Shintenshin — mind transfer awaits you

A forbidden jutsu, sealed in cipher, carries one mind's memory across the wire to another vessel.

Install the plugin:

claude plugin marketplace add seal-7/shintenshin
claude plugin install shintenshin@shintenshin

Send your current conversation, from within Claude Code:
```
/shintenshin:send
```
Prints a share link valid for 7 days. Anyone with the link can import the conversation — treat it like a password.
Receive a conversation someone shared with you, from the project folder where you want it to land:
```
/shintenshin:receive <PASTE FULL URL>
```
Every transfer is end-to-end encrypted (AES-256-GCM) — the decryption key lives only in the URL fragment and never reaches the server.
Blobs are deleted automatically after 7 days.
