While running aickyway, the server actually died at 3 AM once. Data gets lost, or deployments fail.

Let me show you how SuperClaude helps in these situations.

Crisis 1: The Database Crashed

9 AM, Slack notifications are flooding in. API responses are taking 30 seconds.

Step 1: Find the Problem

/sc:analyze --database --slow-queries

Found the issue. JOINing 1 million times on a table without indexes.

Step 2: Identify the Bottleneck

/sc:troubleshoot --bottleneck "posts table full scan"

The problem occurs when joining users and posts tables. There is no index on user_id.

Step 3: Fix Immediately

/sc:implement --hotfix "add indexes to foreign keys"

A migration file is generated. Adding indexes to user_id, category_id, and created_at.

Step 4: Apply Improvements

/sc:improve --query "optimize N+1 queries with eager loading"

ORM queries are modified. What used to query 100 times now processes in 1.

Step 5: Verify

/sc:test --load "simulate 1000 concurrent users"

Response time dropped from 30 seconds to 0.3 seconds. Crisis averted.

Crisis 2: Memory Keeps Growing

Production server memory usage is at 95%. It will die soon.

Step 1: Memory Profiling

/sc:analyze --memory --heap-snapshot

WebSocket connections are not being cleaned up. They remain on the server even after clients disconnect.

Step 2: Identify Root Cause

/sc:troubleshoot --memory-leak "WebSocket event listeners"

Event listeners are not being removed. When 1000 connections pile up, memory explodes.

Step 3: Fix

/sc:implement --fix "cleanup WebSocket connections on disconnect"

Code to remove listeners in the disconnect event is generated. Timers are also cleaned up.

Step 4: Add Monitoring

/sc:implement --monitoring "memory usage alerts"

Alerts come when memory exceeds 80%. Connection count is also tracked.

Step 5: Long-term Observation

/sc:test --stability "24-hour load test"

Running for 24 hours. Memory stays stable.

Crisis 3: Deployment Failed

CI/CD pipeline is red. Client demo is in 2 hours.

Step 1: Analyze Build Logs

/sc:troubleshoot --build-failure "Docker build errors"

Dependency version conflict. Issues from upgrading Node.js 18 to 20.

Step 2: Quick Fix

/sc:implement --fix "lock dependency versions"

package.json is modified. Exact versions are specified. package-lock.json is committed.

Step 3: Retry Deployment

/sc:build --docker --cache "optimize build time"

Using cache. Build time reduced from 10 minutes to 2 minutes.

Step 4: Safety Measures

/sc:implement --ci "dependency vulnerability check"

Adding security scan to CI. Risky packages are automatically blocked.

Deployment completed 30 minutes before the demo.

Team Project: Building a Streaming Platform

4 people building a video streaming platform. 2 week deadline.

Monday Morning: Kickoff Meeting

Team lead divides the project:

/sc:design --architecture "video streaming with CDN"

Architecture is laid out. Divided into upload server, transcoding server, CDN, and player.

Distributing tasks:

/sc:task --create --assign "video upload service (Alice)"
/sc:task --create --assign "transcoding pipeline (Bob)"
/sc:task --create --assign "player UI (Charlie)"
/sc:task --create --assign "CDN integration (David)"

Estimating time:

/sc:estimate --project "team of 4, 2 weeks"

Tight but doable. Setting 2 days buffer.

Monday Afternoon: Environment Setup

Setting up development environment:

/sc:implement --docker-compose "local development environment"

Everyone works in the same environment. PostgreSQL, Redis, MinIO running locally.

Tuesday-Thursday: Implementation

Alice builds upload:

/sc:implement --upload "multipart upload with resume"

Large files upload without interruption. Resumes even if network disconnects during upload.

Bob builds transcoding:

/sc:implement --ffmpeg "adaptive bitrate encoding"

Encoding to 1080p, 720p, 480p, 360p. Converting to HLS format.

Charlie builds player:

/sc:implement --player "video.js with quality selection"

Quality can be changed. 10-second skip and playback speed work.

David connects CDN:

/sc:implement --cdn "CloudFront with signed URLs"

Delivering videos quickly worldwide. Preventing unauthorized downloads.

Friday: Integration

Merging code from 4 people:

/sc:git --merge "resolve conflicts in API endpoints"

Resolving conflicts. API endpoint names overlapped.

Running integration tests:

/sc:test --e2e "upload, transcode, play workflow"

Testing the entire flow of uploading, encoding, and playing videos.

Weekend: Bug Fixing

Bugs flood in on Saturday. Large file uploads fail.

/sc:troubleshoot --upload "timeout on large files"

nginx timeout is 60 seconds. 5GB files cannot be uploaded within 60 seconds.

Changing settings:

/sc:implement --nginx "increase timeout and buffer size"

Increasing timeout to 10 minutes. Also increasing buffer size.

Week 2 Monday: Final Check

Testing performance:

/sc:test --load "100 concurrent streams"

Handles up to 100 concurrent connections. CPU usage at 70%.

Writing documentation:

/sc:document --api "streaming platform API reference"

API documentation is complete. Team members review.

Week 2 Wednesday: Deployment

Deploying to production:

/sc:build --production "with monitoring and logging"

Monitoring is attached. Collecting metrics with Prometheus. Creating dashboard with Grafana.

Deployment checklist:

/sc:document --checklist "production deployment"

Environment variables, database migration, backup, rollback plan are organized.

Success. Streaming platform is up in 2 weeks.

Advanced Mission: Designing a Fintech Platform

A financial platform handling payments, transfers, and loans. Security and stability are top priority.

Phase 1: Domain Design

Dividing financial domains:

/sc:design --ddd "fintech with account, payment, loan"

Divided into account management, payment processing, loan evaluation. Each is an independent service.

Defining events:

/sc:design --event-driven "financial transaction events"

Account creation, deposit, withdrawal, transfer, loan application events exist.

Phase 2: Account Service

Creating and managing accounts:

/sc:implement --service "account management with CQRS"

Separating Command and Query. Writes go to PostgreSQL, reads from Redis.

Tracking balance:

/sc:implement --ledger "double-entry bookkeeping"

Recording all transactions with double-entry bookkeeping. Balance never gets out of sync.

Phase 3: Payment Service

Processing payments:

/sc:implement --payment "distributed transaction with Saga"

Goes through multiple steps. Validation → Balance check → Deduction → Transfer → Completion. Rollback if it fails midway.

Integrating payment gateways:

/sc:implement --integration "Toss, KakaoPay, NaverPay"

Supporting 3 payment gateways. If one dies, use another.

Phase 4: Loan Service

Evaluating credit:

/sc:implement --scoring "credit scoring with ML"

Scoring credit with machine learning. Learning from past transaction history.

Approving loans:

/sc:implement --workflow "loan approval state machine"

Application → Review → Approval → Execution → Repayment. Validation at each step.

Phase 5: Infrastructure

Setting up API gateway:

/sc:implement --gateway "rate limiting and authentication"

Limiting request count. 100 per minute per user. Authenticating with JWT.

Building service mesh:

/sc:implement --service-mesh "mTLS with certificate rotation"

Encrypted communication between services. Certificates are automatically renewed.

Adding monitoring:

/sc:implement --observability "distributed tracing with Jaeger"

Tracking which services a request went through. Finding slow sections.

Phase 6: Security Enhancement

Encrypting financial data:

/sc:implement --encryption "field-level encryption for PII"

Encrypting social security numbers and account numbers. Keys are stored in AWS KMS.

Keeping audit logs:

/sc:implement --audit "immutable transaction logs"

Recording all transactions. Tracking who did what and when. Cannot be modified.

Enabling intrusion detection:

/sc:implement --security "anomaly detection with alerts"

Detecting unusual patterns. Blocks if 100 transfers at 3 AM.

Lessons Learned

Crisis Management

  • When problems occur, do not panic and start with /sc:troubleshoot
  • Collecting logs makes analysis easier
  • With monitoring, problems are found quickly

Team Collaboration

  • Dividing structure well at the beginning reduces conflicts
  • Defining API specs first enables concurrent work
  • The earlier you start integration testing, the better

Large-scale Systems

  • Dividing services small makes management easier
  • Event-based approach reduces coupling
  • Security must be considered from the start

Practical Tips

When Building Quickly

# Prototype fast
/sc:implement --prototype "MVP feature"

# Test only essentials
/sc:test --smoke "critical user paths"

When Building Properly

# Solid with TDD
/sc:implement --tdd "production-ready feature"

# Test thoroughly
/sc:test --comprehensive "all edge cases"

# Document in detail
/sc:document --detailed "API contracts and examples"

Learning Order

Week 1: Build a simple CRUD app Week 2: Build an API server Week 3: Add real-time features Week 4: Challenge microservices

It is okay to go slowly. What matters is building consistently.
