Inline shell commands in a skill's instructions can now be handed to the model to run explicitly instead of executing silently

What

Skills are packaged instructions written in markdown, and some embed inline shell commands (written as !command or in fenced ! blocks) that run automatically. When the permission decision for one of these commands is 'ask' (meaning Claude Code would normally prompt before running it), or a deny that's tied to an async-agent reason, a new code path can replace the command with a placeholder and instead tell the model to run it explicitly, exactly as written, and use its output. This turns what used to be an invisible side effect into a visible, explicit step in the conversation.

Why

This gives more visibility and control over shell commands embedded in skills, so a command that needs permission or was previously denied doesn't just silently fail or run without the user noticing.

Feature flag
tengu_iterative_falcon Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.271: on

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.

tengu_glowing_orbit 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.
