Build Log: Kit #1 Produced by an Agent from Bootstrap Prompt with Evals

To validate the efficacy of our stack kit architecture, we conducted an end-to-end benchmark: could an autonomous coding agent build a complete enterprise administration portal solely from our bootstrap prompt and kit.yaml manifest?

The Bootstrap Test Setup

We initialized an empty workspace containing only our single-source rules and kit.yaml manifest. We assigned an autonomous Claude 3.5 Sonnet agent the bootstrap instruction to generate Kit #1: Laravel 12, Filament v3, PostgreSQL 16, and multi-tenant scoping.

# Execution command via evals runner
python evals/runner.py --kit laravel-filament-postgresql --benchmark full-bootstrap

Evaluation Results

Our benchmark runner evaluated 14 distinct criteria across four categories:

• Syntax & Formatting: Pint and PHP CS Fixer passed with 0 violations.
• Type Safety: Larastan Level 8 completed with 0 errors across 42 classes.
• Multi-Tenancy: Pest architecture tests verified that every Filament resource correctly applied TenantScope.
• Security Scans: Gitleaks and Semgrep reported 0 security vulnerabilities.
