Vizra ADK is a retired Laravel package (final release v0.0.48) that provides a comprehensive framework for building AI agents with LLM orchestration, tool systems, memory, workflows, evaluations, tracing, and MCP integration. It is not a standalone application but a library designed to be installed into Laravel projects. The architecture follows Laravel package conventions: service providers, facades (Agent, Workflow), Eloquent models, Artisan commands, Livewire components, and database migrations. Key entry points include the Agent facade for running agents, the Workflow facade for orchestrating multi-agent workflows, and a set of CLI generators for scaffolding agents, tools, and evaluations. The system supports multiple LLM providers via Prism PHP, persistent memory (session, user, vector), tool chaining, sub-agent delegation, and an evaluation framework with LLM-as-a-Judge assertions. The codebase is well-structured with strong test coverage (Pest + Mockery), but the package is officially retired with no further development, leading to high technical drift as dependencies age out. Despite retirement, many components (e.g., ToolChain, VersionablePrompts, AgentVectorProxy, HasLogging) are self-contained and demonstrate reusable patterns suitable for extraction into new projects.
