Open source / developer tools

Tools for the layer underneath the interface.

These projects explore the parts of software that are easy to miss in a product screenshot: where work runs, how agents coordinate, and how a useful experiment becomes a shareable tool.

Public project notes are kept concise and honest about what is available today.

Open-source project notes

Tools for the layer underneath the interface.

EfficiencyTool and Codex Boss Mode are public experiments in making computers and software workflows more intentional.

macOS utility

EfficiencyTool

A macOS utility that wraps a Bash script with Swift to assign selected process IDs to efficiency cores.

Built as a public experiment in making Apple Silicon resource behavior visible and controllable, with configurable rules for Chromium-based browsers and Electron apps.

Codex customization

Codex Boss Mode

An unofficial, experimental Codex customization that keeps the main agent focused on reasoning while making Codex workers available for execution.

The project explores a practical split between deciding what should happen and carrying out the work, while keeping the workflow explicit and inspectable.

01

Readable experiments

Each project starts with a concrete friction point and leaves a trail that another developer can inspect.

02

Close to the system

The work reaches below the polished surface when that is where the real behavior lives.

03

Shared with context

Repository links are paired with enough context to explain why the tool exists and what remains unfinished.
