What it does when it runs

Register this agent and terminal with Reach for cards, calls and wake-ups. Use when asked to join, connect, or become reachable, or when a manually opened agent lacks `SNO_EXECUTOR_ADDR`.

join-talk

Needs: tmux (or the optional Orca app) as the terminal, jq, flock, and the sno CLI with its Reach runtime. Reach is the messaging layer between agents (see the reach skill): a seat is one registered terminal with an address, a card is a stored message, and a ring is the wake-up that asks the agent to read its inbox. SNO_EXECUTOR_ADDR is the environment variable holding that address for agents opened through Reach; a manually opened agent has none, which is what this skill fixes.

Run this once, from your own shell tool, in the repository you are working on. The script ships beside this file:

bash scripts/join-talk.sh

(Give the full path of this skill's scripts/join-talk.sh under whichever skills root your harness loaded it from.)

It prints one line, joined <address>. Tell the person that exact address, then go back to what you were doing. Rerunning it from the same terminal changes nothing. The seat is registered wherever agents on this machine are addressed, so cards, rings and a handoff find this terminal; sno reach call works for a tmux terminal, not for an Orca one.

Options, only when the person names them: join-talk.sh review.example-repo@host1 picks the address; --name Fjord picks the display name. Otherwise the address is hand.<repo>@<host> and the name is the repository name.

After joining

  • A card for you arrives with a ring in this terminal. Read it with sno reach inbox --as <address>; reading does not accept it.
  • Answer with sno reach reply --as <address> --card <card> --state <state>, body on stdin. The installed Reach guide (sno reach --help) shows the card shape and states.

When it refuses

  • no terminal to be reached at — this shell is under neither tmux nor the optional Orca app; nobody can ring it. Tell the person; do not retry.
  • sno is missing — the machine lacks the Reach install (sno setup installs it). Tell the person; do not retry.
  • jq is missing or flock is missing — install it (flock comes from util-linux), then run it again.
  • ORCA_TERMINAL_HANDLE is empty — an Orca shell without a terminal handle; Reach cannot address it. Tell the person; do not retry.

Files bundled with it

These load only when the skill asks for them, so they cost nothing until it runs.
