Names the domain (attack trees, threat paths) and some actions (build, visualize, mapping, identifying), but lacks comprehensive concrete actions like specific tree construction methods, output formats, or analysis techniques.

Clearly answers both what ('Build comprehensive attack trees to visualize threat paths') and when ('Use when mapping attack scenarios, identifying defense gaps, or communicating security risks to stakeholders') with explicit trigger guidance.

Good coverage of natural terms: 'attack trees', 'threat paths', 'attack scenarios', 'defense gaps', 'security risks', 'stakeholders' - these are terms security professionals would naturally use when needing this capability.

Clear niche focused specifically on attack trees - distinct from general security analysis, threat modeling, or vulnerability assessment skills. The specific mention of 'attack trees' and 'threat paths' creates a well-defined scope.

The content is lean and efficient, avoiding unnecessary explanations of what attack trees are or basic security concepts. Every section serves a clear purpose without padding.

Instructions provide a clear process outline but lack concrete examples of attack tree notation, specific annotation formats, or sample decompositions. The guidance is directional rather than executable.

Steps are listed in logical sequence but lack validation checkpoints. No feedback loop for verifying tree completeness or correctness before sharing with stakeholders.

Clean structure with overview content in SKILL.md and clear reference to implementation-playbook.md for detailed patterns. One-level-deep reference is well-signaled.
