# This workflow performs AI-powered code review on PRs.
|
|
# It creates a Coder Task that uses AI to analyze PR changes,
|
|
# review code quality, identify issues, and post committable suggestions.
|
|
#
|
|
# The AI agent posts a single review with inline comments using GitHub's
|
|
# native suggestion syntax, allowing one-click commits of suggested changes.
|
|
#
|
|
# Triggers:
|
|
# - Label "code-review" added: Run review on demand
|
|
# - Workflow dispatch: Manual run with PR URL
|
|
#
|
|
# Note: This workflow requires access to secrets and will be skipped for:
|
|
# - Any PR where secrets are not available
|
|
# For these PRs, maintainers can manually trigger via workflow_dispatch.
