Use a project from another machine

npx brynth init creates a new project. To use an existing one from a second machine, bring a key, not the admin credentials.

1. Create a key on the first machine

--platform must name the client that will use the key: the skill's session_hello sends that client's name, and a key fixed to another platform keeps its identity and returns an IDENTITY_CONFLICT warning, so the ledger would record the wrong client. For Claude Code:

npx brynth key create --scopes inbox:read,inbox:write,send,disk,approvals,ledger:read --platform claude-code --label laptop-2

For Codex:

npx brynth key create --scopes inbox:read,inbox:write,send,disk,approvals,ledger:read --platform codex --label laptop-2

The token is printed once. Move it with a password manager, not by chat or email. Add admin to the scopes only if the agent there must add sources or keys. --platform alone sets the agent name too (lower-cased); --agent needs --platform. Without either, the first session_hello sets the key's identity. Create one key per client: two clients on the same machine need two keys.

2. Connect the client on the second machine

From the project folder, with the key created for that client:

BRYNTH_KEY=brk_live_… npx brynth connect claude-code
npx brynth skill install --client claude-code

For Codex, connect codex and skill install --client codex, with the Codex key.

With BRYNTH_KEY set, connect creates no key and writes nothing to credentials.json: it writes the key of the environment into the client configuration. It does not install the skill, hence the second command; without --client, a machine with no saved project gets the skill for both clients.

BRYNTH_KEY=brk_live_… npx brynth status shows the project with that key; sections the key cannot read say which scope they need.

3. Revoke when done

On the first machine, npx brynth status --json lists the active keys with their ids. Revoke one with DELETE /v1/keys/{id} and the admin key (see REST).

Signing in to an existing project from the CLI, without a key, is not available yet.
