Source Intelligence

DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

The model is told when command sandboxing is switched off mid-session

Sandbox

Turning command sandboxing off mid-session now tells the model the earlier sandbox instructions no longer apply.

What

The sandbox description sent with each turn is re-rendered and compared with the last one in the transcript, so policy changes reach the model while the session is running. When sandboxing is turned off, the description goes empty and the model is told that the command sandbox has been disabled and the earlier instructions no longer apply.

Details
  • The description is produced only when the Bash tool is available and sandboxing is enabled locally; no remote flag is involved.
  • The disabled notice is a fixed sentence built around the Bash tool name.
  • The attachment type is stripped before token-count caching, as the agent listing delta already was.
Evidence

command sandbox has been disabled. Commands now run without sandbox restrictions; the earlier sandbox instructions no longer apply.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
