Claude Code v2.1.232 ·

Bash tool description shape is decided once per process

The Bash tool's description length is decided once per process so it can't change mid-session.

What

Whether the Bash tool shows its shortened description is now worked out once and remembered for the life of the process, so it cannot change shape mid-session if the underlying value moves. The gate itself is unchanged: tengu_thrifty_sonic, off by default, overridable with the CLAUDE_CODE_THRIFTY_SONIC environment variable.

Feature flag
tengu_thrifty_sonic On for this account, and not off by default

The 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.

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 v2.1.232. It isn't a statement about your account. What a flag value here can and cannot tell you

What has happened since
Flag reading moved The flag server now returns on for tengu_thrifty_sonic, read as this account. 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.
