Code Review: internal: better weekly output

Tasks

• Read and analyze the workflow file changes
• Provide comprehensive code review feedback
• Add reproduction/testing instructions

Summary

This PR improves the weekly PR summary workflow by transitioning from a minimalistic output format to a categorized, structured format with better organization and readability. The changes enhance the presentation of merged PRs for Discord delivery.

What Changed

The workflow prompt was updated to generate a more structured weekly summary with:

• Categorization: PRs are now grouped into Features, Bug Fixes, and Other
• Cleaner formatting: Uses emoji indicators (📈, ✨, 🐛, 🔧) and bullet points
• Category counts: Displays PR counts in both overview and section headers
• Better organization: Sorts PRs by merge date within categories

---

Code Quality Review

✅ Strengths

1. Better User Experience: The categorized format is much easier to scan and understand compared to the flat list
2. Consistent Formatting: Uses proper markdown headers (####) and emoji indicators for visual separation
3. Smart Categorization Logic: Clear rules for categorizing PRs based on title prefixes and keywords
4. Character Limit Handling: Maintains the 6000 character limit with proper truncation strategy
5. Backward Compatible: No breaking changes to the workflow structure or webhook delivery

🔍 Observations & Suggestions

1. Categorization Logic Could Be More Robust

File: .github/workflows/weekly-pr-summary.yml:47-50

The current categorization relies on simple string matching:

- **Features**: PRs with titles starting with "feat:", "feature:", or containing "add", "implement", "new"
- **Bug Fixes**: PRs with titles starting with "fix:", "bug:", or containing "fix", "resolve", "patch"
- **Other**: All remaining PRs

Potential Issues:

• Keywords like "fix" in "prefix" or "add" in "address" could cause false matches
• No support for GitHub labels which might be more reliable

Suggestion: Consider word boundary matching to avoid partial matches, or leverage GitHub PR labels if they're consistently applied:

# Example with word boundaries
echo "$title" | grep -qiE '\b(add|implement|new)\b'

2. Date Range Display Missing

File: .github/workflows/weekly-pr-summary.yml:68-72

The old format included the date range in the output:

📊 Week of [Start Date] to [End Date]

The new format removes this. While it shows "Weekly overview", the specific date range would be helpful for archival purposes.

Suggestion: Consider adding the date range back:

#### 📈 Weekly overview (YYYY-MM-DD to YYYY-MM-DD)

3. Sorting Logic Changed

File: .github/workflows/weekly-pr-summary.yml:99

Old: Sort by importance (breaking changes > features > bugfixes > other)
New: Sort by merge date (most recent first) within each category

Impact: This is actually an improvement for most use cases, as recent PRs are more relevant. However, if there are critical breaking changes from earlier in the week, they might get buried.

Suggestion: Document this trade-off or consider a hybrid approach where breaking changes are always listed first within their category.

4. Title Truncation Note Could Be Clearer

File: .github/workflows/weekly-pr-summary.yml:97

The instruction "NEVER truncate PR titles - show full titles" is good, but the character limit enforcement (line 57-59) says to "truncate PR descriptions (NOT titles)".

Potential Issue: Very long PR titles could consume most of the 6000 character budget, leaving little room for descriptions.

Suggestion: Consider adding a soft maximum for titles (e.g., "Prefer titles under 100 chars, but never truncate them") to help Claude make better trade-offs.

5. Compact Formatting Trade-off

The new format uses more structural elements (headers, emojis, category names) which consume more characters than the minimalistic approach. This is a reasonable trade-off for better readability, but it means fewer PRs can fit in the 6000 character limit.

Calculation:

• Old format overhead: ~50 chars (header + total count)
• New format overhead: ~150 chars (overview section + 3 category headers)
• Net difference: ~100 chars, or ~1-2 fewer PRs

This is acceptable given the UX improvement.

Security Review

✅ No security concerns identified

• No new secrets or credentials introduced
• File handling remains safe (no commits to repo)
• Webhook delivery unchanged
• Uses existing approved tools only

---

Performance Considerations

✅ No performance concerns

• Categorization adds minimal overhead (simple string matching)
• Same number of API calls to GitHub
• Character counting happens in-memory
• Timeout remains appropriate at 30 minutes

---

Testing Instructions

How to verify this change:

Navigate to the GitHub Actions tab in the windmill-labs/windmill repository and manually trigger the "Weekly PR Summary" workflow using the workflow_dispatch option. After the workflow completes successfully, check the Discord channel where weekly summaries are posted (the channel configured to receive messages from the Windmill webhook endpoint). The summary should now display PRs organized into three emoji-labeled categories (Features ✨, Bug Fixes 🐛, and Other 🔧) with a statistics overview at the top showing total merged PRs and counts per category, instead of the previous flat list format. Each PR entry should show the full title, author username, and a brief description, sorted by merge date within its category, and if there are many PRs the summary should stay under 6000 characters by truncating descriptions and showing "and X more PRs" at the end.

---

Final Verdict

✅ Approve with minor suggestions

This is a solid improvement to the weekly PR summary output. The categorized format significantly enhances readability and makes it easier for the team to understand what happened during the week. The implementation is clean and maintains all existing functionality while adding value.

Recommended actions before merge:

1. Consider adding date range back to the output header
2. Test with a week that has 50+ PRs to ensure categorization and truncation work correctly
3. Optional: Enhance categorization with word boundary matching

The suggestions above are minor improvements and shouldn't block merging if the current format meets your needs.
