Names the domain (Claude Code sessions, learned skills) and describes the core action (extract reusable patterns, save as skills), but lacks comprehensive detail about what specific patterns are extracted or what 'learned skills' entails.

Describes what the skill does but completely lacks a 'Use when...' clause or any explicit trigger guidance. Per rubric guidelines, missing explicit trigger guidance caps completeness at 2, and this has no 'when' component at all.

Includes some relevant terms like 'patterns', 'Claude Code sessions', and 'skills', but misses common variations users might say such as 'learn from session', 'save workflow', 'remember how to', or 'create skill from'.

The concept of extracting patterns from sessions is somewhat specific, but 'reusable patterns' and 'skills' are broad terms that could overlap with other automation, templating, or learning-related skills.

The skill is reasonably efficient but includes some unnecessary sections like the comparison notes and research that could be in a separate file. The core content is well-organized but the v2 enhancement discussion adds bulk without immediate actionability.

Provides concrete, copy-paste ready JSON configurations for both config.json and settings.json. The hook setup command path is specific and the pattern types table gives clear, actionable categories.

The 3-step workflow (evaluate → detect → extract) is clear but lacks validation checkpoints. No guidance on what happens if extraction fails, how to verify learned skills are valid, or how to handle edge cases.

References external resources (Longform Guide, /learn command, v2 spec file) but the comparison notes section is inline when it should be in a separate RESEARCH.md or COMPARISON.md file. The main skill content is well-structured.
