Say what you want

What do you want to make?

Help me keep a personal cabinet of curiosities. Keep entries (objects, recipes, stories, photos and places) with a description and, if I know them, when and where I got them, as an exact date or a rough label like "summer, around 1998"; accounts of each entry (provenance, memories, legends or interpretations) with a source and how sure it is; links to pictures or documents, with credit; tags; connections between entries, with why they're connected; and exhibitions of ordered entries with captions.

Views: the cabinet, recently added, entries by theme, stories and provenance, connected entries, draft and frozen exhibitions, entries with uncertain provenance, and the archive.

Rules: an entry needs a description, and an exact date must be a real one; never turn a rough label into a date. Conflicting memories sit side by side. Correct an account by adding a new one that replaces it, never by editing it, and corrections can't loop. An entry can't connect to itself, or to the same entry twice for the same reason. Freezing an exhibition needs at least one entry and keeps a copy of its captions, chosen accounts and links, so later edits don't change it. An entry that's been in an exhibition is archived, not deleted.

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.
