+# Phase 2: Docker Integration - Context
+
+**Gathered:** 2026-01-29
+**Status:** Ready for planning
+
+<domain>
+## Phase Boundary
+
+Connect n8n to Docker and return container information to Telegram. Users can query container status by name or view summaries. Container actions (start/stop/restart) are Phase 3.
+
+</domain>
+
+<decisions>
+## Implementation Decisions
+
+### Container Identification
+- Fuzzy matching for container names — "plex" matches "plex-server"
+- Case-insensitive matching — "Plex", "plex", "PLEX" all work
+- Strip common prefixes like "linuxserver-" before matching
+- When multiple containers match, list all matches and ask user to clarify
+
+### Query Patterns
+- Default "status" (no container name) shows running containers only
+- Support filtered queries: "show stopped containers", "what's unhealthy"
+- For many containers: summarize first ("25 running, 3 stopped"), then offer to list
+- When listing many, paginate results
+- Conversation context tracking deferred to Phase 4 (Claude API handles NLU)
+
+### Connection Approach
+- Clear error message on Docker connection failure: "Can't reach Docker — check if n8n has socket access"
+- No silent retries — fail fast with helpful message
+
+### Status Response Format
+- Emoji + text format: "✅ plex-server: Running (2 days)"
+- Single container check shows: name, state, uptime, health status, resource usage
+- Summary view info density left to Claude's discretion
+
+### Claude's Discretion
+- Docker connection method (socket mount vs TCP API)
+- Whether to use helper container or direct n8n calls
+- Emoji mapping for container states
+- Info density in summary/list views

+## Specific Ideas
+
+No specific requirements — open to standard approaches that work well on Unraid.

+## Deferred Ideas
+
+None — discussion stayed within phase scope.
