What
Two new input errors tell Claude what went wrong with a tool call (a request from Claude to use a tool):
- When the check that a tool was loaded fails, the tool does not run and Claude is told to call it once more.
- Browser tool inputs are now refused when a field holds JSON text in quotes or a
\uXXXX escape (a coded form of a character).
Why
Claude gets precise guidance on how to retry instead of a vague failure, which should mean fewer repeated broken browser calls.
