agent-skills AGENTS.md

agent-skills AGENTS.md is an instructions file for Codex, OpenCode from dmythro/agent-skills. It costs 1,491 tokens per session, scanned A, original, MIT.

Contributor instructions for a documentation-only repository of skills for AI coding agents. It describes the Markdown folder structure and the manual review needed because the repository has no application build or test system.

In plain words
What is it for?
Use it when adding or editing skill documents, reference files, links, or permission lists in that repository.
Why use it?
It helps contributors follow the required document format and avoid looking for automated tests or build commands that do not exist.

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 5d 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.

Repository Overview

This is a documentation-only repository containing agent skills -- structured Markdown reference documents designed to be installed into AI coding agents (OpenCode, Claude Code, Copilot, etc.) via the skills.sh ecosystem. There is no application code, no build system, no dependencies, and no tests.

Structure

skills/
  <skill-name>/
    SKILL.md              # Main entry point (has YAML frontmatter)
    references/
      <topic>.md          # Deep-dive reference documents
      allowlist.md        # Tool permission patterns (optional)

Current skills: bun-api, bun-cli, git-commit, git-pr, git-ci, git-project, coderabbit.

Build / Lint / Test Commands

There are none. This repository contains only Markdown files. No package.json, no CI/CD, no linter configuration, no test runner.

To validate changes, manually review Markdown rendering. If adding links, verify they point to valid targets.

Content Style Guidelines

SKILL.md Files (Main Entry Points)

Every skill's SKILL.md must include YAML frontmatter:

---
name: skill-name
description: >-
  What the skill covers, when to use it, and when not to use it.
  No trailing period. Use YAML folded scalar (>-) for multi-line
---
  • name: kebab-case, matches the directory name
  • description: concise, plain text, no trailing period. Use YAML >- (folded scalar) for multi-line. Include trigger guidance (when to use / not use) since skills.sh uses this field for auto-loading decisions

Document Structure

  1. H1 heading immediately after frontmatter -- matches the skill's subject
  2. Opening paragraph -- bold, concise, establishes context and scope
  3. "When to Use" section -- bullet list of triggering scenarios
  4. "Critical Rule" or "Critical Rules" section -- bold, imperative, must-follow constraints
  5. Major topic sections (H2) covering the skill's API/CLI surface
  6. Key Gotchas / Best Practices -- a numbered list at the end; use either name (most skills use ## Key Gotchas)
  7. References -- blockquote pointers to references/*.md files

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.
