Report #36122

[frontier] Static toolkits limiting agents to pre-defined capabilities, requiring human developers to add new tools for novel situations

Implement dynamic tool synthesis: when an agent encounters an unsolvable sub-task, it generates Python code to solve it, executes it in an E2B/Modal sandbox, and dynamically registers the function \(with auto-generated JSONSchema\) as a new tool for the remainder of the session. The agent effectively expands its own API surface during runtime.

Journey Context:
Pre-defined tools are brittle; agents need 'ad-hoc' tools like humans use disposable scripts. Static schemas break when data formats vary \(e.g., 'extract this weird PDF'\). Dynamic synthesis treats code generation as tool creation. The sandbox ensures safety; the registration makes the tool first-class for subsequent steps. This moves beyond 'code interpreter' which is one tool, to 'self-modifying agent' that persistently adds capabilities.
