Names the domain (CLI workers, tmux panes) and the core action (spawn for parallel task execution), but doesn't list multiple specific concrete actions like managing workers, monitoring progress, or handling results.

Describes what it does (spawn CLI workers in tmux panes) but completely lacks a 'Use when...' clause or any explicit trigger guidance for when Claude should select this skill.

Includes strong natural keywords users would say: 'claude', 'codex', 'gemini', 'CLI', 'workers', 'tmux', 'panes', 'parallel'. These are specific tool names and concepts users would naturally mention.

Very distinct niche combining specific CLI tools (claude, codex, gemini), tmux panes, and parallel execution. Unlikely to conflict with other skills due to the specific combination of technologies.

The skill is reasonably efficient but includes some redundant explanations (e.g., the detailed tmux detection logic in Phase 0 could be condensed). The comparison table at the end and error reference add value but the workflow phases contain some verbose conditional explanations.

Provides fully executable bash commands throughout, concrete examples with real syntax, and copy-paste ready code blocks. The usage examples, CLI commands, and verification steps are all specific and actionable.

Excellent multi-phase workflow with clear sequencing (Phases 0-6), explicit validation checkpoints (verify prerequisites, validate input before decomposing, verify command execution via pane capture), and error recovery guidance in the error reference table.

Content is well-organized with clear sections and tables, but everything is inline in a single file. The error reference and comparison tables are helpful, but some content (like the detailed Phase 0 tmux detection logic) could potentially be split to a reference file for cleaner overview.
