# Gas Town

Multi-agent orchestrator for Claude Code. Sling work to agents; they run it.

## Why Gas Town?

| Without | With Gas Town |
|---------|---------------|
| Agents forget work after restart | Work persists on hooks - survives crashes, compaction, restarts |
| Manual coordination | Agents have mailboxes, identities, and structured handoffs |
| 4-10 agents is chaotic | Comfortably scale to 20-30 agents |
| Work state in agent memory | Work state in Beads (git-backed ledger) |

## Quick Start

```bash
# Install
go install github.com/steveyegge/gastown/cmd/gt@latest

# Create workspace
gt install ~/gt

# Add a project
gt rig add myproject --remote=https://github.com/you/repo.git

# Sling work to a polecat (worker)
gt sling issue-123 myproject
```

## Core Concepts

```
Town (~/gt/)              Your workspace
├── Rig (project)         Container for a git project + its agents
│   ├── Polecats          Workers (ephemeral, spawn → work → disappear)
│   ├── Witness           Monitors workers, handles lifecycle
│   └── Refinery          Merge queue processor
└── Mayor                 Global coordinator
```

**Hook**: Each agent has a hook where work hangs. On wake, run what's on your hook.

**Beads**: Git-backed issue tracker. All work state lives here. [github.com/steveyegge/beads](https://github.com/steveyegge/beads)

## Workflows

### Minimal (No Tmux)
Run individual Claude Code instances manually. Gas Town just tracks state.
```bash
gt sling issue-123 myproject      # Creates work assignment
claude --resume                    # Agent reads mail, runs work
```

### Full Stack (Tmux)
Agents run in tmux sessions. Daemon manages lifecycle.
```bash
gt daemon start                    # Start lifecycle manager
gt sling issue-123 myproject       # Spawns polecat automatically
```

### Pick Your Roles
Gas Town is modular. Run what you need:
- **Polecats only**: Manual spawning, no monitoring
- **+ Witness**: Automatic worker lifecycle, stuck detection
- **+ Refinery**: Merge queue, code review
- **+ Mayor**: Cross-project coordination

## Cooking Formulas

Formulas define structured workflows. Cook them, sling them to agents.

### Basic Example

```toml
# .beads/formulas/shiny.formula.toml
formula = "shiny"
description = "Design before code, review before ship"

[[steps]]
id = "design"
description = "Think about architecture"

[[steps]]
id = "implement"
needs = ["design"]

[[steps]]
id = "test"
needs = ["implement"]

[[steps]]
id = "submit"
needs = ["test"]
```

### Using Formulas

```bash
bd formula list                    # See available formulas
bd cook shiny                      # Cook into a protomolecule
bd mol pour shiny --var feature=auth   # Create runnable molecule
gt sling gt-xyz myproject          # Assign to worker
```

### What Happens

1. **Cook** expands the formula into a protomolecule (frozen template)
2. **Pour** creates a molecule (live workflow) with steps as beads
3. **Worker executes** each step, closing beads as it goes
4. **Crash recovery**: Worker restarts, reads molecule, continues from last step

### Example: Beads Release Molecule

A real workflow for releasing a new beads version:

```toml
formula = "beads-release"
description = "Version bump and release workflow"

[[steps]]
id = "bump-version"
description = "Update version in version.go and CHANGELOG"

[[steps]]
id = "update-deps"
needs = ["bump-version"]
description = "Run go mod tidy, update go.sum"

[[steps]]
id = "run-tests"
needs = ["update-deps"]
description = "Full test suite, check for regressions"

[[steps]]
id = "build-binaries"
needs = ["run-tests"]
description = "Cross-compile for all platforms"

[[steps]]
id = "create-tag"
needs = ["build-binaries"]
description = "Git tag with version, push to origin"

[[steps]]
id = "publish-release"
needs = ["create-tag"]
description = "Create GitHub release with binaries"
```

Cook it, pour it, sling it. The polecat runs through each step, and if it crashes
after `run-tests`, a new polecat picks up at `build-binaries`.

### Formula Composition

```toml
# Extend an existing formula
formula = "shiny-enterprise"
extends = ["shiny"]

[compose]
aspects = ["security-audit"]  # Add cross-cutting concerns
```

## Key Commands

### For Humans (Overseer)

```bash
gt start                          # Start Gas Town (daemon + agents)
gt shutdown                       # Graceful shutdown
gt status                         # Town overview
gt <role> attach                  # Jump into any agent session
                                  # e.g., gt mayor attach, gt witness attach
```

Most other work happens through agents - just ask them.

### For Agents

```bash
# Work
gt sling <bead> <rig>             # Assign work to polecat
bd ready                          # Show available work
bd list --status=in_progress      # Active work

# Communication
gt mail inbox                     # Check messages
gt mail send <addr> -s "..." -m "..."

# Lifecycle
gt handoff                        # Request session cycle
gt peek <agent>                   # Check agent health

# Diagnostics
gt doctor                         # Health check
gt doctor --fix                   # Auto-repair
```

## Roles

| Role | Scope | Job |
|------|-------|-----|
| **Overseer** | Human | Sets strategy, reviews output, handles escalations |
| **Mayor** | Town-wide | Cross-rig coordination, work dispatch |
| **Deacon** | Town-wide | Daemon process, agent lifecycle, plugin execution |
| **Witness** | Per-rig | Monitor polecats, nudge stuck workers |
| **Refinery** | Per-rig | Merge queue, PR review, integration |
| **Polecat** | Per-task | Execute work, file discovered issues, request shutdown |

## The Propulsion Principle

> If your hook has work, RUN IT.

Agents wake up, check their hook, execute the molecule. No waiting for commands.
Molecules survive crashes - any agent can continue where another left off.

### States of Matter

| Phase | Name | Storage | Behavior |
|-------|------|---------|----------|
| Ice-9 | Formula | `.beads/formulas/` | Source template, composable |
| Solid | Protomolecule | `.beads/` | Frozen template, reusable |
| Liquid | Mol | `.beads/` | Flowing work, persistent |
| Vapor | Wisp | `.beads/` (ephemeral flag) | Transient, for patrols |

*(Protomolecules are an homage to The Expanse. Ice-9 is a nod to Vonnegut.)*

### Operators

| Operator | From → To | Effect |
|----------|-----------|--------|
| `cook` | Formula → Protomolecule | Expand macros, flatten |
| `pour` | Proto → Mol | Instantiate as persistent |
| `wisp` | Proto → Wisp | Instantiate as ephemeral |
| `squash` | Mol/Wisp → Digest | Condense to permanent record |
| `burn` | Wisp → ∅ | Discard without record |
