Review Comment:
   **🟢 Low**: Without a concurrency group, rapid pushes to the same PR can 
trigger parallel runs that race when inspecting and updating labels. Adding a 
`concurrency` block keyed on the PR number (or run ID for manual dispatch) 
prevents race conditions and saves runner minutes.

Review Comment:
   **🟡 Medium**: Running 5 `gh label create` API calls unconditionally on every 
`opened`, `synchronize`, and `reopened` event across all PRs generates 5 
redundant HTTP requests per run (returning 422 Already Exists once the labels 
exist). In a busy repo like `apache/beam`, this adds unnecessary latency and 
consumes `GITHUB_TOKEN` API rate limits. Since the labels (`size/XS` through 
`size/XL`) only need to be created once, consider removing this block from the 
hot path (or only running it if `gh pr edit` fails due to a missing label).

Review Comment:
   **🟡 Medium**: Use `grep -Fxq` here as well to ensure exact full-line label 
matching.
   
   ```suggestion
             if ! echo "$EXISTING_LABELS" | grep -Fxq "$SIZE"; then
   ```

Review Comment:
   **🟡 Medium**: Use `grep -Fxq` instead of `grep -Fq` to match the full line. 
Without `-x`, `grep -Fq "size/S"` will match substrings (for example, if a 
label like `size/S-override` or `size/XL` vs `size/X` ever existed).
   
   ```suggestion
               if echo "$EXISTING_LABELS" | grep -Fxq "$L" && [ "$L" != "$SIZE" 
]; then
   ```
