What it tells you

• Read (38%) — Most sessions start by reading existing code or files
• Bash (28%) — A quarter of sessions open directly with shell commands
• Glob (17%) — File discovery is the third most common opener
• "Read→Read→Read" (13%) — The #1 opening pattern: understand before acting

The data reveals a clear preference for context-gathering before action — Claude Code reads first, then acts.
