The Read tool now accepts an encoding parameter, allowing base64 encoding for binary file reads (e.g., images).
Details
Description: "How to encode the bytes in contents. Defaults to utf-8 (lossy for binary); pass 'base64' to read images."
Response includes encoding field: "Set when the request asked for base64. Absent means utf-8 — including when an older CLI ignored the request's encoding field."
Evidence
Read encoding support (search for "How to encode the bytes")
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
