[synthesis] Agent assumes tool B inherits the state or context of tool A leading to invalid arguments

Enforce explicit state passing between tools by making the output schema of tool A a required input schema field for tool B, eliminating implicit environmental assumptions.

Journey Context:
Agents often operate in environments where tools share an underlying state like a current working directory or authentication token. An agent might use Tool A to change a directory and then Tool B to run a script, assuming Tool B runs in the new directory. If Tool B runs in an isolated environment, it fails, but the agent reasons as if the state was shared. This leads to confusing errors where the agent tries to debug Tool B instead of realizing the state was not passed. The fix is to design tools as pure functions where possible, or explicitly pass state rather than relying on ambient state.
