-Review all documentation files:
-- docs/*.md (primary documentation)
-- README.md (repository landing page)
-- CLAUDE.md (development guidelines)
-- examples/README.md (example configurations)
+Don't waste time on these—CI and pre-commit hooks handle them:

+- **README help output**: `markdown-code-runner` regenerates `cf --help` blocks in CI
+- **README command table**: Pre-commit hook verifies commands are listed
+- **Linting/formatting**: Handled by pre-commit
 
-### 1. Command Documentation
+## What This Review Is For
 
-For each documented command, verify against the CLI source code:
+Focus on things that require judgment:
 
-- Command exists in codebase
-- All options are documented with correct names, types, and defaults
-- Short options (-x) match long options (--xxx)
-- Examples would work as written
-- Check for undocumented commands or options
+1. **Accuracy**: Does the documentation match what the code actually does?
+2. **Completeness**: Are there undocumented features, options, or behaviors?
+3. **Clarity**: Would a new user understand this? Are examples realistic?
+4. **Consistency**: Do different docs contradict each other?
+5. **Freshness**: Has the code changed in ways the docs don't reflect?
 
-Run `--help` for each command to verify.
+## Review Process
 
-### 2. Configuration Documentation
+### 1. Check Recent Changes
 
-Verify against Pydantic models in the config module:
+```bash
+# What changed recently that might need doc updates?
+git log --oneline -20 | grep -iE "feat|fix|add|remove|change|option"
 
-- All config keys are documented
-- Types match Pydantic field types
-- Required vs optional fields are correct
-- Default values are accurate
-- Config file search order matches code
-- Example YAML is valid and uses current schema
+# What code files changed?
+git diff --name-only HEAD~20 | grep "\.py$"
+```
 
-### 3. Architecture Documentation
+Look for new features, changed defaults, renamed options, or removed functionality.
 
-Verify against actual directory structure:
+### 2. Verify docs/commands.md Options Tables
 
-- File paths match actual source code location
-- All modules listed actually exist
-- No modules are missing from the list
-- Component descriptions match code functionality
-- CLI module list includes all command files
+The README auto-updates help output, but `docs/commands.md` has **manually maintained options tables**. These can drift.
 
-### 4. State and Data Files
+For each command's options table, compare against `cf <command> --help`:
+- Are all options listed?
+- Are short flags correct?
+- Are defaults accurate?
+- Are descriptions accurate?
 
-Verify against state and path modules:
+**Pay special attention to subcommands** (`cf config *`, `cf ssh *`)—these have their own options that are easy to miss.
 
-- State file name and location are correct
-- State file format matches actual structure
-- Log file name and location are correct

+# Duplication audit and generalization prompt
+
+You are a coding agent working inside a repository. Your job is to find duplicated
+functionality (not just identical code) and propose a minimal, safe generalization.
+Keep it simple and avoid adding features.
+
+## First steps
+
+- Read project-specific instructions (AGENTS.md, CONTRIBUTING.md, or similar) and follow them.
+- If instructions mention tooling or style (e.g., preferred search tools), use those.
+- Ask a brief clarification if the request is ambiguous (for example: report only vs refactor).
+
+## Objective
+
+Identify and consolidate duplicated functionality across the codebase. Duplication includes:
+- Multiple functions that parse or validate the same data in slightly different ways
+- Repeated file reads or config parsing
+- Similar command building or subprocess execution paths
+- Near-identical error handling or logging patterns
+- Repeated data transforms that can become a shared helper
+
+The goal is to propose a general, reusable abstraction that reduces duplication while
+preserving behavior. Keep changes minimal and easy to review.
+
+## Search strategy
+
+1) Map the hot paths
+- Scan entry points (CLI, web handlers, tasks, jobs) to see what they do repeatedly.
+- Look for cross-module patterns: same steps, different files.
+
+2) Find duplicate operations
+- Use fast search tools (prefer `rg`) to find repeated keywords and patterns.
+- Check for repeated YAML/JSON parsing, env interpolation, file IO, command building,
+  data validation, or response formatting.
+
+3) Validate duplication is real
+- Confirm the functional intent matches (not just similar code).
+- Note any subtle differences that must be preserved.
+
+4) Propose a minimal generalization
+- Suggest a shared helper, utility, or wrapper.
+- Avoid over-engineering. If only two call sites exist, keep the helper small.
+- Prefer pure functions and centralized IO if that already exists.
+
+## Deliverables
+
+Provide a concise report with:
+
+1) Findings
+- List duplicated behaviors with file references and a short description of the
+  shared functionality.
+- Explain why these are functionally the same (or nearly the same).
+
+2) Proposed generalizations
+- For each duplication, propose a shared helper and where it should live.
+- Outline any behavior differences that need to be parameterized.
+
+3) Impact and risk
+- Note any behavior risks, test needs, or migration steps.
+
+If the user asked you to implement changes:
+- Make only the minimal edits needed to dedupe behavior.
+- Keep the public API stable unless explicitly requested.
+- Add small comments only when the logic is non-obvious.
+- Summarize what changed and why.
+
+## Output format
+
+- Start with a short summary of the top 1-3 duplications.
+- Then provide a list of findings, ordered by impact.
+- Include a small proposed refactor plan (step-by-step, no more than 5 steps).
+- End with any questions or assumptions.
+
+## Guardrails
+
+- Do not add new features or change behavior beyond deduplication.
+- Avoid deep refactors without explicit request.
+- Preserve existing style conventions and import rules.
+- If a duplication is better left alone (e.g., clarity, single usage), say so.

+Update demo recordings to match the current compose-farm.yaml configuration.
+
+## Key Gotchas
+
+1. **Never `git checkout` without asking** - check for uncommitted changes first
+2. **Prefer `nas` stacks** - demos run locally on nas, SSH adds latency
+3. **Terminal captures keyboard** - use `blur()` to release focus before command palette
+4. **Clicking sidebar navigates away** - clicking h1 scrolls to top
+5. **Buttons have icons, not text** - use `[data-tip="..."]` selectors
+6. **`record.py` auto-restores config** - no manual cleanup needed after CLI demos
+
+## Stacks Used in Demos
+
+| Stack | CLI Demos | Web Demos | Notes |
+|-------|-----------|-----------|-------|
+| `audiobookshelf` | quickstart, migration, apply | - | Migrates nas→anton |
+| `grocy` | update | navigation, stack, workflow, console | - |
+| `immich` | logs, compose | shell | Multiple containers |
+| `dozzle` | - | workflow | - |
+
+## CLI Demos
+
+**Files:** `docs/demos/cli/*.tape`
+
+Check:
+- `quickstart.tape`: `bat -r` line ranges match current config structure
+- `migration.tape`: nvim keystrokes work, stack exists on nas
+- `compose.tape`: exec commands produce meaningful output
+
+Run: `python docs/demos/cli/record.py [demo]`
+
+## Web Demos
+
+**Files:** `docs/demos/web/demo_*.py`
+
+Check:
+- Stack names in demos still exist in config
+- Selectors match current templates (grep for IDs in `templates/`)
+- Shell demo uses command palette for ALL navigation
+
+Run: `python docs/demos/web/record.py [demo]`
+
+## Before Recording

 4. **SSH key auth only**: Uses ssh-agent, no password handling (YAGNI)
 5. **NFS assumption**: Compose files at same path on all hosts

+7. **State tracking**: Tracks where stacks are deployed for auto-migration
 8. **Pre-flight checks**: Verifies NFS mounts and Docker networks exist before starting/migrating
 
 ## Code Style
 
 - **Imports at top level**: Never add imports inside functions unless they are explicitly marked with `# noqa: PLC0415` and a comment explaining it speeds up CLI startup. Heavy modules like `pydantic`, `yaml`, and `rich.table` are lazily imported to keep `cf --help` fast.

-# Docker Swarm Overlay Networks with Compose Farm
-
-Notes from testing Docker Swarm's attachable overlay networks as a way to get cross-host container networking while still using `docker compose`.
-
-## The Idea
-
-Docker Swarm overlay networks can be made "attachable", allowing regular `docker compose` containers (not just swarm services) to join them. This would give us:
-
-- Cross-host Docker DNS (containers find each other by name)
-- No need to publish ports for inter-container communication
-- Keep using `docker compose up` instead of `docker stack deploy`
-
-## Setup Steps
-
-```bash
-# On manager node
-docker swarm init --advertise-addr <manager-ip>
-
-# On worker nodes (use token from init output)
-docker swarm join --token <token> <manager-ip>:2377
-
-# Create attachable overlay network (on manager)
-docker network create --driver overlay --attachable my-network
-
-# In compose files, add the network
-networks:
-  my-network:
-    external: true
-```
-
-## Required Ports
-
-Docker Swarm requires these ports open **bidirectionally** between all nodes:
-
-| Port | Protocol | Purpose |
-|------|----------|---------|
-| 2377 | TCP | Cluster management |
-| 7946 | TCP + UDP | Node communication |
-| 4789 | UDP | Overlay network traffic (VXLAN) |
-
-## Test Results (2024-12-13)
-
-- docker-debian (192.168.1.66) as manager
-- dev-lxc (192.168.1.167) as worker
-
-### What worked
-
-- Swarm init and join
-- Overlay network creation
-- Nodes showed as Ready
-
-### What failed
-
-- Container on dev-lxc couldn't attach to overlay network
-- Error: `attaching to network failed... context deadline exceeded`
-- Cause: Port 7946 blocked from docker-debian → dev-lxc
-
-### Root cause
-
-Firewall on dev-lxc wasn't configured to allow swarm ports. Opening these ports requires sudo access on each node.
-
-## Conclusion
-
-Docker Swarm overlay networks are **not plug-and-play**. Requirements:
-
-1. Swarm init/join on all nodes
-2. Firewall rules on all nodes (needs sudo/root)
-3. All nodes must have bidirectional connectivity on 3 ports
-
-For a simpler alternative, consider:
-
-- **Tailscale**: VPN mesh, containers use host's Tailscale IP
-- **Host networking + published ports**: What compose-farm does today
-- **Keep dependent services together**: Avoid cross-host networking entirely
-
-## Future Work
-
-If we decide to support overlay networks:
-
-1. Add a `compose-farm network create` command that:
-   - Initializes swarm if needed
-   - Creates attachable overlay network
-   - Documents required firewall rules
-
-2. Add network config to compose-farm.yaml:
-   ```yaml
-   overlay_network: compose-farm-net
-   ```
-
-3. Auto-inject network into compose files (or document manual setup)

-# Future Improvements
-
-Low-priority improvements identified during code review. These are not currently causing issues but could be addressed if they become pain points.
-
-## 1. State Module Efficiency (LOW)
-
-**Current:** Every state operation reads and writes the entire file.
-
-```python
-def set_service_host(config, service, host):
-    state = load_state(config)   # Read file
-    state[service] = host
-    save_state(config, state)    # Write file
-```
-
-**Impact:** With 87 services, this is fine. With 1000+, it would be slow.
-
-**Potential fix:** Add batch operations:
-```python
-def update_state(config, updates: dict[str, str | None]) -> None:
-    """Batch update: set services to hosts, None means remove."""
-    state = load_state(config)
-    for service, host in updates.items():
-        if host is None:
-            state.pop(service, None)
-        else:
-            state[service] = host
-    save_state(config, state)
-```
-
-**When to do:** Only if state operations become noticeably slow.
-
----
-
-## 2. Remote-Aware Compose Path Resolution (LOW)
-
-**Current:** `config.get_compose_path()` checks if files exist on the local filesystem:
-
-```python
-def get_compose_path(self, service: str) -> Path:
-    for filename in ("compose.yaml", "compose.yml", ...):
-        candidate = service_dir / filename
-        if candidate.exists():  # Local check!
-            return candidate
-```
-
-**Why this works:** NFS/shared storage means local = remote.
-
-**Why it could break:** If running compose-farm from a machine without the NFS mount, it returns `compose.yaml` (the default) even if `docker-compose.yml` exists on the remote host.
-
-**Potential fix:** Query the remote host for file existence, or accept this limitation and document it.
-
-**When to do:** Only if users need to run compose-farm from non-NFS machines.
-
----
-
-## 3. Add Integration Tests for CLI Commands (MEDIUM)
-
-**Current:** No integration tests for the actual CLI commands. Tests cover the underlying functions but not the Typer commands themselves.
-
-**Potential fix:** Add integration tests using `CliRunner` from Typer:
-
-```python
-from typer.testing import CliRunner
-from compose_farm.cli import app
-
-runner = CliRunner()
-
-def test_check_command_validates_config():
-    result = runner.invoke(app, ["check", "--local"])
-    assert result.exit_code == 0
-```
-
-**When to do:** When CLI behavior becomes complex enough to warrant dedicated testing.
-
----
-
-## 4. Add Tests for operations.py (MEDIUM)
-
-**Current:** Operations module has 30% coverage. Most logic is tested indirectly through test_sync.py.
-
-**Potential fix:** Add dedicated tests for:
-- `up_services()` with migration scenarios
-- `preflight_check()`
-- `check_host_compatibility()`
-
-**When to do:** When adding new operations or modifying migration logic.
-
----
-
-## 5. Consider Structured Logging (LOW)
-
-**Current:** Operations print directly to console using Rich. This couples the operations module to the Rich library.
-
-**Potential fix:** Use Python's logging module with a custom Rich handler:
-
-```python
-import logging
-
-logger = logging.getLogger(__name__)
-
-# In operations:
-logger.info("Migrating %s from %s to %s", service, old_host, new_host)
-
-# In cli.py - configure Rich handler:
-from rich.logging import RichHandler
-logging.basicConfig(handlers=[RichHandler()])
-```
-
-**Benefits:**
-- Operations become testable without capturing stdout
-- Logs can be redirected to files
-- Log levels provide filtering
-
-**When to do:** Only if console output coupling becomes a problem for testing or extensibility.
-
----
-
-## Design Decisions to Keep
-
-These patterns are working well and should be preserved:
-
-1. **asyncio + asyncssh** - Solid async foundation
-2. **Pydantic models** - Clean validation
-3. **Rich for output** - Good UX
-4. **Test structure** - Good coverage
-5. **Module separation** - cli/operations/executor/compose pattern
-6. **KISS principle** - Don't over-engineer

+# Docker Deployment
+
+Run the Compose Farm web UI in Docker.
+
+## Quick Start
+
+**1. Get the compose file:**
+
+```bash
+curl -O https://raw.githubusercontent.com/basnijholt/compose-farm/main/docker-compose.yml
+```
+
+**2. Generate `.env` file:**
+
+```bash
+cf config init-env -o .env
+```
+
+This auto-detects settings from your `compose-farm.yaml`:
+- `DOMAIN` from existing traefik labels
+- `CF_COMPOSE_DIR` from config
+- `CF_UID/GID/HOME/USER` from current user
+- `CF_LOCAL_HOST` by matching local IPs to config hosts
+
+Review the output and edit if needed.
+
+**3. Set up SSH keys:**
+
+```bash
+docker compose run --rm cf ssh setup
+```
+
+**4. Start the web UI:**
+
+```bash
+docker compose up -d web
+```
+
+Open `http://localhost:9000` (or `https://compose-farm.example.com` if using Traefik).
+
+---
+
+## Configuration
+
+The `cf config init-env` command auto-detects most settings. After running it, review the generated `.env` file and edit if needed:
+
+```bash
+$EDITOR .env
+```
+
+### What init-env detects
+
+| Variable | How it's detected |
+|----------|-------------------|
+| `DOMAIN` | Extracted from traefik labels in your stacks |
+| `CF_COMPOSE_DIR` | From `compose_dir` in your config |
+| `CF_UID/GID/HOME/USER` | From current user (for NFS compatibility) |
+| `CF_LOCAL_HOST` | By matching local IPs to configured hosts |
+
+If auto-detection fails for any value, edit the `.env` file manually.
+
+### Glances Monitoring
+
+To show host CPU/memory stats in the dashboard, deploy [Glances](https://nicolargo.github.io/glances/) on your hosts. If `CF_LOCAL_HOST` wasn't detected correctly, set it to your local hostname:
+
+```bash
+CF_LOCAL_HOST=nas  # Replace with your local host name
+```
+
+See [Host Resource Monitoring](https://github.com/basnijholt/compose-farm#host-resource-monitoring-glances) in the README.
+
+---
+
+## Troubleshooting
+
+### SSH "Permission denied" or "Host key verification failed"
+
+Regenerate keys:
+
+```bash
+docker compose run --rm cf ssh setup
+```
+
+### Glances shows error for local host
+
+Add your local hostname to `.env`:
+
+```bash
+echo "CF_LOCAL_HOST=nas" >> .env
+docker compose restart web
+```
+
+### Files created as root
+
+Add the non-root variables above and restart.
+
+---
+
+## All Environment Variables
+
+For advanced users, here's the complete reference:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `DOMAIN` | Domain for Traefik labels | *(required)* |
+| `CF_COMPOSE_DIR` | Compose files directory | `/opt/stacks` |
+| `CF_UID` / `CF_GID` | User/group ID | `0` (root) |
+| `CF_HOME` | Home directory | `/root` |
+| `CF_USER` | Username for SSH | `root` |
+| `CF_LOCAL_HOST` | Local hostname for Glances | *(auto-detect)* |
+| `CF_SSH_DIR` | SSH keys directory | `~/.ssh/compose-farm` |
+| `CF_XDG_CONFIG` | Config/backup directory | `~/.config/compose-farm` |

+# Web UI
+
+Compose Farm includes a web interface for managing stacks from your browser. Start it with:
+
+```bash
+cf web
+```
+
+Then open [http://localhost:8000](http://localhost:8000).
+
+## Features
+
+### Full Workflow
+
+Console terminal, config editor, stack navigation, actions (up, logs, update), dashboard overview, and theme switching - all in one flow.
+
+<video autoplay loop muted playsinline>
+  <source src="/assets/web-workflow.webm" type="video/webm">
+</video>
+
+### Stack Actions
+
+Navigate to any stack and use the command palette to trigger actions like restart, pull, update, or view logs. Output streams in real-time via WebSocket.
+
+<video autoplay loop muted playsinline>
+  <source src="/assets/web-stack.webm" type="video/webm">
+</video>
+
+### Theme Switching
+
+35 themes available via the command palette. Type `theme:` to filter, then use arrow keys to preview themes live before selecting.
+
+<video autoplay loop muted playsinline>
+  <source src="/assets/web-themes.webm" type="video/webm">

+
+### Command Palette
+
+Press `Ctrl+K` (or `Cmd+K` on macOS) to open the command palette. Use fuzzy search to quickly navigate, trigger actions, or change themes.

+## Pages
+
+### Dashboard (`/`)
+
+- Stack overview with status indicators
+- Host statistics (CPU, memory, disk, load via Glances)
+- Pending operations (migrations, orphaned stacks)
+- Quick actions via command palette
+
+### Live Stats (`/live-stats`)
+
+Real-time container monitoring across all hosts, powered by [Glances](https://nicolargo.github.io/glances/).
+
+- **Live metrics**: CPU, memory, network I/O for every container
+- **Auto-refresh**: Updates every 3 seconds (pauses when dropdown menus are open)
+- **Filtering**: Type to filter containers by name, stack, host, or image
+- **Sorting**: Click column headers to sort by any metric
+- **Update detection**: Shows when container images have updates available
+
+<video autoplay loop muted playsinline>
+  <source src="/assets/web-live_stats.webm" type="video/webm">
+</video>
+
+#### Requirements
+
+Live Stats requires Glances to be deployed on all hosts:
+
+1. Add `glances_stack: glances` to your `compose-farm.yaml`
+2. Deploy a Glances stack that runs on all hosts (see [example](https://github.com/basnijholt/compose-farm/tree/main/examples/glances))
+3. Glances must expose its REST API on port 61208
+
+### Stack Detail (`/stack/{name}`)
+
+- Compose file editor (Monaco)
+- Environment file editor
+- Action buttons: Up, Down, Restart, Update, Pull, Logs
+- Container shell access (exec into running containers)
+- Terminal output for running commands
+
+Files are automatically backed up before saving to `~/.config/compose-farm/backups/`.
+
+### Console (`/console`)
+
+- Full shell access to any host
+- File editor for remote files
+- Monaco editor with syntax highlighting
+
+<video autoplay loop muted playsinline>
+  <source src="/assets/web-console.webm" type="video/webm">
+</video>
+
+### Container Shell
+
+Click the Shell button on any running container to exec into it directly from the browser.

+
+## Keyboard Shortcuts
+
+| Shortcut | Action |
+|----------|--------|
+| `Ctrl+K` / `Cmd+K` | Open command palette |
+| `Ctrl+S` / `Cmd+S` | Save editors |
+| `Escape` | Close command palette |
+| `Arrow keys` | Navigate command list |
+| `Enter` | Execute selected command |
+
+## Starting the Server
+
+```bash
+# Default: http://0.0.0.0:8000
+cf web
+
+# Custom port
+cf web --port 3000
+
+# Development mode with auto-reload
+cf web --reload
+
+# Bind to specific interface
+cf web --host 127.0.0.1
+```
+
+## Requirements
+
+The web UI requires additional dependencies:
+
+```bash
+# If installed via pip
+pip install compose-farm[web]
+
+# If installed via uv
+uv tool install 'compose-farm[web]'
+```
+
+## Architecture
+
+The web UI uses:
+
+- **FastAPI** - Backend API and WebSocket handling
+- **HTMX** - Dynamic page updates without full reloads
+- **DaisyUI + Tailwind** - Theming and styling
+- **Monaco Editor** - Code editing for compose/env files
+- **xterm.js** - Terminal emulation for logs and shell access
