          TODAY'S DATE: ${TODAY}

          STEP 1: Gather PR data
          Run these commands to gather PR information. ONLY include PRs created or updated TODAY (${TODAY}):

          # PRs created today
          gh pr list --repo ${{ github.repository }} --state all --search \"created:${TODAY}\" --json number,title,author,labels,createdAt,updatedAt,reviewDecision,isDraft,additions,deletions --limit 100

          # PRs with activity today (updated today)
          gh pr list --repo ${{ github.repository }} --state open --search \"updated:${TODAY}\" --json number,title,author,labels,createdAt,updatedAt,reviewDecision,isDraft,additions,deletions --limit 100



          STEP 2: For high-activity PRs, check comment counts
          For promising PRs, run:
          gh pr view [NUMBER] --repo ${{ github.repository }} --json comments --jq '[.comments[] | select(.author.login != \"copilot-pull-request-reviewer\" and .author.login != \"github-actions\")] | length'

          IMPORTANT: When counting comments/activity, EXCLUDE these bot accounts:
          - copilot-pull-request-reviewer
          - github-actions

          STEP 3: Identify what matters (ONLY from today's PRs)

          **Bug Fixes From Today:**
          - PRs with 'fix' or 'bug' in title created/updated today
          - Small bug fixes (< 100 lines changed) that are easy to review
          - Bug fixes from community contributors

          **High Activity Today:**
          - PRs with significant human comments today (excluding bots listed above)
          - PRs with back-and-forth discussion today

          **Quick Wins:**
          - Small PRs (< 50 lines) that are approved or nearly approved
          - PRs that just need a final review

          STEP 4: Generate the recap
          Create a structured recap:

          ===DISCORD_START===
          **Daily PR Recap - ${TODAY}**

          **New PRs Today**
          [PRs opened today - group by type: bug fixes, features, etc.]

          **Active PRs Today**
          [PRs with activity/updates today - significant discussion]

          **Quick Wins**
          [Small PRs ready to merge]
          ===DISCORD_END===

          STEP 5: Format for Discord
          - Use Discord markdown (**, __, etc.)
          - BE EXTREMELY CONCISE - surface what we might miss
          - Use hyperlinked PR numbers with suppressed embeds: [#1234](<https://github.com/${{ github.repository }}/pull/1234>)
          - Include PR author: [#1234](<url>) (@author)
          - For bug fixes, add brief description of what it fixes
          - Show line count for quick wins: \"(+15/-3 lines)\"
          - HARD LIMIT: Keep under 1800 characters total
          - Skip empty sections
          - Focus on PRs that need human eyes

          OUTPUT: Output ONLY the content between ===DISCORD_START=== and ===DISCORD_END=== markers. Include the markers so I can extract it." > /tmp/pr_recap_raw.txt

          # Extract only the Discord message between markers
          sed -n '/===DISCORD_START===/,/===DISCORD_END===/p' /tmp/pr_recap_raw.txt | grep -v '===DISCORD' > /tmp/pr_recap.txt

          echo "recap_file=/tmp/pr_recap.txt" >> $GITHUB_OUTPUT

        env:
