openstock AGENTS.md

Development instructions for OpenStock, a self-hosted system for managing inventory and stock levels. It documents the Nuxt and Vue application, its SQLite-based database, and Cloudflare deployment.

In plain words
What is it for?
Running the development server, building the app, generating or syncing database changes, exporting data, and deploying to Cloudflare Pages.
Why use it?
It records the commands and project structure needed to develop, update the database, build, and deploy the system.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

openstock 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 2d 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.

Code Style Guidelines

Imports

// 1. External packages first
import { eq, desc } from 'drizzle-orm';

// 2. Server schema imports using the ~ alias
import { products } from '~~/server/database/schema';
import type { Product, Category } from '~~/server/database/schema';

// Nuxt auto-imports (no explicit import needed): useDB, tables, defineEventHandler, ref, reactive, computed, useFetch

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.
