chore(ci): add optimized PR size labeler and batch workflows by sripasg · Pull Request #27616 · google-gemini/gemini-cli

sripasg · 2026-06-01T17:04:49Z

Summary

Introduces two workflows to automatically categorize Pull Requests by size:

'PR Size Labeler' (.github/workflows/pr-size-labeler.yml) which runs on
PR events (opened, synchronized, reopened) and manual triggers.
'PR Size Labeler (Batch)' (.github/workflows/pr-size-labeler-batch-run.yml)
which retroactively labels existing PRs via manual triggers.

Details

The system consists of two GitHub Action workflows that operate completely
server-side using the GitHub API via the 'gh' CLI, removing the need to
locally checkout the repository.

PR Size Labeler (.github/workflows/pr-size-labeler.yml)
- Triggers: Automatically runs when a Pull Request is opened, synchronized
  (new commits pushed), or reopened. It can also be triggered manually via
  workflow_dispatch by providing an optional PR number.
- Label Synchronization: Inspects current PR changes and determines the
  correct size label based on total modifications (additions + deletions):
  - size/XS: < 10 lines (Green, #7ee081)
  - size/S: 10-49 lines (Yellow-green, #a6d49f)
  - size/M: 50-249 lines (Amber/Yellow, #f7d070)
  - size/L: 250-999 lines (Orange, #f48c06)
  - size/XL: >= 1000 lines (Red, #dc2f02)
- Execution Flow:
  - Dynamically creates any of the five size labels in the repository if they
    are not already present.
  - Fetches additions, deletions, changed files, and existing labels in a
    single GitHub API query.
  - Compares the calculated size to existing labels and executes a single
    atomic edit call only if a label change is required.
  - Locates any previous size comment left on the PR by the actions bot and
    updates it inline, leaving exactly one clean status comment in the thread.
PR Size Labeler (Batch) (.github/workflows/pr-size-labeler-batch-run.yml)
- Triggers: Triggered manually via workflow_dispatch to retroactively label
  historical pull requests.
- Inputs:
  - process_all: Boolean option to specify whether to check all PR states
    (open and closed) or open PRs only.
  - limit: Numerical limit to control the maximum number of PRs to query
    (defaults to 100).
- Execution Flow:
  - Ensures target labels exist in the repository.
  - Fetches the metadata (additions, deletions, and current labels) for all
    eligible PRs within the specified limit in a single consolidated request.
  - Iterates over the retrieved PR list, evaluates size categories locally
    in-memory, and executes updates only for PRs missing the correct size
    label.
