Good to know

One player: no multiplayer, dice or combat.
Secrets are kept out of the player's views, not locked away: it's your own pebble.
Your AI narrates and the pebble keeps the record. Time between chats never moves the story.

Say what you want

What do you want to make?

Run a mystery adventure with me that I play in chat. Before we start, agree a premise, my character, a tone and how freely you may invent the story. Fix the mystery's solution and its clues before play, so the answer can't move to beat my theory. Keep the characters, places and items; lore that's open or secret; the state of the story: where I am, who holds each item, which clues I've found, how much people trust me, and which threads are open; and every turn I take, with what it changed.

Views: continue (a short recap, the scene and what's at stake), what I'm carrying, people I know, clues I've found, open threads, and a journal of my turns. Keep separate author views for secrets and the full state, and leave secrets out of everything I see as the player.

Rules: a turn and everything it changes save together or not at all. Turns are numbered in order, and two turns can't both follow the same one. Every item has exactly one holder: I can take only what's here and give only what I hold. A clue I've found stays found. Saved turns can't be edited or deleted; a mistake gets a correction turn with a reason. If a reply is lost, retrying the same turn returns the same result instead of playing it twice. Once the game ends, no more turns.

Write these as tests first. Inside the story, invent freely within what we agreed; ask me about anything outside it.

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.
