"""Post a review on a Gitea pull request.
Used by the GRM workflow to post structured PR reviews. The review body
is provided via --body and inline comments via a JSON file
(--comments-json) or stdin (--comments-stdin). This script is a thin
CLI wrapper around ``GiteaClient.create_review`` — the actual review
analysis is performed by the agent before invoking this tool.
Usage:
REPO_TOKEN=<token> python3 scripts/review_pr.py <pr_number> <repo> \
--event COMMENT \
--body "Review body text" \
--comments-json comments.json
The comments JSON file is a list of objects with keys:
- path: file path in the repo
- body: comment text
- new_position: line number in the new file (1-based)
- old_position: (optional) line number in the old file
Review focus areas (for the reviewer, not enforced by this script):
- Functional completeness
- Edge cases
- Technical excellence: architecture compliance, SRP, deduplication,
code smells, best practices, code quality, reusability, clean code,
readability, maintainability, extensibility
- Performance
- Security
- User experience
- Documentation completeness and relevance
