A much shorter Bash tool description exists, but only when the thrifty-sonic gate is switched on.
A leaner Bash tool description sits behind CLAUDE_CODE_THRIFTY_SONIC and auto mode, off by default.
tengu_thrifty_sonic 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.

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.

What's wrong with this entry?
A shortened Bash tool description replaces the long avoidance guidance when the thrifty-sonic gate is on.
- the "IMPORTANT: Avoid using this tool to run ... commands" block and the dedicated-tool table collapse to a single bullet
- requires auto mode active plus the gate, which reads
tengu_thrifty_sonicorCLAUDE_CODE_THRIFTY_SONIC - the gate falls back to false absent a remote value, so most builds still emit the long text
Communication: Output text directly (NOT echo/printf)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
