Lists multiple specific concrete actions: execute skill via ccw cli Claude, evaluate quality via Gemini, apply improvements via Agent, and iterate until quality threshold or max iterations. The execute-evaluate-improve feedback loop is clearly described.

Clearly answers both 'what' (iterative skill tuning via execute-evaluate-improve feedback loop using specific tools) and 'when' (explicit triggers listed: 'skill iter tune', 'iterative skill tuning', 'tune skill').

Includes explicit trigger phrases users would say: 'skill iter tune', 'iterative skill tuning', 'tune skill'. These are natural terms a user would use when wanting this specific workflow.

Highly distinctive with a very specific niche: iterative skill tuning using a particular multi-agent pipeline (ccw cli Claude, Gemini, Agent). The trigger terms are unique and unlikely to conflict with other skills.

Extremely verbose at ~300+ lines. Contains extensive architecture diagrams, JavaScript pseudocode for orchestration logic, TodoWrite patterns, and coordinator checklists that could be dramatically condensed. Much of this (termination logic, error handling tables, data flow diagrams) is implementation detail that bloats the orchestrator document. The ASCII art diagrams, while visually appealing, consume significant tokens for information that could be stated in a few lines.

Provides concrete pseudocode for the iteration loop, termination logic, and preference collection, but none of it is truly executable — it's illustrative JavaScript that references undefined functions (AskUserQuestion, TaskCreate, TaskUpdate) and tools (ccw cli) without complete invocation syntax. The actual execution details are deferred to phase files that aren't provided, making the skill partially actionable but incomplete on its own.

The multi-step workflow is exceptionally well-sequenced with clear phase ordering (1→2→3→4→5), explicit termination conditions (threshold, max iterations, convergence, error limit), error recovery strategies per phase with retry/rollback, and a coordinator checklist. Validation checkpoints are built into the loop (Phase 3 evaluation before proceeding, snapshot before execute, convergence detection).

The skill correctly references phase files (phases/01-setup.md through phases/05-report.md) with a clear table and one-level-deep references, which is good structure. However, no bundle files are provided, so the referenced phase documents don't exist for evaluation. Additionally, the SKILL.md itself contains too much inline detail (full pseudocode for termination, TodoWrite patterns, error handling) that should live in the phase files, undermining the progressive disclosure principle.
