Update the current PR description to reflect the latest changes made in this session.

Steps

1. Get the current PR body and write to a temp file, stripping Windows line endings:

   gh pr view --json body --jq '.body' | tr -d '\r' | tee /tmp/pr-body.md > /dev/null
   

   NOTE: Use tee instead of > to avoid zsh noclobber errors when the file already exists. The >| operator also doesn't work in the Bash tool's eval context.

2. Gather context about recent changes:

   • Use the conversation context to understand what was changed and why
   • Get the diff since the PR was opened: git diff origin/main...HEAD
   • Review recent commits: git log origin/main...HEAD --format="%s"

3. Use the Edit tool to make incremental changes to the temp file:

   • Use Edit to make specific, targeted changes - do NOT rewrite the entire file
   • Keep the existing structure and sections
   • Update the Summary and Changes sections to reflect the latest work
   • Add any new testing steps if applicable
   • Preserve any existing context that is still relevant

4. Update the PR with the edited description:

   gh pr edit --body-file /tmp/pr-body.md
   

IMPORTANT: Use the context of the current conversation to inform the updates. The discussion, decisions, and work done in this session provide valuable context for explaining what changed and why.

IMPORTANT: Preserve the existing PR template structure. Only update the content within the sections, don't remove or restructure sections unless specifically asked.

CRITICAL: Always use the Edit tool to make changes to the PR description file. Never rewrite the entire file - make incremental edits so the user can see diffs.
