Detect code changes since last wiki update using git diff. Identifies added, modified, deleted, and renamed files to determine which documentation pages need updates.
Repo Wiki Detect Changes Skill
Detect code changes and determine documentation impact.
Purpose
This skill analyzes what changed in the codebase since the last wiki update:
- Files added, modified, deleted, or renamed
- Components affected by changes
- Documentation pages that need updates
- Citations that may have shifted
When to Use
Use this skill:
- After making code changes
- Before running
repo-wiki-update - To see what documentation will be affected
Step-by-Step Instructions
Step 1: Load Last Baseline Commit
LAST_COMMIT=$(uv run python -c "import json; print(json.load(open('.repo_wiki/state.json'))['last_run_commit'])")
CURRENT_COMMIT=$(git rev-parse HEAD)
Step 2: Compute Git Diff
git diff --name-status "$LAST_COMMIT".."$CURRENT_COMMIT" > .repo_wiki/changes.diff
Step 3: Parse Changes
Categorize into added, modified, deleted, renamed files.
Step 4: Map Files to Components
Determine which components are affected by changes.
Step 5: Identify Impacted Pages
Match changed files to existing documentation pages.
Step 6: Detect New/Deleted Modules
Check for components that need new pages or archiving.
Output Files
.repo_wiki/change_set.json- Structured change data.repo_wiki/logs/detection.log- Summary report
Success Criteria
- ✅ Change set created
- ✅ Impacted pages identified
- ✅ New modules detected
- ✅ Deleted modules identified
Next Steps
After detection:
- Update documentation: Read
