Parse $ARGUMENTS to extract the repo and PR number:
REPO: and PR_NUMBER: (CI mode), use those values directly.https://github.com/), extract owner/repo and the PR number from it.gh repo view --json nameWithOwner -q .nameWithOwner.REPO: and PR_NUMBER:): post inline comments and summary to GitHub.Fetch PR details:

Read changed files to understand the full context around each change (not just the diff hunks).
Analyze the changes against these criteria:
| Area | What to check |
|---|---|
| TypeScript correctness | Proper typing, no unnecessary any, consistent use of strict mode, correct generics usage |
| Async error handling | Uncaught promise rejections, missing error callbacks, swallowed errors in streams. Double callbacks in try/catch blocks ā watch for try { cb(); } catch(err) { cb(err); } where an exception after the first cb() triggers a second call |
| Async/await migration | When code is migrated from callbacks to async/await, verify: no leftover callback or next params, no mixed callback + promise patterns, proper try/catch around awaited calls, errors are re-thrown or handled (not silently swallowed) |
| Stream handling | Backpressure, proper cleanup on error, no leaked file descriptors |
| Dependency pinning | Git-based deps (werelogs, sproxydclient, httpagent) must pin to a tag, not a branch |
| Logging | Proper use of werelogs, no console.log in production code, log levels match severity |
| Model compatibility | Changes to data models (ObjectMD, BucketInfo, etc.) must preserve backward compatibility with older mdModelVersion |
| Error handling | Proper use of ArsenalError, correct .is proxy checks, no swallowed errors |
| API contract | Breaking changes to exported interfaces in index.ts, renamed or removed public methods |
| Config changes | Backward compatibility, default values, constants changes |
| Security | Injection risks, auth bypass, improper input validation, OWASP-relevant issues |
| Breaking changes | Anything that changes public APIs or interfaces exported by this library |
| Test coverage | New logic should have corresponding tests, existing tests should not be removed without justification |
Deliver your review:
For each specific issue, post a comment on the exact file and line:
gh api -X POST -H "Accept: application/vnd.github+json" "repos/<owner/repo>/pulls/<number>/comments" -f body="Your comment<br><br>ā Claude Code" -f path="path/to/file" -F line=<line_number> -f side="RIGHT" -f commit_id="<headRefOid>"
The command must stay on a single bash line. Never use newlines in bash commands ā use <br> for line breaks in comment bodies. Never put <br> inside code blocks or suggestion blocks.
Each inline comment must:
Be short and direct ā say what's wrong, why it's wrong, and how to fix it in 1-3 sentences
No filler, no complex words, no long explanations
When the fix is a concrete line change (not architectural), include a GitHub suggestion block so the author can apply it in one click:
```suggestion
corrected-line-here
```
Only suggest when you can show the exact replacement. For architectural or design issues, just describe the problem. Example with a suggestion block:
gh api ... -f body=$'Missing the shared-guidelines update command.<br><br>\n```suggestion\n/plugin update shared-guidelines@scality-agent-hub\n/plugin update scality-skills@scality-agent-hub\n```\n<br><br>ā Claude Code' ...
When the comment contains a suggestion block, use $'...' quoting with \n for code fence boundaries. Escape single quotes as \' (e.g., don\'t)
End with: ā Claude Code
Use the line number from the new version of the file (the line number you'd see after the PR is merged), which corresponds to the line parameter in the GitHub API.
gh pr comment <number> --repo <owner/repo> --body "LGTM<br><br>Review by Claude Code"
The command must stay on a single bash line. Never use newlines in bash commands ā use <br> for line breaks in comment bodies.
Do not describe or summarize the PR. For each issue, state the problem on one line, then list one or more suggestions below it:
- <issue>
- <suggestion>
- <suggestion>
If no issues: just say "LGTM". End with: Review by Claude Code
Do NOT post anything to GitHub. Instead, output the review directly as text.
For each issue found, output:
**<file_path>:<line_number>** ā <what's wrong and how to fix it>
When the fix is a concrete line change, include a fenced code block showing the suggested replacement.
At the end, output a summary section listing all issues. If no issues: just say "LGTM".
