Backend Developer Orchestrator

Coordinates two specialized backend sub-skills for systems-level and enterprise web development.

Purpose

Routes backend tasks to appropriate sub-skill based on language and context.

Context Discovery

Auto-Investigation

Detect backend stack from project:

Signal	How to Check	What It Tells Us
`go.mod`	`Glob("**/go.mod")`	Go project → :systems
`Cargo.toml`	`Glob("**/Cargo.toml")`	Rust project → :systems
`pom.xml`	`Glob("**/pom.xml")`	Java Maven → :enterprise
`build.gradle`	`Glob("*/build.gradle")`	Java Gradle → :enterprise
`*.csproj`	`Glob("*/.csproj")`	C# .NET → :enterprise
`composer.json`	`Glob("**/composer.json")`	PHP → :enterprise
`Gemfile`	`Glob("**/Gemfile")`	Ruby → :enterprise
DB config	`Grep("postgres\|mysql\|mongodb", "*/")`	Database type

Discovery Questions

Q1: Backend Language (if not detected)

question: "What backend language are you using?"
header: "Language"
multiSelect: false
options:
  - label: "Go"
    description: "High-performance, concurrent services"
  - label: "Rust"
    description: "Memory-safe, systems programming"
  - label: "Java (Spring)"
    description: "Enterprise, Spring Boot"
  - label: "C# (.NET)"
    description: "Microsoft ecosystem"
  - label: "PHP (Laravel)"
    description: "Web applications"
  - label: "Ruby (Rails)"
    description: "Rapid development"

Routing:

"Go" or "Rust" → Skill(faion-backend-systems)
"Java", "C#", "PHP", "Ruby" → Skill(faion-backend-enterprise)

Q2: Backend Task Type

question: "What type of backend work?"
header: "Task"
multiSelect: false
options:
  - label: "Build new service/API"
    description: "Create from scratch"
  - label: "Database design/optimization"
    description: "Schema, queries, performance"
  - label: "Add caching/queues"
    description: "Infrastructure patterns"
  - label: "Fix bugs/refactor"
    description: "Improve existing code"

Routing:

"Database" → database-design, sql-optimization
"Caching/queues" → caching-strategy, message-queues
Others → language-specific methodologies

Sub-Skills

Sub-skill	Focus	Methodologies
faion-backend-developer:systems	Go, Rust, databases, caching	22
faion-backend-developer:enterprise	Java, C#, PHP, Ruby frameworks	25

Routing Logic

Route to :systems for:

Go microservices, concurrency, HTTP handlers
Rust backend services, async, ownership
Database design, SQL optimization, NoSQL
Caching strategies, message queues
Low-level error handling

Route to :enterprise for:

Java Spring Boot, JPA, Hibernate
C# ASP.NET Core, Entity Framework
PHP Laravel, Eloquent, queues
Ruby Rails, ActiveRecord, Sidekiq
Enterprise patterns and testing

Integration

Invoked by parent skill faion-software-developer for backend work. Automatically selects appropriate sub-skill based on task context.
