Claude Code can defer some tools, holding back their full descriptions from Claude until they are needed. Two new remotely controlled switches can make certain tools appear early instead:
- one for tools that do not come from MCP servers
- one for connector tools marked to always load
Both fall back to off when Anthropic's servers send no value, and in readings taken before this release both read off for this site's account. The part of Claude Code that decides which tools to defer also now takes information about where the conversation starts and what is in view.
These switches change which tools are deferred, which changes what Claude is told at the start. With both off, behaviour stays as it was.

This account: off · anonymous baseline: off · compiled default in v2.1.321: not a boolean we can read
These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.
Read once, for one account on one subscription tier, against v2.1.321. It isn't a statement about your account. What a flag value here can and cannot tell you
