Tool search can now refresh MCP clients and retry selection/search when matching tools may still be arriving from connecting servers.
- When enabled, direct
select:<tool_name>can retry after an MCP refresh. - Keyword searches can also refresh before declaring that no tools match.
- Claude receives clearer guidance that connecting MCP servers may expose tools shortly.
- This behavior is gated by
tengu_ashen_kelp.
Deferred tool refresh behavior (search for "ToolSearchTool: partial select after MCP refresh" and "tengu_ashen_kelp")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
tengu_ashen_kelp On for this account, and not off by defaultThe flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.
This account: on · anonymous baseline: on · compiled default in v2.1.128: no gate table built for this version
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 v2.1.128. It isn't a statement about your account. What a flag value here can and cannot tell you
A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
