fix(pr-review): use -F not -f for summary comment stdin body - #103
Merged
Conversation
gh api's @filename/@- stdin magic only works with -F (typed field), not -f (raw string). The prompt instructed -f body=@-, which set the comment body to the literal two characters "@-" instead of streaming the review text from stdin — reproduced live on baton-aws, baton-okta, baton-servicenow, baton-sql, and baton-google-workspace.

BODY_EOF could plausibly appear as a line in a generated review body, closing the heredoc early and feeding the remainder to the shell.
