+# Cockpit Examples E2E Verification Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking. This plan is SEQUENTIAL — each task requires a running server and Chrome browser verification that cannot be parallelized.
+
+**Goal:** Verify every cockpit capability example works end-to-end — Angular UI renders, Python backend responds, messages stream correctly, sidebar features display properly, and zero console errors. Fix any issues found in the chat/stream-resource libs.
+
+**Architecture:** For each example: start the serve script (Angular + Python), navigate Chrome to the port, send a test message, verify the response renders, check the capability-specific sidebar, screenshot for evidence, check console for errors. Kill servers between examples.
+
+**Tech Stack:** Chrome extension (MCP), `serve-example.ts` script, Angular dev server, LangGraph Python backend
+
+---
+
+## Prerequisites
+
+Before starting, ensure:
+1. `.env` symlinks exist for all Python backends (OPENAI_API_KEY)
+2. `uv` is installed for Python venv creation
+3. Chrome extension is connected
+
+```bash
+# Symlink .env for all Python backends
+for dir in cockpit/langgraph/*/python cockpit/deep-agents/*/python; do
+  ln -sf /Users/blove/repos/stream-resource/.env "$dir/.env"
+done
+```
+
+## Verification Protocol (same for each task)
+
+```
+1. Kill any running servers on relevant ports
+2. Start: npx tsx apps/cockpit/scripts/serve-example.ts --capability=<id>
+3. Wait for Angular (port) + Python (port+3823) to be ready
+4. Navigate Chrome to http://localhost:<port>
+5. Screenshot empty state
+6. Send test message via JS injection
+7. Wait for response (10-15s)
+8. Screenshot conversation
+9. Check console for errors
+10. Verify capability-specific feature (sidebar, interrupt panel, etc.)
+11. If issues found: fix in lib, rebuild, re-verify
+12. Kill servers
+```
+
+---
+

+| 5 | durable-execution | 4304 | 8129 | Step progress | "Write a short poem" |
+| 6 | subgraphs | 4305 | 8128 | Subagent sidebar | "Research quantum computing" |
+| 7 | time-travel | 4306 | 8127 | Checkpoint timeline | "Tell me a joke" |
+| 8 | deployment-runtime | 4307 | 8130 | Production config | "Hello" |
+| 9 | planning | 4310 | 8140 | Plan checklist | "Plan a birthday party" |
+| 10 | filesystem | 4311 | 8141 | File ops log | "Read the config file" |
+| 11 | da-subagents | 4312 | 8142 | Delegation tracker | "Analyze this topic" |
+| 12 | da-memory | 4313 | 8143 | Learned facts | "My favorite color is blue" |
+| 13 | skills | 4314 | 8144 | Skill invocations | "Calculate 15 * 7" |
+| 14 | sandboxes | 4315 | 8145 | Execution output | "Write Python code to print hello" |
