 # Gas Town
 
-**Enterprise-grade cognitive processing for AI agent swarms.**
+Multi-agent workspace manager for AI coding agents.
 
-Gas Town is a multi-agent workspace manager that coordinates AI coding agents working on software projects. It provides the infrastructure for spawning workers, processing work through structured workflows (molecules), and coordinating agents through a unified data plane (Beads).
+Gas Town coordinates swarms of AI agents working on software projects. Workers (polecats) implement features and fix bugs. Refineries review and merge code. Witnesses manage worker lifecycles. Mayors coordinate across projects.
 
-## The Idea
+## Install
 
-Traditional AI coding assistants help you write code. Gas Town **writes code for you**.
-
-Instead of AI as autocomplete, Gas Town treats AI agents as workers:
-- **Polecats** implement features and fix bugs
-- **Refineries** review and merge code
-- **Witnesses** manage worker lifecycle
-- **Mayors** coordinate across projects
-
-Work flows through **molecules** - structured workflow templates that encode quality gates, dependencies, and recovery checkpoints. Any worker can continue any workflow from where another left off.
-
-## Key Features
-
-- **Nondeterministic Idempotence**: Workflows survive crashes, context compaction, and agent restarts
-- **Molecule-Based Quality**: Structured workflows with built-in gates, not prompt-based instructions
-- **Unified Data Plane**: All state in Beads (issues, messages, workflows) - queryable, auditable, persistent
-- **Hierarchical Coordination**: Mayor → Witness → Refinery → Polecat chain of command
-- **Federation Ready**: Multiple rigs across machines, coordinated through Beads sync

 ## Quick Start
 
 ```bash
-# Install
-go install github.com/steveyegge/gastown/cmd/gt@latest
-
 # Create a town (workspace)
-gt install ~/gt --git
+gt install ~/gt
 
-# Add a rig for your project
+# Add a project rig
 gt rig add myproject --remote=https://github.com/you/myproject.git
 
-# Spawn a polecat to work on an issue
-gt spawn --issue myproject-123 --molecule mol-engineer-in-box
+# Spawn a worker on an issue
+gt spawn --issue myproject-123
 ```

+## Key Concepts
 
-## Molecules
-
-Molecules are structured workflow templates:
-
-```markdown
-## Molecule: engineer-in-box
-Full workflow from design to merge.
-
-## Step: design
-Think carefully about architecture.
-Write a brief design summary.
-
-## Step: implement
-Write the code. Follow codebase conventions.
-Needs: design
-
-## Step: test
-Write and run tests. Cover edge cases.
-Needs: implement
-
-## Step: submit
-Submit for merge via refinery.
-Needs: test
-```
-
-Built-in molecules:
-- `mol-engineer-in-box` - Full quality workflow (design → implement → review → test → submit)
-- `mol-quick-fix` - Fast path for small changes (implement → test → submit)
-- `mol-research` - Exploration workflow (investigate → document)
-
-## Beads
-
-Gas Town uses [Beads](https://github.com/steveyegge/beads) for issue tracking and coordination:
-
-```bash
-bd ready              # Show work ready to start
-bd list --status=open # All open issues
-bd show gt-123        # Issue details
-bd create --title="Fix auth bug" --type=bug
-bd close gt-123       # Mark complete
-```

 ## Commands
 
 ```bash
-# Town management
-gt install <path>     # Create new town
-gt status             # Overall status
-gt doctor             # Diagnose issues
-
-# Rig management
-gt rig add <name>     # Add project rig
+gt status             # Town status
 gt rig list           # List rigs
-
-# Worker management
-gt spawn --issue <id> # Start polecat on issue
-gt polecat list <rig> # List polecats
-
-# Communication
+gt spawn --issue <id> # Start worker
 gt mail inbox         # Check messages
-gt mail send <addr>   # Send message
 ```
 
-## Status
-
-**Work in Progress** - This is the Go rewrite of the Python gastown tool.
-
-See [gastown-py](https://github.com/steveyegge/gastown-py) for the Python version.
