What
Claude Code has two new internal timing checkpoints, markers it records to measure performance:
- One when clearing of old tool results after the session sits idle is switched on. A tool result is the output Claude gets back from an action such as running a command. Failures of that clearing are logged under the same name.
- One the first time an action taken by computer use (Claude operating a desktop) is summarised.
Why
These markers point to two features being measured: clearing tool results after a session sits idle, and summarising computer-use actions.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
What controls whether those two features themselves are switched on is not known.
