Lists specific concrete actions: analyzing Git history, discovering 'logical coupling' (files that change together), and 'hotspots' (frequently modified complex modules). Also references a specific methodology source.

Clearly describes WHAT the skill does but completely lacks a 'Use when...' clause or any explicit trigger guidance for WHEN Claude should select this skill. Per rubric guidelines, missing explicit trigger guidance caps completeness at 2, and this has none at all.

Includes relevant terms like 'Git 历史', '逻辑耦合', '热点', but missing common variations users might say such as 'code analysis', 'technical debt', 'refactoring targets', or file extensions like '.git'.

Very distinct niche focusing specifically on Git history analysis for code coupling and hotspots using a named methodology. Unlikely to conflict with general code analysis or Git commit message skills.

The skill includes some unnecessary philosophical framing and quotes that don't add actionable value. The methodology attribution is repeated multiple times. However, the core content is reasonably focused on the task.

Provides quick-start commands and git commands, but references scripts (git_forensics.py, git_hotspots.py) without showing their content or how to create them. The actual analysis steps are conceptual rather than executable.

Clear three-step workflow with explicit sequencing. Includes validation guidance (check for shallow clone, filter noise, watch for renames). The strategy matrix provides clear decision criteria for prioritization.

Content is well-structured with clear sections, but references external scripts that don't exist or aren't linked. No references to additional documentation files for advanced topics. The skill is self-contained but could benefit from separating the methodology explanation from the practical guide.
