fix(core): scope span export to our own tracer provider (#6954)
* fix(telemetry): stop exporting third-party spans to the collector

set_tracer() installed CrewAI's TracerProvider as the global one, so every
OTel-instrumented library in the host process - HTTP servers, Redis clients,
ORMs - resolved trace.get_tracer() to our provider and exported to CrewAI's
endpoint. A 20M-row sample of the telemetry table found 18,866 distinct
operation names under our serviceName; CrewAI emits 21.

The same wiring lost data in the other direction: when an application had
already installed its own provider, our spans were created by theirs and went
to their collector, so CrewAI received nothing from instrumented processes.

Spans are now created from the private provider in both packages. Deletes
_attach_common_attributes and its WeakSet/lock, whose multi-provider dedupe
guarded a state that can no longer occur.

* fix(telemetry): keep process context on crewai-core spans

Isolating each package to its own TracerProvider removed an accident the CLI
spans depended on: crewai_core.telemetry had no CommonAttributesSpanProcessor,
so its spans only ever carried coding_agent/runtime_context/project_id by
riding the global provider that crewai installed at import.

A differential capture of every span reaching the exporter showed 8 of 54 spans
losing those attributes - Feature Usage (cli_usage:*), Start Deployment,
Template Installed, Create Crew Deployment, Get Crew Logs, Remove Crew,
Deploy Signup Error and Flow Creation.

Moves the marker tables and the detect_* helpers to crewai_core.runtime_env and
the processor plus common_span_attributes() to crewai_core.telemetry, so both
implementations share one source of truth. crewai.telemetry.utils and
crewai.utilities.constants re-export the moved names, so their import paths are
unchanged.

Also fixes a gap that predates the isolation change: a CLI-only process never
imports crewai, so it never reported either attribute. It does now.

* fix(core): type test helpers and stop tests reaching the collector

mypy runs over lib/crewai-core/tests (the one test tree not excluded), so the
new test file needed full annotations and a narrowed span.attributes.

Also patches SafeOTLPSpanExporter before Telemetry is constructed and shuts the
provider down afterwards: __init__ wires a BatchSpanProcessor around the real
OTLP exporter, so each test was attempting a live export and leaving its batch
worker thread running.

Corrects the marker-precedence docstring, which named Cursor third when the
table checks it last so that assistants running inside its terminal are not
masked.

* style(core): use one import form per module in telemetry tests

Both test modules imported their telemetry module twice - once aliased for the
monkeypatch target and once via from-import for the names. Dropping the alias
in favour of monkeypatch's dotted-string target leaves a single import form and
removes the need to qualify every reference.

* docs(core): drop comments that restate the code

The TRACER_NAME constants were annotated with what their name and
set_tracer()'s docstring already say, and the test fixtures narrated
provider.shutdown() and the exporter patch at more length than either needed.

Keeps the ones carrying something the code cannot: the resource-attribute
ingestion quirk, why the marker tables moved packages, and the two ordering
traps the fixtures exist to avoid.

description: Understanding the telemetry data collected by CrewAI and how it contributes to the enhancement of the library.

## Telemetry
<Note>
By default, we collect no data that would be considered personal information under GDPR and other privacy regulations.
We do collect Tool's names and Agent's roles, so be advised not to include any personal information in the tool's names or the Agent's roles.
Because no personal information is collected, it's not necessary to worry about data residency.
When `share_crew` is enabled, additional data is collected which may contain personal information if included by the user.
Users should exercise caution when enabling this feature to ensure compliance with privacy regulations.
</Note>
CrewAI utilizes anonymous telemetry to gather usage statistics with the primary goal of enhancing the library.
Our focus is on improving and developing the features, integrations, and tools most utilized by our users.
It's pivotal to understand that by default, **NO personal data is collected** concerning prompts, task descriptions, agents' backstories or goals,
usage of tools, API calls, responses, any data processed by the agents, or secrets and environment variables.
When the `share_crew` feature is enabled, detailed data including task descriptions, agents' backstories or goals, and other specific attributes are collected
to provide deeper insights. This expanded data collection may include personal information if users have incorporated it into their crews or tasks.
Users should carefully consider the content of their crews and tasks before enabling `share_crew`.
Users can disable telemetry by setting the environment variable `CREWAI_DISABLE_TELEMETRY` to `true` or by setting `OTEL_SDK_DISABLED` to `true` (note that the latter disables all OpenTelemetry instrumentation globally).
### Examples:
```python
# Disable CrewAI telemetry only
os.environ['CREWAI_DISABLE_TELEMETRY'] = 'true'
# Disable all OpenTelemetry (including CrewAI)
os.environ['OTEL_SDK_DISABLED'] = 'true'
```
### Isolation from your own OpenTelemetry setup
CrewAI's telemetry runs on its own private `TracerProvider` and never registers
itself as the global one. This keeps the two directions separate:
- Spans from other instrumented libraries in your process — web frameworks,
database clients, HTTP clients — are never sent to CrewAI.
- CrewAI's telemetry spans are never sent to your observability backend, so they
will not appear in Langfuse, Braintrust, Phoenix, or any other collector you
configure.
Observability integrations are unaffected: they instrument CrewAI through their
own tracer provider, which is independent of the one described here.
### Data Explanation:
| Defaulted | Data | Reason and Specifics |
|:----------|:------------------------------------------|:----------------------------------------------------------------------------------------------------------------------------|
| Yes | CrewAI and Python Version | Tracks software versions. Example: CrewAI v1.2.3, Python 3.8.10. No personal data. |
| Yes | Crew Metadata | Includes: randomly generated key and ID, process type (e.g., 'sequential', 'parallel'), boolean flag for memory usage (true/false), count of tasks, count of agents. All non-personal. |
| Yes | Agent Data | Includes: randomly generated key and ID, role name (should not include personal info), boolean settings (verbose, delegation enabled, code execution allowed), max iterations, max RPM, max retry limit, LLM info (see LLM Attributes), list of tool names (should not include personal info). No personal data. |
| Yes | Task Metadata | Includes: randomly generated key and ID, boolean execution settings (async_execution, human_input), associated agent's role and key, list of tool names. All non-personal. |
| Yes | Tool Usage Statistics | Includes: tool name (should not include personal info), number of usage attempts (integer), LLM attributes used. No personal data. |
| Yes | Test Execution Data | Includes: crew's randomly generated key and ID, number of iterations, model name used, quality score (float), execution time (in seconds). All non-personal. |
| Yes | Task Lifecycle Data | Includes: creation and execution start/end times, crew and task identifiers. Stored as spans with timestamps. No personal data. |
| Yes | LLM Attributes | Includes: name, model_name, model, top_k, temperature, and class name of the LLM. All technical, non-personal data. |
| Yes | Crew Deployment attempt using crewAI CLI | Includes: The fact a deploy is being made and crew id, and if it's trying to pull logs, no other data. |
| Yes | Execution Environment | Includes: which AI coding assistant is running the process, if any (one of a fixed list such as `claude_code`, `codex`, `cursor`, or `unknown`), where the process runs (one of a fixed list such as `ci`, `container`, `serverless`, `interactive`), and the `project_id` from your `pyproject.toml` when one is configured. Detection reads only whether known environment variables are set, never their values. No personal data. |
| No | Agent's Expanded Data | Includes: goal description, backstory text, i18n prompt file identifier. Users should ensure no personal info is included in text fields. |
| No | Detailed Task Information | Includes: task description, expected output description, context references. Users should ensure no personal info is included in these fields. |
| No | Environment Information | Includes: platform, release, system, version, and CPU count. Example: 'Windows 10', 'x86_64'. No personal data. |
| No | Crew and Task Inputs and Outputs | Includes: input parameters and output results as non-identifiable data. Users should ensure no personal info is included. |
| No | Comprehensive Crew Execution Data | Includes: detailed logs of crew operations, all agents and tasks data, final output. All non-personal and technical in nature. |
<Note>
"No" in the "Defaulted" column indicates that this data is only collected when `share_crew` is set to `true`.
</Note>
### Opt-In Further Telemetry Sharing
Users can choose to share their complete telemetry data by enabling the `share_crew` attribute to `True` in their crew configurations.
Enabling `share_crew` results in the collection of detailed crew and task execution data, including `goal`, `backstory`, `context`, and `output` of tasks.
This enables a deeper insight into usage patterns.
<Warning>
If you enable `share_crew`, the collected data may include personal information if it has been incorporated into crew configurations, task descriptions, or outputs.
Users should carefully review their data and ensure compliance with GDPR and other applicable privacy regulations before enabling this feature.
