Show HN: Budget Control in Claude Code Harness with Codex Handoff

Category: cli-tool

Tags: ai-agent, token-budget, cost-control, cli-tool, openai

Score: 6.0/10 (Innovation: 5, Technical: 6, Documentation: 6, Utility: 7)

This project introduces a token budget governor for AI coding agents like Claude Code and Codex, using a price-weighted proxy rather than raw token counting to manage subscription costs. It's interesting because it addresses a practical gap in cost control for heavy AI agent users, with a self-audited approach that reveals the difficulty of building accurate guardrails.

Target audience: backend devs, devops, ai engineers
