Four patterns that use everything

Here are four architecture patterns we use in production. Each one combines multiple capabilities across multiple access methods. None of them would work with just one feature.

Pattern A: Morning Briefing

Trigger: Routine — runs at 7:00 AM daily

1. Check email for anything urgent (MCP)

2. Pull GitHub notifications and PR status (MCP)

3. Query the database for overnight metrics (Neon MCP)

4. Check analytics for traffic anomalies (skill)

5. Compile everything into a briefing

6. Send via Telegram (Channel)

Result: You wake up to a summary of everything that matters, compiled from four different systems, delivered to your phone before coffee.

Pattern B: Content Pipeline

Trigger: Routine or manual

1. Check Pocket Casts for new starred episodes (pocketcast skill)

2. Download and transcribe with speaker identification (transcriber skill)

3. Draft a newsletter from the transcript (newsletter skill)

4. Post a thread summary to social media (skill)

Result: A podcast you starred on your morning walk becomes a newsletter draft and social thread by the time you sit down.

Pattern C: Full Deploy

Trigger: Dispatch from phone

1. Run the test suite (Claude Code)

2. Create a Neon branch for staging data (Neon MCP)

3. Deploy to staging (Vercel MCP)

4. Run Lighthouse audit on staging (Chrome DevTools MCP)

5. If audit passes, deploy to production (Vercel MCP)

6. Confirm via Telegram (Channel)

Result: You kick off a full deploy from your phone at lunch. Tests, staging, performance audit, production — all automated. You get a Telegram message when it is live.

Pattern D: Incident Response

Trigger: Channel alert (monitoring webhook)

1. Check server status (MCP)

2. Query the database for recent errors (Neon MCP)

3. Pull deployment logs (Vercel MCP)

4. Capture the error state in browser (Chrome DevTools MCP)

5. Create a GitHub issue with all context (MCP)

6. Optionally: attempt a fix and deploy

Result: An alert fires at 2 AM. By the time you see it in the morning, Claude has already diagnosed the issue, gathered all the context, created an issue, and possibly fixed it.

Try This

Which of these four patterns maps closest to your work? For Cornwall Market, the Morning Briefing becomes the Monday Financial Summary — same structure, different data sources. The Incident Response becomes QuickBooks Sync Failure Handling — same flow, different trigger.

Pick one pattern. Map YOUR existing tools and capabilities onto it. What is the trigger? What data sources does it use? What skills does it apply? Where does the output go? You may already have most of the pieces from earlier chapters.
