In plain words
What is it for?
Adding and reviewing tools for arkade get, system packages for arkade system install, binaries inside OCI container images, and Kubernetes charts or manifests.
Why use it?
They reduce guesswork when changing arkade and help prevent adding a tool through the wrong installation path.

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

arkade AGENTS.md scanned grade A with 1 finding 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.

AGENTS.md - Guide for AI Agents Contributing new downloads/apps/CLIs to Arkade

This document provides guidance for AI agents working on arkade, specifically for reviewing and adding new CLI tools to the arkade get command.

For system-level packages (usually Linux-only), see the arkade system install - usually for tools like Node.js, Go, Prometheus. Sometimes uses Go templates for tool definitions, often just uses its own code in the command. For binaries distributed via OCI images, see arkade oci install.

Types of Arkade Commands

Arkade provides several types of installers:

  • arkade get - CLI tools usually to be placed at /usr/local/bin/ or $HOME/.arkade/bin/. These are standalone binaries that can be downloaded and executed directly.

  • arkade system install - Linux-only system-level tools like Node.js, Go, Prometheus. These require additional installation steps or system configuration.

  • arkade oci install - Fetches binaries out of OCI images. Ideal for projects that use private repositories like slicer/actuated/k3sup-pro. Tools in the arkade get catalog may also declare an OCIImage field (see below), which makes them installable through arkade get as well.

  • arkade install - Kubernetes Helm charts or manifests for add-ons like OpenFaaS CE, Istio, PostgreSQL. These deploy software to Kubernetes clusters.

This guide focuses on arkade get - adding CLI tools that provide static binaries for download.

1. How to Add a New CLI (Tool) to Arkade

What Can Be Added

Only tools with static binaries can be added to arkade. The tool must provide pre-compiled binaries for download.

Cannot be added:

  • Python-based tools (e.g., aws-cli, azure-cli) - require Python runtime
  • Node.js-based tools without static binaries - require Node.js runtime
  • Tools that require installation scripts or package managers
  • Tools that need runtime dependencies beyond the binary itself

Prerequisites

  1. Fork and create a branch: git checkout -b add-TOOL_NAME

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.
