CloakWatch

How it works: CloakWatch quietly checks raid members' equipment while you're in Blackwing Lair, so you can see at a glance who's wearing the Onyxia Scale Cloak (the cape that protects against Shadowflame and Nefarian's Corruption of Blood mechanics — critical for Hardcore).

It shows a small movable panel listing everyone in the raid with a status icon next to their name:

• 🔴 Cloak off — not protected, call it out
• 🟢 Cloak on — good to go
• ⚪ Not yet checked — still verifying
• 🟡 Outdated — hasn't been re-checked in a while (they may have swapped gear)

It only activates inside Blackwing Lair while you're in a raid group, and only tracks players actually near you (the game doesn't let you check someone's gear from across the zone). It checks people gradually in the background — never scanned first, then stale results, then confirmed-off players get rechecked before confirmed-on ones — so it stays polite to the game's own rate limits instead of hammering everyone at once.
