AGENTS.md

noerd AGENTS.md is an instructions file for Codex, OpenCode from noerd-dev/noerd. It costs 2,172 tokens per session, scanned A, original, MIT.

Repository instructions for AI coding agents working on noerd. They describe the project, its workflow, tests, and code style.

In plain words
What is it for?
Use them when contributing code, running tests, or following noerd’s development conventions.
Why use it?
They help an agent understand how this codebase is organized and how changes should be checked before submission.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is noerd-dev/noerd's own configuration. It tells Codex and OpenCode how to work on noerd 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 noerd 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

noerd 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 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.

AGENTS.md — contributing to noerd/noerd

This file is for humans and AI agents working inside this repository (the noerd core package, noerd/noerd). The rules for building with noerd — lists, details, pages, modals, modules, tests in a host project — are shipped as a Laravel Boost guideline in resources/boost/guidelines/core.blade.php (plus the Boost skills in resources/boost/skills/) and are NOT repeated here. Read that guideline first; it applies to code in this repository as well.

What this repository is

  • A Laravel package: YAML-driven list/detail/page components (NoerdList, NoerdDetail, NoerdPage traits), the modal system, themes, navigation, tenant apps, install/update commands.
  • It is consumed either from Packagist (vendor/noerd/noerd) or as a git submodule at app-modules/noerd with a Composer path repository (symlinked) — the host project then contains the package source directly.
  • docs/ is the single source of the public documentation (https://noerd.dev). The repository noerd-dev/docs is an auto-synced mirror (.github/workflows/sync-docs.yml) — never edit the mirror, it is overwritten on every push to main.
  • Released under the MIT license (LICENSE, Copyright (c) 2026 Johannes Brock). Keep the file in the Packagist archive — .gitattributes export-ignores development-only paths, never LICENSE.
  • Every test lives in a subdirectory of tests/ (Feature, Components, Unit, Commands, Helpers, Middleware, Traits); the root of tests/ holds only the shipped test API (TestCase.php, HelperLoader.php, helpers.php, Pest.php).

Workflow

  • Never commit or push directly to main — the branch is protected on GitHub, a direct push is rejected. Create a feature branch, push it and open a GitHub pull request against main; squash-merge once the required checks are green.
  • Release: tagging a version requires the composer.json "version" field to equal the tag in the tagged commit. The bump is a PR like any other (Bump version to vX.Y.Z); tag the merged commit, then publish the GitHub release with ### Added / Fixed / Changed / Docs sections.
  • Composer constraints: when a framework constraint is tightened or loosened, check every package of the ecosystem that depends on it (noerd/modal, the modules) — Composer silently falls back to the newest tag that still satisfies the host, so an open range like ^0.3 keeps resolving to an old version without any error. Raise the minimum along with the change.
  • A pushed tag is immutable — never move it. Packagist indexes a version once and keeps the commit it saw first, so re-pointing an existing tag keeps shipping the old code while the repository looks correct. Consumers see no reason to update, because the version number did not change. Anything that has to reach users goes into the next patch release instead. This is not hypothetical: v0.11.0 was moved to a later commit after it had been published, Packagist kept serving the commit from five days earlier, and the released v0.11.0 was therefore older than v0.10.13 — ^0.11.0 resolved to less code than ^0.10.
  • Commit messages: one concise sentence describing the change. No generated-by footers, no co-author lines.
  • Do not change dependencies (composer.json require) without explicit agreement.

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.
