    About Cache Tax

    Cache Tax uses function hooks to show cache-state estimates, flag a potentially costly cold send and optionally keep a session cache warm for a chosen period. Warming sends model requests and consumes tokens; it is not a promise of lower costs. It requires a one-hour main cache lifetime.

    • Shows an estimated rewrite cost before a cold send.
    • Starts and stops a bounded keep-warm period.
    • Reports cache status and recent warming activity.

    How to install

    Open the source documentation to check prerequisites and installation scope. Copy the commands below and run them one line at a time. Replace any example paths with the directory you intend to use.

    Terminal

    claude plugin marketplace add karanb192/claude-code-mods
claude plugin install cache-tax@claude-code-mods

    Requires Claude Code 2.1.287 or later. After installation, run /reload-plugins in the active session and check /plugin to confirm the mod loaded.

    Complete any authentication or settings steps documented by the maintainer, then reload the session and confirm the capability is available. Entries in the same repository may share a parent plugin installation.

    Getting started

    Check the maintainer’s cache-lifetime requirements first. Run /cache-tax to inspect status, /keepwarm 90m for a limited window, and /keepwarm off to stop. Keep Claude Code running and account for ping token usage.

    Before you use it

    Review the project instructions and requested tool access, then try a small task. This directory checks sources and setup notes; inclusion is not a code security audit.
