AI Coding Agent Token Cost Has No Native Visibility โ€” Devs Building Their Own CLI Monitors

Claude Code and Codex CLI ship with minimal built-in cost tracking. A community ecosystem of CLI monitors exploded: Claude-Code-Usage-Monitor hit 8.2k stars, CodeBurn (112 HN pts) finds 56% of spend is on idle turns, and the HN launch for the real-time monitor got 245 points. Devs are spending $1,400+/week blind.

Product Idea from this Signal

A CLI tool that reads Claude Code and Codex CLI session logs, quantifies token spend burned on idle turns, and shows per-session cost breakdowns devs can actually act on

9.1k โ–ฒ

Claude Code and Codex CLI ship with no native cross-session cost visibility. Devs spending $1,400+/week have zero built-in way to see where that money went. A community ecosystem filled the gap fast: Claude-Code-Usage-Monitor hit 8.2k GitHub stars and CodeBurn's HN launch (245 pts, 135 comments) found that 56% of spend goes to idle turns where the agent is waiting, retrying, or stalled. The existing tools surface totals but stop there. This CLI parses the raw session logs from both tools, classifies each turn as productive vs idle, ranks the sessions and workflows burning the most waste, and outputs a daily cost breakdown devs can use to cut their bill without changing their workflow.

Multiple monitors exist but none are first-party or cross-agent unified; 8+ separate tools with overlapping feature sets and no standard.
