## Product

- One library per person. Named shelves. Markdown cards (Identity / Details / Tags / Body).
- Unlimited Markdown on every plan. Attachments and extra named shelves are metered.
- One default agent key (every shelf). Uncapped extra keys with grants.
- Lite / Education: 1 named shelf (0 extra). Pro: 10 extra shelves. Ultra: 50 extra shelves. Lifetime 1: 20 named shelves. Lifetime 2: 100 named shelves. Operator uncapped.
- Owner login uniquely owns card delete, billing, rotating the default key, and deleting the account (Billing). A leaked default Bearer cannot rotate itself or delete the account.
- Agents use host MCP. Never curl librarian HTTP. Never paste keys in chat.
- Device connect: the agent sends a /connect?device= link; the human enters the key there.

## Install

Same GitHub repo (`zeyu-j/centricmem-skill`): SKILL.md plus Agent Plugins 1.0.

Paste one line to the agent:

```
Install CentricMem from zeyu-j/centricmem-skill. If CLI is blocked, send https://centricmem.com/login?signup=1 — never paste keys.
```

After connect, if the library is empty the agent offers once to file notes you already have as cards. Capture stays in the agent. They may skip. The agent says once which key this chat is using. Extra grants: tick shelves on Keys.

Terminal in this project:

```
npx --yes skills add zeyu-j/centricmem-skill --skill centricmem-agent -y
```
