+  <name>Task 1: Configure n8n Container for Docker Access</name>
+  <action>
+    User must configure n8n container in Unraid with the following:
+
+    1. **Mount Docker socket:**
+       - Unraid Docker UI -> n8n container -> Edit
+       - Add path mapping: Container Path: `/var/run/docker.sock` -> Host Path: `/var/run/docker.sock`
+       - Access Mode: Read/Write
+
+    2. **Enable Execute Command node:**
+       - Add environment variable: `NODES_EXCLUDE=` (empty string)
+       - This re-enables the Execute Command node which is disabled by default in n8n 2.0+
+
+    3. **Install curl in n8n container:**
+       - After container restarts, run: `docker exec -u root n8n apk add curl`
+       - This adds curl to the Alpine-based n8n image
+
+    4. **Restart n8n container** to apply changes

+  <action>
+    Create a simple verification to confirm Docker socket access works.
+
+    The user should run this command on the Unraid server:
+    ```bash
+    docker exec n8n curl --unix-socket /var/run/docker.sock 'http://localhost/v1.53/containers/json?all=true'
+    ```
+
+    If successful, this returns JSON array of containers.
+
+    Common issues:
+    - "Permission denied": Socket permissions issue - may need to run n8n as root or adjust socket permissions
+    - "curl: not found": curl not installed - run `docker exec -u root n8n apk add curl`
+    - Empty response `[]`: Docker has no containers (unlikely on Unraid)
+
+    Document the verification command for user to run.
+  </action>
+  <verify>
+    User runs: `docker exec n8n curl --unix-socket /var/run/docker.sock 'http://localhost/v1.53/containers/json?all=true'`

+  <name>Task 1: Add Docker Query Branch to Workflow</name>
+  <files>n8n-workflow.json</files>
+  <action>
+    Extend the existing n8n workflow with Docker query capability.
+
+    **New nodes to add:**
+
+    1. **Switch Node** (after IF User Authenticated, replaces direct connection to Format Echo):
+       - Route based on message content
+       - Case 1: Message contains "status" OR starts with container-related keywords -> Docker Query branch
+       - Case 2: Default -> existing Echo branch (for now, will be replaced by Claude NLU in Phase 4)
+
+    2. **Execute Command Node** (Docker List):
+       - Command: `curl --unix-socket /var/run/docker.sock 'http://localhost/v1.53/containers/json?all=true'`
+       - This fetches all containers (running and stopped)
+
+    3. **Code Node** (Parse and Match):
+       - Parse JSON response from curl
+       - Extract container name from user message (simple: look for words that aren't "status", "show", "check", etc.)
+       - Implement fuzzy matching per CONTEXT.md:
+         - Case-insensitive
+         - Strip common prefixes (linuxserver-, binhex-)
+         - Substring match
+       - Handle cases:
+         - No container name -> return summary (count by state)
+         - Single match -> return that container's details
+         - Multiple matches -> return list and ask for clarification
+         - No matches -> return "not found" message
+
+    4. **Code Node** (Format Response):
+       - Format per CONTEXT.md:
+         - Emoji + text: "checkmark plex-server: Running (2 days)"
+         - State emoji mapping: running=checkmark, exited=X, paused=pause, restarting=arrows, dead=skull
+         - Summary shows counts: "25 running, 3 stopped"
+         - Single container shows: name, state, uptime, image
+       - Strip leading slash from container names
+       - Calculate uptime from Status field (already human-readable like "Up 2 days")
+
+    5. **Telegram Send** (reuse existing Send Echo node or create new for Docker responses)
+
+    **Connection changes:**
+    - IF User Authenticated -> Switch Node
+    - Switch Node case "docker" -> Execute Command -> Parse and Match -> Format Response -> Telegram Send
+    - Switch Node default -> Format Echo -> Send Echo (existing)
+
+    **Error handling:**
+    - If curl fails (non-zero exit), format error message: "Can't reach Docker - check if n8n has socket access"
+    - If JSON parse fails, format error message: "Unexpected Docker response"
+
+    **Important implementation notes from RESEARCH.md:**
+    - Container names have leading slash: use `.replace(/^\//, '')`
+    - Health status may not exist: use optional chaining `?.`
+    - Use simple substring matching first (no external library needed)
