shopmon: Instructions file for Codex

AGENTS.md

shopmon AGENTS.md is an instructions file for Codex, OpenCode from FriendsOfShopware/shopmon. It costs 1,961 tokens per session, scanned A, original, MIT.

A project-specific AGENTS.md instruction file for the Shopmon application. It documents the project's architecture, technologies, directory layout, coding conventions, and error-handling guidance.

In plain words
What is it for?
Use it as a guide when modifying Shopmon's Go API, Vue and TypeScript frontend, PostgreSQL database, queues, storage, or observability code.
Why use it?
It gives coding agents and contributors the local rules they need instead of making them infer the structure and conventions from the repository. This helps keep changes aligned with the existing project.

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

This is FriendsOfShopware/shopmon's own configuration. It tells Codex and OpenCode how to work on shopmon 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 shopmon 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

shopmon 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.

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.
