adding crew ai instrumentation

[venkata-pavani]

Description

Description

What I changed	What this means
Added CrewAI LLM call instrumentation	CrewAI LLM calls now produce telemetry that follows the OpenTelemetry GenAI semantic conventions.
Added GenAI attributes	The telemetry includes available model, provider, request settings, messages, tool definitions, response details, token usage, and error information.
Added spans and metrics	The instrumentation emits inference spans, client duration metrics, and token usage metrics through opentelemetry-util-genai.
Added success and failure handling	Successful calls complete their telemetry, while failed calls record and re-raise the original error without changing CrewAI's behavior.
Disabled CrewAI native telemetry by default	This prevents two unrelated sets of telemetry from being emitted while this instrumentation is active.
Allowed users to retain CrewAI native telemetry	Users can set CREWAI_DISABLE_TELEMETRY=false. Existing values are preserved and restored correctly. ref: #308 (comment)
Added completion-hook support	Captured prompts and completions can be forwarded using the shared completion-hook mechanism.
Added tests	Tests cover completed calls, failed calls, content capture, completion hooks, semantic-convention attributes, and native telemetry configuration.
Updated documentation and examples	The README explains the new behavior and includes a custom completion-hook example.

Type of change

Please delete options that are not relevant.

• New feature (non-breaking change which adds functionality)
• This change requires a documentation update

How has this been tested?

Testing

Check	Result
Pre-commit hooks	✅ Passed
Ruff lint and formatting	✅ Passed
Pyright typecheck	✅ Passed — 0 errors
CrewAI oldest supported version	✅ Passed — 10 tests
CrewAI latest supported version	✅ Passed — 10 tests
Conformance test	⚠️ Blocked locally because the installed Weaver CLI does not recognize --advice-data; the CrewAI scenario did not run

Future PR

In follow-up PRs, I plan to add CrewAI workflow, agent, and tool instrumentation using the invoke_workflow, invoke_agent, and execute_tool GenAI semantic conventions, along with proper context propagation and streaming support.

Pull request overview

Adds first-pass OpenTelemetry GenAI instrumentation for CrewAI LLM inference by translating CrewAI LLM lifecycle events into opentelemetry-util-genai inference telemetry, along with unit + conformance scaffolding and docs/examples.

Changes:

• Introduces a CrewAIInferenceEventListener that maps CrewAI LLM events to TelemetryHandler.inference() invocations.
• Adds unit tests for inference event translation, completion hook wiring, and disabling CrewAI’s native telemetry while instrumented.
• Adds a CrewAI conformance scenario + tox wiring and expands the package README with configuration and completion hook docs.
