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.

Claude Code v2.1.208

Monitor tool description adapts to interactive vs non-interactive context

What

The Monitor tool's guidance text now varies based on whether the session is interactive. In interactive sessions (where the user is present at a terminal), Claude is now told to use a foreground Bash until loop for single-notification "tell me when ready" cases. In non-interactive/background sessions, the previous run_in_background recommendation is kept.

Details
  • For single-notification use cases in interactive sessions: "run the command in the foreground with Bash, exiting when the condition is true"
  • For single-notification use cases in non-interactive sessions: "use Bash with run_in_background"
  • The "don't use unbounded command for a single notification" warning likewise adapts its phrasing to the context
Evidence

Monitor tool description function (search for "run the command in the foreground with Bash")

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