" not just the "what"
  4. Add appropriate priority level

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.
