Tool Bay · ModelPlan Skill, Claude Code and Codex plugins, CLI and API

Bring recommended efforts and plan data into Claude Code, Codex and the terminal: an open-source Skill, plugins, the modelplan CLI, and a key-free read-only API and calendar feeds.

ModelPlan Skill

The main client, for any agent that supports Skills (Claude Code, Codex and others): which model, which effort, what one more step up costs, fitted to the quota left on your machine. GitHub

Claude Code plugin

/plugin marketplace add modelplan/modelplan
/plugin install modelplan@modelplan

Codex plugin

codex plugin marketplace add modelplan/modelplan
codex plugin add modelplan-codex@modelplan

modelplan CLI

curl -fsSL https://raw.githubusercontent.com/modelplan/modelplan/main/install.sh | sh

Open source (MIT), read-only, anonymous, no telemetry; quota is read on your machine only; it never switches your model or effort. github.com/modelplan/modelplan
