Thrum - Git-Backed Agent Messaging
Run thrum prime for full session context (auto-injected by hooks on
SessionStart and PreCompact).
Quick Command Reference
Messaging
thrum send "msg" --to @name Direct message (canonical form)
thrum send "msg" --broadcast Explicit team-wide fanout
thrum send "msg" --to @everyone Broadcast (legacy keyword; --broadcast preferred)
thrum reply <msg-id> "response" Reply (same audience)
thrum inbox List messages (auto-marks displayed as read)
thrum inbox --unread Unread only (does not mark as read)
thrum sent List messages you sent
thrum sent --unread Sent messages with unread recipients
thrum message read --all Mark all messages as read
thrum wait Block until message arrives (30s timeout)
thrum wait --timeout 120s Custom timeout (duration)
Agents
thrum quickstart --name <agent-name> --role R --module M --intent "..." Register + start session
thrum worktree create <name> --name <agent> --role R --module M Create worktree + register agent
(then run `thrum tmux launch <name>` to start runtime)
thrum worktree setup <name> --name <agent> --role R --module M Alias for worktree create
thrum whoami Show identity
thrum team List active agents
thrum ping @name Check if agent online
thrum who-has <file> Who's editing a file
Role Templates
thrum roles list List templates + matching agents
thrum roles deploy Re-render preambles from templates
thrum roles deploy --agent foo Deploy for specific agent
thrum roles deploy --dry-run Preview without writing
Sessions & Context
thrum session start Start session
thrum session end End session
thrum session set-intent "..." Update work description
thrum context show Show saved work context
thrum context save --file <path> Save context from file
thrum overview Combined status + team + inbox
/thrum:update-project Guided project state update (narrative + state)
/thrum:load-context Restore work context after compaction
Tmux Sessions (Recommended)
thrum tmux start Launch agent session (create+launch+prime+attach)
thrum tmux status Show managed sessions with state
thrum tmux connect Attach to running session (interactive picker)
thrum tmux restart <name> Restart session with context snapshot
thrum tmux kill <name> Tear down session
thrum tmux create <session> --name <n> --role <r> --module <m> --cwd <path> Create + register agent
thrum tmux quickstart <session> --name <n> --role <r> --module <m> --cwd <path> Alias for tmux create
thrum tmux launch <session> [--runtime <r>] Start runtime in session (REQUIRED after `tmux create`)
Monitor Jobs
thrum monitor add <name> --cmd "..." --on-match "msg" Add a monitored process
thrum monitor list List all monitor jobs
thrum monitor show <name> Show job details and recent matches
thrum monitor stop <name> Stop a monitor job
thrum monitor logs <name> Tail job output
thrum monitor restart <name> Restart a stopped job
Daemon & Sync
thrum daemon start Start daemon
thrum daemon stop Stop daemon
thrum daemon status Daemon health
thrum sync force Force immediate sync
thrum sync status Sync state
Utility
thrum init Initialize thrum in repo (also starts the daemon)
thrum prime Full session context
thrum prime --json Machine-readable output
thrum <cmd> --help Detailed command usage
When to Use Thrum
| Thrum | TaskList/SendMessage | Neither |
|---|
| Cross-worktree messaging | Same-session task tracking | Single-agent, no coordination |
| Persistent messages (survive compaction) | Ephemeral task lists | Temporary scratch notes |
| Background listener pattern | Inline progress tracking | Simple linear execution |
| Multi-machine sync via git | Local to conversation | No persistence needed |
Decision test: "Do messages need to survive session restart or reach agents
in other worktrees?" YES = Thrum.
Thrum + TaskList coexist: Use TaskList for immediate session work. Use Thrum
for cross-session/cross-worktree coordination messages.
Message Delivery
Tmux Sessions (Recommended)
When running in a tmux-managed session, messages are delivered directly to your
pane via daemon nudge — zero token cost, no background sub-agent needed. See
TMUX_SESSIONS.md.
Listener Pattern (Fallback)
When tmux is not available, use the background message listener. It calls
thrum wait (blocking) and returns when messages arrive. Re-arm after
processing. See LISTENER_PATTERN.md.
Context Management
thrum prime gathers identity, team, inbox, git context, sync health- SessionStart hook auto-runs
thrum prime on session start
- PreCompact hook saves state to thrum context +
/tmp backup before compaction
- After compaction: run
/thrum:load-context to restore your work context
- Agent identity persists in
.thrum/identities/
Resources
Run thrum <command> --help for any command's full usage.
