home-ops: Instructions file for Codex

AGENTS.md

home-ops AGENTS.md is an instructions file for Codex, OpenCode from gavinmcfall/home-ops. It costs 2,973 tokens per session, scanned A, original, MIT.

Repository instructions for the home-ops project, whose infrastructure is managed through GitOps: configuration stored in Git is used to keep the running system aligned with the repository.

In plain words
What is it for?
Use them when working on home-ops infrastructure, especially its architecture, workflows, conventions, and GitOps reconciliation behavior.
Why use it?
They point coding agents to the central documentation and highlight rules that must remain true, such as automatic correction of manual cluster changes.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions CLAUDE.md; mentions Claude Code; mentions Codex.

This is gavinmcfall/home-ops's own configuration. It tells Codex and OpenCode how to work on home-ops 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 home-ops configures β†’

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /home/gavin/home-ops/.

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

home-ops AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories β€” prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency β€” measured 19d 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.

AI Assistant Configuration

This repository uses multiple AI coding assistants with shared context from a centralized documentation hub.

πŸ“š Documentation Location

All AI assistant context is centralized in docs/ai-context/:

  • README.md - Overview and navigation
  • ARCHITECTURE.md - GitOps architecture, key decisions, and constraints
  • DOMAIN.md - Business rules, entity relationships, and invariants
  • WORKFLOWS.md - Operational workflows and procedures
  • TOOLS.md - Tool usage patterns and discovery commands
  • CONVENTIONS.md - Coding standards and project guidelines

This centralized approach provides:

  • βœ… Single source of truth for all AI tools
  • βœ… No duplication across tool-specific directories
  • βœ… Easy updates - change once, all tools benefit
  • βœ… Version controlled and team-friendly
  • βœ… Future-proof for new AI assistants

πŸ“– Read First

  1. docs/ai-context/Ethos.md - Documentation philosophy
  2. docs/ai-context/ARCHITECTURE.md - System architecture
  3. docs/ai-context/CONVENTIONS.md - Coding standards

πŸ“• Ebooks & audiobooks live in another repo

This repo holds only the cluster manifests for the reading stack (Bindery, CWA/Calibre, Audiobookshelf, BookOrbit, Kavita, and friends). Everything else for that domain β€” the pipeline, acquisition, metadata, the genre tree, imports, tooling, decisions and session journal β€” lives in the nerdz-reading repo.

Before doing reading-stack work beyond a manifest change, read there:

  • docs/README.md β€” the index: which docs are canonical and which are superseded
  • docs/ebook-curation-pipeline.md β€” the pipeline (Β§10 field-proven corrections, Β§11 Bindery, Β§12 genre taxonomy)
  • .repoql/concepts/ β€” the invariants as capsules

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.
