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.

Tool Input Coercion for Numeric Parameters

Bash tool's timeout parameter and Grep tool's numeric parameters (-A, -B, -C, context, head_limit, offset) now accept string representations of numbers and coerce them to numeric types. This prevents errors when the model passes "5000" instead of 5000.

Evidence

Numeric string coercion wrapper (search for "oR(" in the Grep and Bash tool schema definitions)

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