+## Common: Discord Notification
+
+After mutating commands (claim, post, done), send a notification to the
+community Discord via the Wasteland bot. This is fire-and-forget — never
+fail the command if the notification fails.
+
+The bot URL is stored in the wasteland config or defaults to the community
+instance. Read it from config:
+
+```bash
+BOT_URL=$(cat ~/.hop/config.json | grep -o '"bot_url": *"[^"]*"' | head -1 | cut -d'"' -f4)
+BOT_URL=${BOT_URL:-https://wasteland-bot.hop.dev}
+```
+
+If no bot_url in config, use the default community bot. POST to `/notify`:
+
+```bash
+curl -s -X POST "$BOT_URL/notify" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "handle": "USER_HANDLE",
+    "event": "EVENT_TYPE",
+    "title": "ITEM_TITLE",
+    "id": "ITEM_ID"
+  }'
+```
+
+Event types and optional fields:
+- `posted` — new wanted item. Add `"effort": "EFFORT_LEVEL"`
+- `claimed` — task claimed
+- `completed` — completion submitted. Add `"evidence": "EVIDENCE_TEXT"`
+- `validated` — stamp issued
+
+The bot verifies the handle is a registered rig before posting.
+If the POST fails, log a warning and continue — never block the user.

+## Command: setup-discord
+
+Configure the Wasteland Discord bot URL. By default, notifications go to
+the community bot. Use this command to point to a custom bot instance.
+
+**Args**: none
+
+### Step 1: Ask for Bot URL
+
+Ask the user if they want to configure a custom bot URL, or use the
+default community bot (`https://wasteland-bot.hop.dev`).
+
+If they want a custom URL, ask for it.
+
+### Step 2: Test Connection
+
+```bash
+curl -s "$BOT_URL/health"
+```
+
+If the health check returns `{"ok": true}`, the bot is reachable.
+
+### Step 3: Save to Config
+
+Read `~/.hop/config.json`, add or update the `bot_url` field:
+
+```bash
+# Use jq or manual JSON edit to add bot_url to config
+```

+  Notifications will fire on:
+    /wasteland post   — new wanted items
+    /wasteland claim  — task claims
+    /wasteland done   — completion submissions
+```
+
+If it fails, tell the user to check the URL and verify the bot is running.
