What it tells you

• Shell utils dominate (31%) — sleep, echo, export: orchestration overhead more than you'd think
• Inspect is 25% — Claude reads and searches more than it executes. cat, grep, ls are the real workhorses
• Execute is 15% — running actual code (python3, node) comes third
• Git is 8% — version control is a consistent part of every workflow
• Package management is 5% — dependency installs happen, but rarely
• Test is 1.5% — explicit test runs are rare in raw sessions
