Say what you want

What do you want to make?

Help me track my inventory. Keep items with a SKU, a name and a unit; my locations; which items are kept at which location, each with a reorder point and a target quantity; and every stock movement: opening stock, receipts, issues, transfers between locations, and adjustments in or out.

Views: a few headline numbers, stock on hand by item and location, a reorder list of anything low or out with how much to order to reach the target, recent activity, and a bar chart of stock health.

Rules: quantities come from movements, never typed in. A movement's quantity is positive, and stock can't go below zero. Receipts go to a location, issues come from one, and a transfer moves between two different locations in one step. Adjustments need a reason. SKUs are unique, ignoring case. A target can't be below the reorder point, and low means at or below it. Movements can't be edited or deleted: correct one with an adjustment. An item's unit can't change once it has moved. Every item kept at a location shows, even at zero.

Write these as tests first. Ask me rather than invent names, amounts or dates.

Instructions for your AI

Use my pebblebase connector. If its tools are not available in this chat, stop and give me this link to add it in Claude: https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=pebblebase&connectorUrl=https%3A%2F%2Fmcp.pebblebase.dev%2Fmcp (or tell me to add https://mcp.pebblebase.dev/mcp as a custom connector under Customize → Connectors), then tell me to start a new chat and paste this prompt again. You cannot add the connector for me. Setup steps: https://pebblebase.dev/pebblebase/agent-guide.md. Never ask me to paste passwords, passkeys, or tokens. Look for an existing project before creating another. Save its records and usage instructions for future chats. Only confirm a save after a successful tool result.
