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.

Bash tool told that command output may not reach you

Bash Tool

Claude is told you may not see command output, so it should summarise results.

What

The Bash tool description now states plainly that command output is shown to the model but not reliably to the user, which should push the model to summarise results rather than assume you saw them.

Details
  • Added line: "- Command output is displayed to you, not reliably to the user."
  • It replaces one of the fragment lists previously spread into the assembled description.
Evidence

- Command output is displayed to you, not reliably to the user.

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