emacs AGENTS.md

emacs AGENTS.md is an instructions file for Codex, OpenCode from sous-chefs/emacs. It costs 795 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for an Emacs installation cookbook, including package choices, dependency management, and known platform limitations.

In plain words
What is it for?
Use them when changing Emacs installation recipes, package defaults, platform support, or the cookbook's dependency configuration.
Why use it?
They help coding agents preserve existing recipes and choose the correct system package for Debian-, Ubuntu-, Fedora-, and RHEL-family systems. They also prevent the project from returning to an unsupported dependency tool.

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

emacs 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 4d 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.

Cookbook Purpose

Provides the emacs_package resource for installing Emacs

Agent Findings

  • This cookbook is in an incremental modernization pass. Preserve existing public recipes and attributes unless a later full migration is explicitly selected.
  • Dependency management should use Policyfile.rb; do not reintroduce Berkshelf.

Known Limitations

Package Availability

GNU Emacs does not publish a separate vendor APT or RPM repository for this cookbook to manage. This cookbook installs from each platform's standard package repositories.

APT (Debian/Ubuntu)

  • Ubuntu 24.04 LTS publishes emacs, emacs-nox, and GUI variants from the emacs source package. The emacs-nox package is published for amd64, arm64, armhf, ppc64el, riscv64, and s390x.
  • Debian 12 ships emacs and emacs-nox in the main archive, with newer builds also available from bookworm-backports.
  • The cookbook default for Debian-family platforms is emacs-nox, which matches the terminal-first package name used by both Debian and Ubuntu.

DNF/YUM (RHEL family / Fedora)

  • Fedora publishes emacs plus emacs-nw, the terminal-focused subpackage used by this cookbook.
  • RHEL 9 compatible repositories publish emacs, emacs-common, and emacs-nox. Current EL9 package indexes show builds for at least x86_64 and aarch64.
  • This cookbook defaults to emacs on RHEL-family platforms because emacs is the stable package name across those repositories, while Fedora keeps a distinct emacs-nw package for terminal-only installs.

Arch Linux

  • Arch Linux publishes both emacs and emacs-nox in the extra repository.
  • Current package metadata is published for x86_64.

FreeBSD

  • FreeBSD publishes emacs packages through the ports tree, with flavors including emacs, emacs-nox, emacs-canna, and emacs-wayland.
  • Current package indexes show emacs and emacs-nox builds across multiple supported architectures, including aarch64 and amd64.
  • The legacy editors/emacs-nox11 path used by the old cookbook is obsolete under the current FreeBSD package flavor model.

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.
