See what your coding agent sends. Mask what you can.
shim-cli is an open-source tool designed for developers working with AI coding assistants like Claude Code, Codex, and GitHub Copilot. It functions as a local proxy and hook, providing transparency into what data and code snippets are sent during AI interactions. One of its standout features is the ability to mask sensitive information, such as secrets and personal data, before they reach the AI model, enhancing privacy and security. Additionally, shim-cli offers a session monitoring feature with 'shim watch,' which displays what data was sent and the associated costs, giving developers better control and insight into their AI workflows. Its open-source nature, combined with the absence of telemetry and account requirements, makes it especially appealing for privacy-conscious developers who value transparency and local control.
