Git Investigate Skill

Trigger

  • •Keywords: code history, git blame, track changes, who wrote this, when was it changed, root cause, code archaeology

When NOT to Use

  • •Code review (use codex-review)
  • •Feature development (use feature-dev)
  • •Just want to read code (use Read directly)

Command

bash
/git-investigate src/service/xxx.ts:123      # Specific line
/git-investigate processToken                 # Function name
/git-investigate "error message"              # Keyword

Workflow

code
Locate code -> git blame -> find commit -> trace history -> analyze changes -> report

Investigation Framework

QuestionMethod
Who wrote it?git blame
When was it changed?git log --follow
Why was it changed?commit message + PR
What was missed?git diff compare original vs problematic version

Common Patterns

PatternSymptomRoot Cause
Type removedEnum value deletedAssumed no longer needed
Condition simplifiedIf conditions reducedMissed during refactoring
RenamePartially unchangedIncomplete search-and-replace
Boundary ignoredOnly handles main flowEdge cases not considered

Verification

  • •Report includes: investigation target, author info, timeline, original vs problematic code
  • •Root cause has clear analysis
  • •Fix recommendation is specific and actionable

Examples

code
Input: Who changed this line of code?
Action: git blame -> find commit -> trace PR -> output report
code
Input: When was this bug introduced?
Action: git log -p -S -> locate introduction point -> analyze cause -> output report
