📝 WalkthroughWalkthroughThe review-thread GraphQL examples update shell syntax, cursor initialization, nullable cursor validation, and outer and nested pagination loops. ChangesReview-thread pagination
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to This update changes shared audit guidance, but the current examples contain shell syntax errors and pagination logic that can duplicate data or repeatedly issue requests. The PR is not merge-ready until these bounded correctness and resource-use issues are fixed or explicitly accepted. Possibly related PRs

When a consumer executes this advertised block with /bin/sh, it fails immediately at args=( because arrays, [[ ... ]], args+=, and here-strings are Bash-only. Retain the bash fence or rewrite the loop using POSIX shell syntax so the required guardian workflow remains executable.

For a thread with more than 100 comments, the outer query has already returned the first page and its comments.pageInfo.endCursor; resetting cursor here makes the nested loop fetch that first page again before continuing. This duplicates up to 100 comments in the audit evidence and can cause the same feedback to be processed twice, so initialize this from the outer comments cursor as before.

When GitHub returns hasNextPage=true with the same nonempty endCursor as the preceding response, assigning it directly here discards the previous value and the loop repeats the identical request forever; the nested-comments loop now has the same regression. Preserve the previous cursor and fail when the next cursor is unchanged so a malformed or stale response becomes a reported blocker rather than hanging the required guardian audit.

- Line 17: Update both GraphQL audit loops to use Bash syntax, replace
angle-bracket placeholders in query and reply paths with shell-safe variables or
quoted values, initialize nested comment pagination after comments returned by
reviewThreads to avoid duplicates, and reject repeated non-empty endCursor
values so pagination always makes progress.

Make the audit examples executable and preserve cursor progress.
- Mark both GraphQL loops as
bash; they use arrays,[[ ... ]],+=, and here-strings. - Replace unquoted angle-bracket placeholders with shell-safe variables or quoted values.
<pr>and<number>are parsed as redirections, and the reply path has the same issue. - Start nested comment pagination after the comments already returned by
reviewThreads, or avoid emitting those comments twice. - Reject a repeated non-empty
endCursor; the current guard can loop indefinitely.
