What this skill does


# Multi-Service Orchestration

## Overview

Multi-service management methodology adapted from the Everything Claude Code project. Handles service discovery, dependency resolution, PM2 management, cascade/parallel execution, and cross-service testing.

## Service Discovery
- Scan for service directories (packages/, services/, apps/)
- Parse package.json for dependencies and scripts
- Build dependency graph
- Detect package managers per service
- Determine topological execution order
- Flag circular dependencies

## Execution Modes

### Cascade Mode
- Sequential execution following dependency order
- Wait for health check before starting dependents
- Stop on failure with detailed error report
- Support partial cascade (skip healthy services)

### Parallel Mode
- Concurrent execution for independent services
- Optional worktree isolation per service
- Configurable concurrency limit
- Collect all results (continue on individual failures)

### Auto Mode (Default)
- Analyze dependency graph
- Use cascade for services with sequential dependencies
- Use parallel for independent service groups
- Hybrid: cascade between groups, parallel within groups

## PM2 Management
- Generate ecosystem.config.js from service manifest
- Configure per service: name, script, cwd, env, instances
- Start in topological order with health check gates
- Log rotation and restart policies
- Status monitoring: online, stopped, errored

## Cross-Service Testing
- API contract verification (request/response schemas)
- Event bus message flow testing
- Shared state consistency checks
- Authentication across service boundaries
- Circuit breaker behavior validation

## Health Monitoring
- Health check endpoint polling
- PM2 process status monitoring
- Resource usage tracking (CPU, memory)
- Log file error pattern detection
- Inter-service connectivity verification

## When to Use

- Multi-package monorepo development
- Microservice orchestration
- Full-stack application management
- CI/CD pipeline for multi-service deployments

## Agents Used

- `architect` (service discovery and dependency mapping)
- `build-resolver` (individual service builds)
- `e2e-runner` (cross-service integration testing)

generating-lwc-components

Included

Lightning Web Components with PICKLES methodology and 165-point scoring. Use this skill when the user creates or edits LWC components, builds wire service patterns, or writes Jest tests for LWC. TRIGGER when: user creates/edits LWC components, touches lwc/**/*.js, .html, .css, .js-meta.xml files, or asks about wire service, SLDS, or Jest LWC tests. DO NOT TRIGGER when: Apex classes (use generating-apex), Aura components, or Visualforce.

tanstack-query

Included

Manage server state in React with TanStack Query v5. Set up queries with useQuery, mutations with useMutation, configure QueryClient caching strategies, implement optimistic updates, and handle infinite scroll with useInfiniteQuery. Use when: setting up data fetching in React projects, migrating from v4 to v5, or fixing object syntax required errors, query callbacks removed issues, cacheTime renamed to gcTime, isPending vs isLoading confusion, keepPreviousData removed problems.

Included

Process documents with Nutrient DWS. Use when the user wants to generate PDFs from HTML or URLs, convert Office/images/PDFs, assemble or split packets, OCR scans, extract text/tables/key-value pairs, redact PII, watermark, sign, fill forms, optimize PDFs, or produce compliance outputs like PDF/A or PDF/UA. Triggers include convert to PDF, merge these PDFs, OCR this scan, extract tables, redact PII, sign this PDF, make this PDF/A, or linearize for web delivery.
