appkit: Command for GitHub Copilot

.github/prompts/create-agentsmd.prompt.md

create-agentsmd is a command for GitHub Copilot from jenreh/appkit. It costs 11 tokens per session (1,656 once invoked), scanned A, original, MIT.

A command for generating an AGENTS.md file, a Markdown file that gives coding agents repository-specific context and instructions.

In plain words
What is it for?
It helps create a root or subproject instruction file covering agent-focused setup and repository guidance, including projects organised as monorepos.
Why use it?
It puts technical guidance in a predictable place so automated coding tools do not have to infer project conventions from scattered files.

Command for GitHub Copilot

Written for GitHub Copilot: a Copilot chat mode or prompt. Also seen: agent in frontmatter; mentions AGENTS.md; built for aider.

This is jenreh/appkit's own configuration. It tells GitHub Copilot how to work on appkit 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 appkit 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

create-agentsmd 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 1mo 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.

Create high‑quality AGENTS.md file

You are a code agent. Your task is to create a complete, accurate AGENTS.md at the root of this repository that follows the public guidance at https://agents.md/.

AGENTS.md is an open format designed to provide coding agents with the context and instructions they need to work effectively on a project.

What is AGENTS.md?

AGENTS.md is a Markdown file that serves as a "README for agents" - a dedicated, predictable place to provide context and instructions to help AI coding agents work on your project. It complements README.md by containing detailed technical context that coding agents need but might clutter a human-focused README.

Key Principles

  • Agent-focused: Contains detailed technical instructions for automated tools
  • Complements README.md: Doesn't replace human documentation but adds agent-specific context
  • Standardized location: Placed at repository root (or subproject roots for monorepos)
  • Open format: Uses standard Markdown with flexible structure
  • Ecosystem compatibility: Works across 20+ different AI coding tools and agents

File Structure and Content Guidelines

1. Required Setup

  • Create the file as AGENTS.md in the repository root
  • Use standard Markdown formatting
  • No required fields - flexible structure based on project needs

2. Essential Sections to Include

Project Overview
  • Brief description of what the project does
  • Architecture overview if complex
  • Key technologies and frameworks used
Setup Commands
  • Installation instructions
  • Environment setup steps
  • Dependency management commands
  • Database setup if applicable
Development Workflow
  • How to start development server
  • Build commands
  • Watch/hot-reload setup
  • Package manager specifics (npm, pnpm, yarn, etc.)
Testing Instructions
  • How to run tests (unit, integration, e2e)
  • Test file locations and naming conventions
  • Coverage requirements
  • Specific test patterns or frameworks used
  • How to run subset of tests or focus on specific areas

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.
