crew
the crew
agentmash crew is twenty-two Claude Code agents, a planner, a backend engineer, a reviewer and the rest, with Mash conducting. A team is some of them under a name you choose, committed into the repository:
npx agentmash team add "agentmash crew" --agents pipe,flex,probewrites an agent file under .claude/agents/ for each member and for Mash, who is on every
team, the crew's shared skills, one skill for the team, one guard hook in
.claude/settings.json and .claude/agentmash-crew/teams.json, which records what it wrote.
Commit them, start a new Claude Code session at the root of the repository, and say
agentmash crew, <your task>. The command needs the agentmash CLI 0.4.0 or later, which
carries the crew at the version crew/crew.lock.json records, so a team is the same files
whichever day it was installed.
The site has three ways in. /agents lists the crew and /agents/<name> shows one of them;
/teams/new builds a team, then copies the command, opens a pull request with it (sign in
with GitHub and pick a repository), or opens Claude Code with a prompt that runs it. /agents
shows an example of the command where it says how a team is set up. A server closed to new
teams (AGENTMASH_CLOSED) changes nothing on these pages; it is the server that refuses: only
someone the allowlist lets sign in can open the pull request.
The pull request holds exactly what the command writes, because both run the crew's own planner at one
commit, the copy vendored in crew/: the server for the pull request, the CLI package for the
command. server/test/crew.test.ts compares the two file for file. Like the command, it refuses to overwrite a file the crew did
not write. It only ever adds files, and it never creates a room, so on a server closed to new
teams it works for anyone the allowlist lets sign in. It opens one team's pull request at a
time (every one writes teams.json, so a second would conflict with the first), and it takes
repositories with up to 50 teams; past that, the command does it in a checkout.
crew/ is written by tools/sync-crew.mjs from a clean checkout of the crew repository at a
tag, never by hand; crew/README.md says how to update it.
