+
+Initial public release of Gas Town - a multi-agent workspace manager for Claude Code.
+
+#### Core Architecture
+- **Town structure** - Hierarchical workspace with rigs, crews, and polecats
+- **Rig management** - `gt rig add/list/remove` for project containers
+- **Crew workspaces** - `gt crew add` for persistent developer workspaces
+- **Polecat workers** - Transient agent workers managed by Witness
+
+#### Agent Roles
+- **Mayor** - Global coordinator for cross-rig work
+- **Deacon** - Town-level lifecycle patrol and heartbeat
+- **Witness** - Per-rig polecat lifecycle manager
+- **Refinery** - Merge queue processor with code review
+- **Crew** - Persistent developer workspaces
+- **Polecat** - Transient worker agents
+
+#### Work Management
+- **Convoy system** - `gt convoy create/list/status` for tracking related work
+- **Sling workflow** - `gt sling <bead> <rig>` to assign work to agents
+- **Hook mechanism** - Work attached to agent hooks for pickup
+- **Molecule workflows** - Formula-based multi-step task execution
+
+#### Communication
+- **Mail system** - `gt mail inbox/send/read` for agent messaging
+- **Escalation protocol** - `gt escalate` with severity levels
+- **Handoff mechanism** - `gt handoff` for context-preserving session cycling

+
+#### Developer Experience
+- **Status dashboard** - `gt status` for town overview
+- **Session cycling** - `C-b n/p` to navigate between agents
+- **Activity feed** - `gt feed` for real-time event stream
+- **Nudge system** - `gt nudge` for reliable message delivery to sessions
+
+### Infrastructure
+- **Daemon mode** - Background lifecycle management
+- **npm package** - Cross-platform binary distribution

+# Release Process for Gas Town
+
+This document describes the release process for Gas Town, including GitHub releases and npm packages.
+
+## Table of Contents
+
+- [Overview](#overview)
+- [Prerequisites](#prerequisites)
+- [Release Checklist](#release-checklist)
+- [1. Prepare Release](#1-prepare-release)
+- [2. GitHub Release](#2-github-release)
+- [3. npm Package Release](#3-npm-package-release)

+
+## Overview
+
+A Gas Town release involves multiple distribution channels:
+
+1. **GitHub Release** - Binary downloads for all platforms
+2. **npm** - Node.js package for cross-platform installation (`@gastown/gt`)
+
+## Prerequisites
+
+### Required Tools
+
+- `git` with push access to steveyegge/gastown
+- `goreleaser` for building binaries
+- `npm` with authentication (for npm releases)
+- `gh` CLI (GitHub CLI, recommended)
+
+### Required Access
+
+- GitHub: Write access to repository and ability to create releases
+- npm: Publish access to `@gastown` organization
+
+### Verify Setup
+
+```bash
+# Check git
+git remote -v  # Should show steveyegge/gastown
+
+# Check goreleaser
+goreleaser --version
+
+# Check GitHub CLI
+gh auth status
+
+# Check npm
+npm whoami  # Should show your npm username
+```
+
+## Release Checklist
+
+Before starting a release:
+
+- [ ] All tests passing (`go test ./...`)
+- [ ] npm package tests passing (`cd npm-package && npm test`)
+- [ ] CHANGELOG.md updated with release notes
+- [ ] No uncommitted changes
+- [ ] On `main` branch and up to date with origin
+
+## 1. Prepare Release
+
+### Update CHANGELOG.md
+
+Add release notes to CHANGELOG.md following the Keep a Changelog format:
+
+```markdown
+## [0.2.0] - 2026-01-15
+
+### Added
+- New feature X
+
+### Changed
+- Improved Y
+
+### Fixed
+- Bug in Z
+```
+
+Commit the CHANGELOG changes:
+
+```bash
+git add CHANGELOG.md
+git commit -m "docs: Add CHANGELOG entry for v0.2.0"
+git push origin main
+```
+
+### Update Version
+
+Update version in relevant files:
+
+1. `internal/cmd/version.go` - CLI version constant
+2. `npm-package/package.json` - npm package version
+
+```bash
+# Update versions
+vim internal/cmd/version.go
+vim npm-package/package.json
+
+# Commit
+git add -A
+git commit -m "chore: Bump version to 0.2.0"
+git push origin main
+```
+
+### Create Release Tag
+
+```bash
+git tag -a v0.2.0 -m "Release v0.2.0"
+git push origin v0.2.0
+```
+
+This triggers GitHub Actions to build release artifacts automatically.
+
+## 2. GitHub Release
+
+### Using GoReleaser (Recommended)
+
+GoReleaser automates binary building and GitHub release creation:
+
+```bash
+# Clean any previous builds
+rm -rf dist/
+
+# Create release (uses GITHUB_TOKEN from gh CLI)
+GITHUB_TOKEN=$(gh auth token) goreleaser release --clean
+```
+
+This will:
+- Build binaries for all platforms (macOS, Linux, Windows - amd64/arm64)
+- Create checksums
+- Generate release notes from CHANGELOG.md
+- Upload everything to GitHub releases
+
+### Verify GitHub Release
+
+1. Visit https://github.com/steveyegge/gastown/releases
+2. Verify the new version is marked as "Latest"
+3. Check all platform binaries are present
+
+## 3. npm Package Release
+
+The npm package wraps the native binary for Node.js environments.
+
+### Test Installation Locally
+
+```bash
+cd npm-package
+
+# Run tests
+npm test
+
+# Pack and test install
+npm pack
+npm install -g ./gastown-gt-0.2.0.tgz
+gt version  # Should show 0.2.0
+
+# Cleanup
+npm uninstall -g @gastown/gt
+rm gastown-gt-0.2.0.tgz
+```
+
+### Publish to npm
+
+```bash
+# IMPORTANT: Ensure GitHub release with binaries is live first!
+cd npm-package
+npm publish --access public
+```
+
+### Verify npm Release
+
+```bash
+npm install -g @gastown/gt
+gt version  # Should show 0.2.0
+```
+
+## 4. Verify Release
+
+After all channels are updated:
+
+### GitHub
+
+```bash
+# Download and test binary
+curl -LO https://github.com/steveyegge/gastown/releases/download/v0.2.0/gastown_0.2.0_darwin_arm64.tar.gz
+tar -xzf gastown_0.2.0_darwin_arm64.tar.gz
+./gt version
+```
+
+### npm
+
+```bash
+npm install -g @gastown/gt
+gt version
+```
+
+## Hotfix Releases
+
+For urgent bug fixes:
+
+```bash
+# Create hotfix branch from tag
+git checkout -b hotfix/v0.2.1 v0.2.0
+
+# Make fixes and bump version
+# ... edit files ...
+
+# Commit, tag, and release
+git add -A
+git commit -m "fix: Critical bug fix"
+git tag -a v0.2.1 -m "Hotfix release v0.2.1"
+git push origin hotfix/v0.2.1
+git push origin v0.2.1
+
+# Follow normal release process
+GITHUB_TOKEN=$(gh auth token) goreleaser release --clean
+
+# Merge back to main
+git checkout main
+git merge hotfix/v0.2.1
+git push origin main
+```
