Archcore Send

End-to-end-encrypted context handoff for AI coding sessions.

This server is a zero-knowledge ciphertext rendezvous. It stores only encrypted parts and never sees plaintext or the decryption key — the key lives in the link fragment and is parsed locally by the client.

Use it

Install the send skill, then point it at this server:

export SEND_SERVER_URL=https://v864364.hosted-by-vdsina.com
# package the current session and get a one-time link
/send
# load a link someone shared with you
/send --load <url>

Check your environment first with /send --doctor (needs age installed).

Links are one-time and short-lived. Treat the full link (with #agekey=…) like a secret — anyone with it can decrypt.
