golang-agent-skills: Instructions file for Codex

AGENTS.md

golang-agent-skills AGENTS.md is an instructions file for Codex, OpenCode from daibang123a/golang-agent-skills. It costs 755 tokens per session, scanned A, original, MIT.

Repository instructions for creating and maintaining AGENTS.md files and coding-agent skills in a Go project.

In plain words
What is it for?
They cover the repository layout, kebab-case naming, required SKILL.md files, optional scripts and references, and skill-file formatting.
Why use it?
They give contributors a shared structure and naming rules, so agents and developers can find project guidance consistently.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md.

This is daibang123a/golang-agent-skills's own configuration. It tells Codex and OpenCode how to work on golang-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 golang-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

golang-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 10d 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.

AGENTS.md

This file provides guidance to AI coding agents (Claude Code, Cursor, Copilot, etc.) when working with code in this repository.

Repository Overview

A collection of skills for AI coding agents working with Go (Golang). Skills are packaged instructions and scripts that extend agent capabilities.

Project Structure

skills/
  {skill-name}/               # kebab-case directory name
    SKILL.md                   # Required: skill definition
    scripts/                   # Optional: executable scripts
      {script-name}.sh         # Bash scripts (preferred)
    references/                # Optional: detailed reference docs
      {topic}.md               # Markdown reference files
    assets/                    # Optional: templates, examples

Naming Conventions

  • Skill directory: kebab-case (e.g., go-best-practices, docker-deploy)
  • SKILL.md: Always uppercase, always this exact filename
  • Scripts: kebab-case.sh (e.g., lint-check.sh, generate-dockerfile.sh)
  • References: kebab-case.md (e.g., allocation-guide.md, channel-patterns.md)

SKILL.md Format

---
name: {skill-name}
description: >
  {One sentence describing when to use this skill.
  Include trigger phrases like "Review my Go code",
  "Optimize performance", etc.}
---

# {Skill Title}

{Brief description of what the skill does.}

## How It Works
{N-step explanation of the skill workflow}

## Rules
{Categorized rules, prioritized by impact}

Guidelines for Modifications

Adding a New Skill

  1. Create a new directory under skills/ with a kebab-case name
  2. Add a SKILL.md with valid YAML frontmatter (name and description required)
  3. Keep SKILL.md under 500 lines — put detailed reference material in references/
  4. Write specific descriptions — helps the agent know exactly when to activate
  5. Use progressive disclosure — reference supporting files read only when needed
  6. Add scripts for repeatable automation tasks

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.
