Required prerequisites

• I have searched the Issue Tracker and Discussions that this hasn't already been reported. (+1 or comment there if it has.)
• Consider asking first in a Discussion.

Motivation

ScreenshotToolkit.read_image() currently calls self.agent.step(...) inside the tool implementation.
When this tool is invoked by the same agent, it creates a re-entrant step() call during tool execution and can corrupt
the tool-call message sequence.

This leads to request failures like:

400 Bad Request: An assistant message with 'tool_calls' must be followed by tool messages responding to each
'tool_call_id'...
