Join this project's Brigade team from inside the session: this skill, given a path, runs `brigade team join --secret-file <path>` on the secret file the administrator sent, and the skill with no path re-consents a second checkout of a team this machine already holds. Use when the user asks to join and names the path of the secret file they saved — never with a path you chose or a file you wrote.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Join the team

`$ARGUMENTS` is the path of the secret file the user saved, or empty: typed by them when they invoked this skill, or
passed by you when they asked in words and you loaded this skill — the path exactly as they wrote it, or nothing
if they named none. The path is always **theirs**: never one you chose, guessed or wrote.

1. If `$ARGUMENTS` is non-empty, run exactly `brigade team join --secret-file "<that path>"` — the path quoted, one
   shell call. If it is empty, run exactly `brigade team join`. `brigade` here is the command the `Brigade:` line
   of this session named: the bare word when it is on your PATH, else the bootstrap's path that line gave (the
   `not joined` line names it in its `run …` clause). Nothing else: never read the file, never print or ask for
   its contents, never choose or guess a path, never retry with a different one.
2. Relay the command's output as it is. On success it names the team and says when this session attaches — at the
   next prompt, or, for a session already attached to another team, in a new session; repeat that to the
…

How to install

The exact contents, by fingerprint
mdr add appshapes/brigade/join@sha256:550e7a562b661df0

The line at the top of this page pins the label git:20261017.060f486, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
