ln-781-build-verifier

Type: L3 Worker Category: 7XX Project Bootstrap Parent: ln-780-bootstrap-verifier

Purpose

Detects project types, restores dependencies, executes builds, and verifies successful compilation.

Scope:

Auto-detect project types from file markers
Restore dependencies using appropriate package manager
Execute build commands for each project
Verify build artifacts exist

Out of Scope:

Running tests (handled by ln-782)
Container operations (handled by ln-783)

Scenario	Use This Skill
Called by ln-780 orchestrator	Yes
Standalone build verification	Yes
CI/CD pipeline build step	Yes
Test execution needed	No, use ln-782

Marker File	Project Type	Build System
package.json	Node.js/Frontend	npm/yarn/pnpm
*.csproj	.NET	dotnet
setup.py / pyproject.toml	Python	pip/poetry
go.mod	Go	go build
Cargo.toml	Rust	cargo
