varnish AGENTS.md

varnish AGENTS.md is an instructions file for Codex, OpenCode from sous-chefs/varnish. It costs 886 tokens per session, scanned A, original, Apache-2.0.

Project guidance for the Varnish cookbook, a set of Chef files used to install and configure software automatically. It covers dependency setup, package sources for Debian/Ubuntu and RHEL-based systems, and platform details.

In plain words
What is it for?
Use it when changing Chef recipes, dependencies, package installation, or platform-specific configuration for Varnish.
Why use it?
It gives coding agents the repository's expected setup and helps avoid using package repositories or installation steps that do not work on a target operating system.

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

varnish 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.

Agent Guidance

This cookbook uses Policyfile.rb for dependency resolution. Run chef install Policyfile.rb after changing cookbook dependencies or test cookbook recipes, and keep Kitchen suites mapped to Policyfile named run lists.

Package Availability

APT (Debian/Ubuntu)

The Varnish Cache project hosts official community packages on Packagecloud and recommends manual repository setup rather than the Packagecloud installer scripts.

  • Ubuntu 20.04, 22.04, and 24.04 are documented by Varnish Software for Varnish Cache 6.0 LTS packages.
  • Debian and Ubuntu distro packages are available through the native package manager, but distro versions may differ from Varnish Cache LTS.
  • Packagecloud repository URLs use the pattern https://packagecloud.io/varnishcache/varnish<major_without_dot>/<platform>/.
  • During local Dokken verification on May 7, 2026, https://packagecloud.io/varnishcache/varnish60/ubuntu/ noble returned 404 for the Ubuntu 24.04 arm64 container, so the required default suite uses distro packages.

DNF/YUM (RHEL family)

The official Varnish documentation describes Packagecloud RPM repositories for Enterprise Linux. Varnish Cache 6.x package documentation explicitly covers EL 7 and EL 8. EL 9 compatible platforms may have distro packages, but this cookbook only treats Packagecloud availability as source-verified where upstream documents it.

  • RHEL-family platforms need the stock varnish DNF module disabled on EL 8 and newer before installing Packagecloud packages.
  • EPEL is still included for dependency compatibility on RHEL-family systems.
  • Packagecloud repository URLs use the pattern https://packagecloud.io/varnishcache/varnish<major_without_dot>/el/<major>/$basearch.

Zypper (SUSE)

No source-verified community Packagecloud support for openSUSE Leap was found for this cookbook migration, so openSUSE is not listed in metadata.rb or Kitchen.

Architecture Limitations

Packagecloud repository paths are architecture-aware for RPMs through $basearch. The Varnish documentation consulted does not provide a complete per-release architecture matrix for community DEB/RPM repositories, so the cookbook does not claim architecture-specific support beyond what the upstream repositories publish.

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.
