Compare with cc-first (opening):
  First tool:  Read 38%, Bash 28%, Glob 17%
  Last tool:   Read 36%, Bash 34%, Grep 7%

What it tells you

• Read + Bash = 70% of session endings — verification and inspection dominate
• Bash→Bash→Bash (18.6%) is the #1 closing triple — sessions end with a burst of shell commands (tests, builds, checks)
• Glob drops from 17% (opener) to 0.8% (closer) — file discovery is an opening activity, not a closing one
• Grep rises from ~1% (opener) to 7% (closer) — targeted code search happens at the end, not the beginning
• Sessions that open and close with the same tool type suggest focused, single-purpose work

The cc-first comparison

| | First tool | Closing tool | |---|---|---| | Read | 38% | 36% | | Bash | 28% | 34% | | Glob | 17% | 0.8% | | Grep | ~1% | 7% |

Bash increases (+6%) from start to end — Claude Code shifts toward action and verification as sessions progress.
