TIL : The agent reads 3x more than it writes

Top 3 tools used across 267 Claude Code sessions:

Bash   2700 calls
Read   1083 calls
Edit    545 calls

The agent spends more time running commands and reading files than modifying them. The Read/Edit ratio is 2:1. Add Bash (which mostly reads state — git status, tests, grep), and the actual read/write ratio is closer to 5:1.

A coding agent doesn’t code most of the time. It navigates, understands, diagnoses. Writing is the last step of a process that’s fundamentally about reading.
