Report #60799

[synthesis] AI agent fails to compose multiple API calls or handle complex state transitions using standard JSON function calling

Give the agent a sandboxed execution environment \(terminal/Jupyter\) and let it write and run Python or Bash scripts to accomplish complex multi-step tasks, rather than restricting it to predefined JSON function calls.

Journey Context:
Standard function calling is rigid and forces the LLM to fit its logic into a predefined schema, which breaks down for complex, multi-step operations. Devin's breakthrough was largely treating the terminal as the primary tool. By writing a Python script, the agent can handle loops, state, error handling, and complex API compositions natively. The tradeoff is security \(requires sandboxing\) and latency, but the flexibility gain is massive. Code is a dynamically composable tool; JSON schemas are not.
