skills-agents-ai-coding: Instructions file for Codex

AGENTS.md

skills-agents-ai-coding AGENTS.md is an instructions file for Codex, OpenCode from mir-am/skills-agents-ai-coding. It costs 1,693 tokens per session, scanned A, original, MIT.

A project guide for a collection of reusable instructions and specialized AI assistants for coding command-line tools. It explains the repository layout and how skills and agents are organized.

In plain words
What is it for?
Use it when working on skills, agent definitions, repository structure, or the synchronization script that installs them for supported coding tools.
Why use it?
It gives an AI coding assistant the context needed to find the right files and follow the project's conventions. This reduces guesswork when adding or updating instructions.

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

skills-agents-ai-coding 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 28d 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.

Project Overview

This is Mir's Agents & Skills for AI Coding Assistants, a collection of reusable Agent Skills and agents for CLI coding assistants, hosted in the opencode-skills repository. Skills are markdown-based instruction sets that teach AI agents specific workflows using the open Agent Skills format. Agents are markdown-based definitions that create specialized AI assistants with custom prompts, tools, and permissions.

Skill Anatomy

Each skill is a directory under skills/ containing a SKILL.md file.

  1. YAML frontmatter with metadata in the repository source format:

    ---
    name: <skill-name>
    description: <one-line description>
    license: MIT
    metadata:
      audience: developers
      workflow: <category>
      category: <category>
    ---
    
  2. Markdown body with structured sections:

    • ## What I do - Bullet list of capabilities
    • ## When to use me - Trigger conditions
    • Workflow sections with step-by-step instructions
    • Code blocks with exact commands to run
    • Edge cases and error handling

Agent Anatomy

Each agent is a single .md file in the agents/ directory. The filename (minus .md) becomes the agent name.

  1. YAML frontmatter with configuration:
    ---
    description: <one-line description>
    mode: subagent          # or "primary"
    model: <provider/model-id>
    temperature: <0.0-1.0>
    tools:
      write: true/false
      edit: true/false
      bash: true/false
      read: true/false
      glob: true/false
      grep: true/false

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.
