[satyadevai]

Closes #2140

---

Note

Emit tool JSON schemas on LLM_TOOLS for BeeAI chat spans and add examples, tests, and CI/deps updates.

• BeeAI Instrumentation:
  • Emit per-tool JSON schema on LLM_TOOLS.{index}.TOOL_JSON_SCHEMA using new helpers get_tool_parameters/get_tools in processors/chat.py (replaces prior tool-name list).
  • Include invocation parameters and message processing unchanged; tighten typings and safe JSON handling.
• Examples:
  • Add examples/beeai_ax.py (Arize OTEL) and examples/beeai_phoenix.py (OTLP -> Phoenix) demonstrating multi-agent tool handoffs and instrumentation setup.
• Tests:
  • Add tests/.../test_instrumentor.py asserting token/cost metrics, tool call attributes, and emitted tool schemas.
  • Add VCR cassettes for LLM and tool-call scenarios.
• Build/CI:
  • Update pyproject.toml test extras (pytest, pytest-asyncio, pytest-recording, vcrpy, duckduckgo extra, OTLP exporter).
  • Adjust tox.ini envlist for BeeAI to Python 3.11/3.13.
