## Discovery Commands


```bash
# List all hidden directories with sizes
du -sh .*/ 2>/dev/null | grep -v "^\./\.git"

# Find dead symlinks in hidden folders
find .agent-runtime -type l ! -exec test -e {} \; -print 2>/dev/null

# Count files in each hidden directory
for dir in .claude .agent-os .ai .common .specify; do
  if [ -d "$dir" ]; then
    count=$(find "$dir" -type f | wc -l)
    echo "$dir: $count files"
  fi
done
```
