Multi Step JSON With Memory
===========================

Source: ``examples/agents/multi_step_json_with_memory.py``

Introduction
------------

Reflexion, Generative Agents, and MemGPT each emphasize that iterative performance improves when prior state
is persisted and reused rather than recomputed from scratch. This example adds memory reads/writes to JSON
tool-calling so multi-step behavior remains auditable across turns.

Technical Implementation
------------------------

1. Configure ``Tracer`` with JSONL + console output so each run emits machine-readable traces and lifecycle logs.
2. Build the runtime surface (public APIs only) and execute ``MultiStepAgent.run(...)`` with a fixed ``request_id``.
3. Configure and invoke ``Toolbox`` integrations (core/script/MCP/callable) before assembling the final payload.
4. Persist and query context via ``SQLiteMemoryStore`` to demonstrate memory-backed workflow behavior.
5. Print a compact JSON payload including ``trace_info`` for deterministic tests and docs examples.
