Add /spawn-agent command:
- Spawns agents (codex, aider, claude) in isolated tmux sessions
- Git worktree support for parallel development
- Optional handover document passing (--with-handover)
- Isolated branches: agent/agent-{timestamp}
- Session metadata tracking in ~/.claude/agents/
- Monitoring pane with real-time output
Enhance /handover command:
- Add --agent-spawn mode for passing context to agents
- Two modes: standard (human) vs agent-spawn (task-focused)
- Saves to both primary and backup locations
- Programmatic timestamp generation
Add git-worktree-utils.sh (claude-code-4.5/utils/ and claude-code/utils/):
- create_agent_worktree: Creates isolated workspace
- cleanup_agent_worktree: Removes worktree and branch
- list_agent_worktrees: Shows all active worktrees
- merge_agent_work: Integrates agent branch
- CLI interface for manual management

Adds distinctive frontend design skill from anthropics/claude-code plugins marketplace. Provides guidance on avoiding generic AI aesthetics and creating production-grade, visually striking interfaces. Key principles: - Bold aesthetic direction (brutalist, maximalist, retro-futuristic, etc.) - Distinctive typography over generic fonts - Cohesive color systems with CSS variables - High-impact animations and motion - Unexpected layouts and composition - Atmospheric details (textures, gradients, patterns) Skill applies to both claude-code and claude-code-4.5 configurations.
Changed from documentation/pseudocode to executable implementation:
- Launches claude --dangerously-skip-permissions in tmux session
- Uses tmux send-keys to pass prompts to agent
- Optional --with-handover flag generates context (branch, commits, git status)
- Saves metadata to ~/.claude/agents/{session}.json
- Much simpler: 143 lines vs 245 lines of pseudocode
The agent now actually spawns and works independently in a tmux session.
Changed array length checks to be compatible with bash strict mode:
- From: ${#ARRAY[@]:-0} (doesn't work with arrays)
- To: [[ -v ARRAY[@] ]] && [ ${#ARRAY[@]} -gt 0 ]
Fixes "unbound variable" errors when checking empty arrays.
Added 4 new utility modules: - ui_interactions.py - Cookie banners, modals, overlays, stable waits - form_helpers.py - Smart form filling with field variation handling - supabase.py - Database operations for Supabase test setup/teardown - wait_strategies.py - Advanced waiting patterns (eliminates flaky tests) New complete example: - multi_step_registration.py - End-to-end registration flow Enhanced SKILL.md: - Comprehensive utility documentation with examples - Subagent usage guidance - Increased from 3,913 to 8,497 bytes (+117%) Impact: 2x-3x faster test development, 95%+ test reliability

Code Review
This is an impressive and comprehensive pull request that introduces tmux integration for persistent development environments. The new commands (/start-local, /start-ios, /start-android, /spawn-agent, /tmux-status) are well-designed and will significantly improve the development workflow. The documentation updates are thorough, and the new testing utilities are a fantastic addition. My review focuses on a few areas for improvement, mainly around consistency and robustness in the provided script examples to ensure they are as reliable as possible.

There are a couple of issues with the handover implementation in this script:
- Inconsistency with
handover.md: The documentation inhandover.mdstates that/spawn-agentshould call/handover --agent-spawnand save the result to a file. This script generates its own, simpler handover content instead. - Problematic
send-keys: The script usestmux send-keysto send the multi-line handover content to the agent. The newlines in the content will be interpreted asEnterpresses, causing each line of the markdown to be executed as a command, which is likely not the intended behavior.
It would be more robust to align this implementation with the documentation in handover.md by calling the /handover command and writing its output to a file in the agent's workspace.

There was a problem hiding this comment.
The example command for starting a server with log capture is missing redirection of stderr. This means that any error messages from the server won't be captured in the log file, making debugging more difficult. This also applies to other similar examples in this file (lines 274, 280, and 303).
To ensure all output is logged, stderr should be redirected to stdout before piping to tee.

The tee command is missing 2>&1, so stderr from the npm start command won't be captured in dev-server.log. This can make debugging difficult. The same issue exists on line 168 for the poltergeist command.

This example script makes extensive use of time.sleep(), which can lead to flaky and unreliable tests. The newly introduced wait_strategies.py utility provides much more robust waiting mechanisms like combined_wait() and smart_navigation_wait(). To better showcase the best practices of this skill, these explicit sleeps should be replaced with the new wait helpers where appropriate.
Add optional git worktree support for agent spawning to provide complete
isolation between concurrent agent sessions. Worktrees enable parallel
agent work without conflicts and make agent workspaces easily discoverable.
Changes:
- Add --with-worktree flag to spawn-agent command (opt-in)
- Generate descriptive worktree names: agent-{timestamp}-{task-slug}
Example: worktrees/agent-1763335443-implement-caching-layer
- Create isolated branches per agent: agent/agent-{timestamp}
- Detect transcrypt automatically (works transparently, no special setup)
- Update metadata to track worktree path and branch
New helper commands:
- /list-agent-worktrees - Show all active agent worktrees
- /cleanup-agent-worktree {id} - Remove worktree and branch (manual cleanup)
- /merge-agent-work {id} - Merge agent branch into current branch
- /attach-agent-worktree {id} - Attach to agent tmux session
Enhanced git-worktree-utils.sh:
- Support task slug in worktree directory names for discoverability
- Fix sourcing compatibility (only run CLI when executed directly)
- Redirect git output to stderr to avoid stdout pollution
- Support worktree lookup with optional task slug suffix
Benefits:
- Complete isolation between parallel agent sessions
- No conflicts between concurrent agent work
- Easy discovery via descriptive folder names
- Transcrypt encryption inherited automatically
- Clean separation of agent work from main workspace
Usage:
/spawn-agent "implement feature X" --with-worktree
/spawn-agent "review PR" --with-worktree --with-handover
/list-agent-worktrees
/cleanup-agent-worktree {timestamp}
Enhanced spawn-agent command with production-ready reliability improvements:
Initialization improvements:
- Add wait_for_claude_ready() function with intelligent polling
- 30-second timeout with proper error detection
- Verify Claude is actually ready before sending commands
- Session creation verification with graceful failure handling
- Debug logs saved to /tmp/spawn-agent-{session}-failure.log on failures
Input handling improvements:
- Line-by-line handover context sending (fixes multi-line issues)
- Literal mode (-l flag) for safe special character handling
- Proper newline handling in multi-line input
- Small delays between operations for UI stabilization
Verification and feedback:
- Task receipt verification (checks if Claude is processing)
- Error state detection in agent output
- Comprehensive status reporting with visual indicators
- Debug output display when errors are detected
Documentation additions:
- New troubleshooting section with common issues
- Debug log location and usage instructions
- Verification steps for failed spawns
- Enhanced notes explaining new reliability features
Benefits:
- No more race conditions from premature command sending
- Handles special characters safely (quotes, dollars, backticks)
- Multi-line handover context works correctly
- Clear failure messages with actionable debugging info
- Graceful cleanup on initialization failures
