Gas Town - Multi-Agent Orchestration for Claude Code
Gas Town coordinates multiple Claude Code instances across projects using gt (agent operations) and bd (beads/data operations).
Core Principles
| Principle | Meaning |
|---|---|
| GUPP | "If there is work on your Hook, YOU MUST RUN IT." No waiting for confirmation. |
| MEOW | Break large goals into atomic, trackable units (beads/molecules). |
| NDI | Eventual completion despite unreliable individual operations. |
The Hook Contract: When you find work on your hook, EXECUTE IMMEDIATELY. The hook IS your assignment.
Quick Orientation
gt hook # What's on my hook?
bd mol current # Where am I in the molecule?
bd ready # What step is next?
bd show <step-id> # What does this step require?
The Propulsion Loop
1. gt hook # What's hooked?
2. bd mol current # Where am I?
3. Execute step
4. bd close <step> --continue # Close and auto-advance
5. GOTO 2
Role Quick Reference
| Role | Purpose | Lifecycle |
|---|---|---|
| Mayor | Town coordinator, initiates convoys | Persistent, town-level |
| Deacon | Background supervisor, health checks | Persistent, daemon |
| Witness | Monitors polecats per rig | Persistent, per-rig |
| Refinery | Merge queue processor | Persistent, per-rig |
| Polecat | Ephemeral worker with worktree | Transient, Witness-managed |
| Crew | Persistent human workspace | Long-lived, user-managed |
See references/roles.md for detailed role documentation.
Essential Commands
Agent Operations (gt)
gt hook # What's on my hook
gt convoy list # Active work batches
gt convoy create "name" <ids> # Create work batch
gt sling <bead> <rig> # Assign work to agent
gt handoff # Session cycling
gt mail inbox # Check messages
gt escalate "topic" # Escalate issue
Beads Operations (bd)
bd ready # Unblocked work
bd show <id> # Issue details
bd create --title="..." # Create issue
bd update <id> --status=... # Update status
bd close <id> --continue # Close and advance
bd sync # Push/pull to git
See references/commands.md for full CLI reference.
Work Units
| Type | Persistence | Purpose |
|---|---|---|
| Bead | Git-backed | Atomic work unit (issue/task) |
| Formula | TOML source | Reusable workflow template |
| Molecule | Persistent | Multi-step workflow instance |
| Wisp | Ephemeral | Lightweight transient work |
| Hook | Pinned | Agent's primary work queue |
| Convoy | Tracking | Batch of related beads |
See references/molecules.md for workflow details.
⚠️ Terminology: "Convoy" Has Two Meanings
IMPORTANT: The word "convoy" refers to TWO completely different concepts:
| Context | What It Is | Command | File/Bead Type |
|---|---|---|---|
| Formula convoy | Parallel execution pattern in Beads formulas | bd mol pour <formula> |
.formula.toml with type = "convoy" |
| Work convoy | Issue tracking unit in Gastown | gt convoy create |
hq-cv-* bead |
Formula Convoy (Beads Concept)
- Purpose: Execute multiple tasks in parallel, then synthesize results
- Structure: Multiple
[[legs]]+ one[synthesis]step - Example:
code-review.formula.toml- 10 reviewers analyze code in parallel, synthesis combines findings - Used in: Multi-perspective analysis (design exploration, code review, architecture options)
Work Convoy (Gastown Concept)
- Purpose: Track batch of related issues across rigs for visibility
- Structure: Single
hq-cv-*bead that tracks multiple issue IDs - Example:
gt convoy create "Feature X" gt-abc gt-def- dashboard shows progress - Used in: Monitoring work completion, cross-rig coordination, notifications
How They Can Work Together
A formula convoy can create issues that get tracked by a work convoy:
# 1. Pour a convoy formula (parallel design exploration)
bd mol pour design-convoy --var feature="auth"
# Creates: design.explore-1, design.explore-2, design.arch, design.synthesis
# 2. Create work convoy to track all those issues
gt convoy create "Design: Auth feature" design.explore-1 design.explore-2 design.arch design.synthesis
# 3. Sling each leg to spawn polecats
gt sling design.explore-1 gastown
gt sling design.explore-2 gastown
# etc.
# 4. gt convoy status shows progress across all legs
Bottom line: They're separate layers. Formula convoy = execution pattern. Work convoy = tracking mechanism.
Directory Structure

Startup Behavior
- Check hook (
gt hook) - Work hooked -> EXECUTE immediately
- Hook empty -> Check mail for attached work
- Nothing anywhere -> ERROR: escalate to Witness
Session Cycling
When context fills or you finish a chunk:
/handoff # Or gt handoff
What persists: Hooked molecule, beads state, git state What resets: Conversation context, TodoWrite items, in-memory state
