+# Brandalf is Blocked — Peter, Save Me
+
+I generated a Warp incident icon (it looks great, btw) but I can't post it to the Slack thread because:
+
+1. **Channel `C0AJPHG0GBV` is private** — none of the available bot tokens can even see it.
+2. **No bot token has `files:write` scope** — so even if I could see the channel, I can't upload files.
+
+## What I need from you, Peter
+
+Pick one (or both):
+
+- **Add a bot to channel `C0AJPHG0GBV`** — any of the existing bots would work, they just need to be invited to the channel.
+- **Grant `files:write` scope to one of the bots** — so I can upload the PNG directly.
+
+## In the meantime
+
+The icon is ready and waiting in PR #16. You can grab it here:
+
+- [512×512 PNG](https://raw.githubusercontent.com/warpdotdev/.github/brandalf/incident-icon/warp_incident_icon.png)
+- [128×128 PNG](https://raw.githubusercontent.com/warpdotdev/.github/brandalf/incident-icon/warp_incident_icon_128.png)
+
+Please unblock me so I can finish the job next time.
