📝 Walkthrough

Walkthrough

Adds logging and restructures Sunday vs. non‑Sunday control flow in the reminder cron, aggregates and reports non‑404 errors while removing noisy logs in role‑sync, and removes the unused hackReminders import/schedule call from the cron index. (50 words)

Changes

Cohort / File(s)	Summary
Reminder Task apps/cron/src/crons/reminder.ts	Added runtime logging of totalEvents and per‑group details. Reworked Sunday vs non‑Sunday control flow: removed early return after Sunday handling and moved non‑Sunday date formatting and reminder sending into an else branch; final per‑prefix/event send loop remains.
Role‑Sync Task apps/cron/src/crons/role-sync.ts	Introduced errorCount and erroredUsers to accumulate non‑404 per‑user errors and report up to five usernames; removed two verbose permission change logs; final summary now includes error count and sample errored users.
Cron Index apps/cron/src/index.ts	Removed hackReminders from the import list and deleted its scheduled invocation; left preReminders and reminders imports/scheduling intact.

In `@apps/cron/src/crons/reminder.ts`:
- Around line 140-148: The code duplicates work by recalculating the total in a
new variable total_events; instead remove the total_events declaration and
accumulation loop and reuse the already-computed totalEvents (from lines where
totalEvents is calculated) when logging the final count, while keeping the
groupedPrefixes iteration only for printing group/event details (use
groupedPrefixes and event.name/event.name references as before and replace
console.log(`Found a total of ${total_events} events`) with console.log(`Found a
total of ${totalEvents} events`)).

37-37: Add explicit type annotation for erroredUsers.

Without an explicit type, TypeScript infers never[] (strict mode) or any[], which can cause type errors or bypasses type checking. Since you're storing user names (strings), annotate it explicitly:

✏️ Proposed fix

-    let erroredUsers = [];
+    let erroredUsers: string[] = [];

As per coding guidelines: "No TypeScript escape hatches: Flag usage of 'any' type... suggest... proper typing instead"

166-168: Consider wrapping webhook calls in try-catch to prevent crashes.

Per cron guidelines, "Discord webhook failures should not crash the service." Currently, if webhook.send() fails (network issue, rate limit, invalid webhook), the entire cron will throw and terminate.

🛡️ Example pattern for resilient webhook calls

try {
  await webhook.send({ content: `...` });
} catch (error) {
  console.error(`Failed to send webhook message:`, error);
  // Optionally continue or abort gracefully
}

As per coding guidelines: "Discord webhook failures should not crash the service"

21-23: Placeholder mention won't notify anyone — consider a TODO with issue tracking.

@WHOEVER_IS_DEV_LEAD_RN isn't a valid GitHub mention and won't alert anyone. If this needs manual re-enabling for hackathons, consider linking to an issue or adding a more actionable TODO:

✏️ Suggested improvement

-// Silencing for now, needs to be manually re-enabled for hacks `@WHOEVER_IS_DEV_LEAD_RN`
+// TODO(`#348`): Re-enable hackReminders before next hackathon - requires manual activation by Dev Lead
 // hackReminders.schedule();
