Score: 7.5/10 (Innovation: 7, Technical: 7, Documentation: 9, Utility: 7)

Tallyhook is a dependency-free Node.js CLI that parses local session logs from Claude Code and Codex CLI to calculate per-repo, per-team, and per-client AI usage costs, with optional markup for billing. It handles complex log parsing (deduplication, subagents, cache pricing) and offers an MCP server so agents can query their own costs. The project fills a real gap for consultancies and teams needing cost transparency and client billing for AI coding agents.

Target audience: consultancies, engineering managers, backend developers, devops
