Show HN: PrismoDev – local CLI for finding token waste in Claude Code/Codex (github.com)

PrismoDev has launched a local CLI tool designed to help developers identify and reduce token waste while using AI coding agents like Claude Code and Codex. By running a single command, `npx getprismo doctor`, developers can diagnose issues related to token usage in their coding sessions, implement fixes, and visualize improvements, all without sending any data outside their local environment. This tool addresses common pitfalls that lead to excessive token consumption, such as unnecessary context from lockfiles, generated artifacts, and repeated file reads, which can inflate AI session costs. This development is significant for the AI/ML community as it provides a proactive solution for managing coding efficiency and costs associated with AI tools. The three main commands—`doctor`, `watch`, and `cc timeline`—serve to diagnose, monitor, and analyze coding sessions, respectively. Key functionalities include real-time context pressure monitoring and live guardrails that guide users during sessions to minimize token wastage. With detailed reports and actionable feedback, PrismoDev empowers developers to optimize their interactions with AI agents, ultimately leading to cost-effective coding practices and improved project outcomes.
