Codex plugins for professional work
AI has the power. Codex provides the control.
Mparanza builds Codex plugins. Each gives Codex a specialist way of working for professional tasks.
The harness changes what AI can do.
AI provides the capabilities. Codex puts them in a working environment that can use files, run tools, follow instructions and create outputs. That harness is what we mean by control.
-
Power
The model reasons, analyzes and creates.
-
Control
Codex connects those capabilities to the files, tools and context of the task.
-
Professional use
A Codex plugin defines the specialist method and expected outputs.
Open by design.
Vera and Clara are open-source Codex plugins. You can inspect the methods, controls, and code before using them—and adapt them to your work.
Free by design.
Vera and Clara are free to install and use. We welcome contributions to their development. Mparanza charges for consulting, implementation, and hosted services.
Secure by design.
You do not have to trust us with your work. We do not receive it.
In local workflows, Vera and Clara run inside your existing Codex environment. Your prompts, files, and outputs do not pass through Mparanza.
