When gt done runs inside a tmux session (e.g., after polecat task completion), calling KillSessionWithProcesses would kill the gt done process itself before it could complete cleanup operations like writing handoff state. Add KillSessionWithProcessesExcluding() function that accepts a list of PIDs to exclude from the kill sequence. Update selfKillSession to pass its own PID, ensuring gt done completes before the session is destroyed. Also fix both Kill*WithProcesses functions to ignore "session not found" errors from KillSession - when we kill all processes in a session, tmux may automatically destroy it before we explicitly call KillSession.

Gas Town
Multi-agent orchestration system for Claude Code with persistent work tracking
Overview
Gas Town is a workspace manager that lets you coordinate multiple Claude Code agents working on different tasks. Instead of losing context when agents restart, Gas Town persists work state in git-backed hooks, enabling reliable multi-agent workflows.
What Problem Does This Solve?
| Challenge | Gas Town Solution |
|---|---|
| Agents lose context on restart | Work persists in git-backed hooks |
| Manual agent coordination | Built-in mailboxes, identities, and handoffs |
| 4-10 agents become chaotic | Scale comfortably to 20-30 agents |
| Work state lost in agent memory | Work state stored in Beads ledger |

Core Concepts
The Mayor 🎩
Your primary AI coordinator. The Mayor is a Claude Code instance with full context about your workspace, projects, and agents. Start here - just tell the Mayor what you want to accomplish.
Town 🏘️
Your workspace directory (e.g., ~/gt/). Contains all projects, agents, and configuration.
Rigs 🏗️
Project containers. Each rig wraps a git repository and manages its associated agents.
Crew Members 👤
Your personal workspace within a rig. Where you do hands-on work.
Polecats 🦨
Ephemeral worker agents that spawn, complete a task, and disappear.
Hooks 🪝
Git worktree-based persistent storage for agent work. Survives crashes and restarts.
Convoys 🚚
Work tracking units. Bundle multiple beads that get assigned to agents.
Beads Integration 📿
Git-backed issue tracking system that stores work state as structured data.
Bead IDs (also called issue IDs) use a prefix + 5-character alphanumeric format (e.g., gt-abc12, hq-x7k2m). The prefix indicates the item's origin or rig. Commands like gt sling and gt convoy accept these IDs to reference specific work items. The terms "bead" and "issue" are used interchangeably—beads are the underlying data format, while issues are the work items stored as beads.

Quick Start Guide
Getting Started
Run
gt install ~/gt --git &&
cd ~/gt &&
gt config agent list &&
gt mayor attach
and tell the Mayor what you want to build!
Basic Workflow
sequenceDiagram
participant You
participant Mayor
participant Convoy
participant Agent
participant Hook
You->>Mayor: Tell Mayor what to build
Mayor->>Convoy: Create convoy with beads
Mayor->>Agent: Sling bead to agent
Agent->>Hook: Store work state
Agent->>Agent: Complete work
Agent->>Convoy: Report completion
Mayor->>You: Summary of progress
Example: Feature Development
# 1. Start the Mayor
gt mayor attach
# 2. In Mayor session, create a convoy with bead IDs
gt convoy create "Feature X" gt-abc12 gt-def34 --notify --human
# 3. Assign work to an agent
gt sling gt-abc12 myproject
# 4. Track progress
gt convoy list
# 5. Monitor agents
gt agents
Common Workflows
Mayor Workflow (Recommended)
Best for: Coordinating complex, multi-issue work
flowchart LR
Start([Start Mayor]) --> Tell[Tell Mayor<br/>what to build]
Tell --> Creates[Mayor creates<br/>convoy + agents]
Creates --> Monitor[Monitor progress<br/>via convoy list]
Monitor --> Done{All done?}
Done -->|No| Monitor
Done -->|Yes| Review[Review work]
Commands:
# Attach to Mayor
gt mayor attach
# In Mayor, create convoy and let it orchestrate
gt convoy create "Auth System" gt-x7k2m gt-p9n4q --notify
# Track progress
gt convoy list
Minimal Mode (No Tmux)
Run individual runtime instances manually. Gas Town just tracks state.
gt convoy create "Fix bugs" gt-abc12 # Create convoy (sling auto-creates if skipped)
gt sling gt-abc12 myproject # Assign to worker
claude --resume # Agent reads mail, runs work (Claude)
# or: codex # Start Codex in the workspace
gt convoy list # Check progress
Beads Formula Workflow
Best for: Predefined, repeatable processes
Formulas are TOML-defined workflows stored in .beads/formulas/.
Example Formula (.beads/formulas/release.formula.toml):
description = "Standard release process"
formula = "release"
version = 1
[vars.version]
description = "The semantic version to release (e.g., 1.2.0)"
required = true
[[steps]]
id = "bump-version"
title = "Bump version"
description = "Run ./scripts/bump-version.sh {{version}}"
[[steps]]
id = "run-tests"
title = "Run tests"
description = "Run make test"
needs = ["bump-version"]
[[steps]]
id = "build"
title = "Build"
description = "Run make build"
needs = ["run-tests"]
[[steps]]
id = "create-tag"
title = "Create release tag"
description = "Run git tag -a v{{version}} -m 'Release v{{version}}'"
needs = ["build"]
[[steps]]
id = "publish"
title = "Publish"
description = "Run ./scripts/publish.sh"
needs = ["create-tag"]
Execute:
# List available formulas
bd formula list
# Run a formula with variables
bd cook release --var version=1.2.0
# Create formula instance for tracking
bd mol pour release --var version=1.2.0
Manual Convoy Workflow
Best for: Direct control over work distribution
# Create convoy manually
gt convoy create "Bug Fixes" --human
# Add issues to existing convoy
gt convoy add hq-cv-abc gt-m3k9p gt-w5t2x
# Assign to specific agents
gt sling gt-m3k9p myproject/my-agent
# Check status
gt convoy show
Runtime Configuration
Gas Town supports multiple AI coding runtimes. Per-rig runtime settings are in settings/config.json.
{
"runtime": {
"provider": "codex",
"command": "codex",
"args": [],
"prompt_mode": "none"
}
}
Notes:
- Claude uses hooks in
.claude/settings.jsonfor mail injection and startup. - For Codex, set
project_doc_fallback_filenames = ["CLAUDE.md"]in~/.codex/config.tomlso role instructions are picked up. - For runtimes without hooks (e.g., Codex), Gas Town sends a startup fallback
after the session is ready:
gt prime, optionalgt mail check --injectfor autonomous roles, andgt nudge deacon session-started.

Cooking Formulas
Gas Town includes built-in formulas for common workflows. See .beads/formulas/ for available recipes.
Dashboard
Gas Town includes a web dashboard for monitoring:
# Start dashboard
gt dashboard --port 8080
# Open in browser
open http://localhost:8080
Features:
- Real-time agent status
- Convoy progress tracking
- Hook state visualization
- Configuration management
Advanced Concepts
The Propulsion Principle
Gas Town uses git hooks as a propulsion mechanism. Each hook is a git worktree with:
- Persistent state - Work survives agent restarts
- Version control - All changes tracked in git
- Rollback capability - Revert to any previous state
- Multi-agent coordination - Shared through git
Hook Lifecycle

MEOW (Mayor-Enhanced Orchestration Workflow)
MEOW is the recommended pattern:
- Tell the Mayor - Describe what you want
- Mayor analyzes - Breaks down into tasks
- Convoy creation - Mayor creates convoy with beads
- Agent spawning - Mayor spawns appropriate agents
- Work distribution - Beads slung to agents via hooks
- Progress monitoring - Track through convoy status
- Completion - Mayor summarizes results
Shell Completions
# Bash
gt completion bash > /etc/bash_completion.d/gt
# Zsh
gt completion zsh > "${fpath[1]}/_gt"
# Fish
gt completion fish > ~/.config/fish/completions/gt.fish
Project Roles
| Role | Description | Primary Interface |
|---|---|---|
| Mayor | AI coordinator | gt mayor attach |
| Human (You) | Crew member | Your crew directory |
| Polecat | Worker agent | Spawned by Mayor |
| Hook | Persistent storage | Git worktree |
| Convoy | Work tracker | gt convoy commands |
Tips
- Always start with the Mayor - It's designed to be your primary interface
- Use convoys for coordination - They provide visibility across agents
- Leverage hooks for persistence - Your work won't disappear
- Create formulas for repeated tasks - Save time with Beads recipes
- Monitor the dashboard - Get real-time visibility
- Let the Mayor orchestrate - It knows how to manage agents
Troubleshooting
Agents lose connection
Check hooks are properly initialized:
gt hooks list
gt hooks repair
Convoy stuck
Force refresh:
gt convoy refresh <convoy-id>
Mayor not responding
Restart Mayor session:
gt mayor detach
gt mayor attach
