What
Several of Claude Code's tools, the actions Claude can take, now carry a short note telling the model when to use them:
The routines tool: prefer it over the local scheduler when a job must run on a schedule or event while Claude Code is closed.
WebFetch: use it to read a public web page; it cannot reach most private or signed-in pages, or localhost.
WebSearch: use it instead of memory alone for something recent or past the model's knowledge cutoff.
AskUserQuestion: use it instead of a plain-text question when stopping to wait for your answer.
The goal-proposal tool: not for one-off tasks.
These tools, along with the artifact comments tool and a few others, also gain a fixed identifier. The main descriptions of WebFetch, WebSearch and AskUserQuestion are unchanged in the capture taken under this release.
Why
The notes steer Claude toward the right tool, such as choosing a routine instead of a local timer for a job that has to run while Claude Code is closed.
