Supervise multiple agent sessions on this machine. Roster, status, GO-board, GO-token protocol. Adopt or spawn workers.
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
# `/master-session` — Supervise Other Sessions One session is the **master**: it keeps the overview, asks workers for status, and relays the human's decisions. It never does the workers' jobs and never decides for the human. Needs Claude Code with cross-session messaging (`ListAgents`, `SendMessage`). Nothing here requires the AO daemon. ## Modes - **Adopt** — supervise sessions the human already started by hand. `ListAgents` is the source of truth; message them with `SendMessage`. - **Spawn** — start the workers yourself. AO is optional; without it: - Claude: `claude --bg --name <name> --permission-mode auto "<prompt>"`, or over ACP as below. - Codex / OpenCode / Claude over ACP: `aos-acp <codex|opencode|claude> --name <name> --cwd <worktree> --prompt "<task>" --go-wait 600 &` (one process per worker; run it in the background and read its log). Details: `docs/master-session-acp.md`. - agy: `aos-acp agy ...` runs the vendor's `agy --print` (no ACP server, so no per-tool GO requests; `--allow-default` maps to agy's modes, see `docs/delegation-routing.md`). The third-party `antigravity-acp` shim is not used. Running agy sessions are adopted, not spawned. …

How to install
mdr add hybridlabor-api/bdb-dev-optimized-agent-skills/master-session@sha256:f55e937d1c7c16feThe line at the top of this page pins the label git:20261020.607a27a, 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.
