Jim Bennett d79183139a Add Arize and Phoenix LLM observability skills (#1204)
* Add 9 Arize LLM observability skills

Add skills for Arize AI platform covering trace export, instrumentation,
datasets, experiments, evaluators, AI provider integrations, annotations,
prompt optimization, and deep linking to the Arize UI.

* Add 3 Phoenix AI observability skills

Add skills for Phoenix (Arize open-source) covering CLI debugging,
LLM evaluation workflows, and OpenInference tracing/instrumentation.

* Ignoring intentional bad spelling

* Fix CI: remove .DS_Store from generated skills README and add codespell ignore

Remove .DS_Store artifact from winmd-api-search asset listing in generated
README.skills.md so it matches the CI Linux build output. Add queston to
codespell ignore list (intentional misspelling example in arize-dataset skill).

* Add arize-ax and phoenix plugins

Bundle the 9 Arize skills into an arize-ax plugin and the 3 Phoenix
skills into a phoenix plugin for easier installation as single packages.

* Fix skill folder structures to match source repos

Move arize supporting files from references/ to root level and rename
phoenix references/ to rules/ to exactly match the original source
repository folder structures.

Phoenix Tracing: Custom Metadata (Python)

Add custom attributes to spans for richer observability.

Install

pip install openinference-instrumentation

Session

from openinference.instrumentation import using_session

with using_session(session_id="my-session-id"):
    # Spans get: "session.id" = "my-session-id"
    ...

User

from openinference.instrumentation import using_user

with using_user("my-user-id"):
    # Spans get: "user.id" = "my-user-id"
    ...

Metadata

from openinference.instrumentation import using_metadata

with using_metadata({"key": "value", "experiment_id": "exp_123"}):
    # Spans get: "metadata" = '{"key": "value", "experiment_id": "exp_123"}'
    ...

Tags

from openinference.instrumentation import using_tags

with using_tags(["tag_1", "tag_2"]):
    # Spans get: "tag.tags" = '["tag_1", "tag_2"]'
    ...

Combined (using_attributes)

from openinference.instrumentation import using_attributes

with using_attributes(
    session_id="my-session-id",
    user_id="my-user-id",
    metadata={"environment": "production"},
    tags=["prod", "v2"],
    prompt_template="Answer: {question}",
    prompt_template_version="v1.0",
    prompt_template_variables={"question": "What is Phoenix?"},
):
    # All attributes applied to spans in this context
    ...

On a Single Span

span.set_attribute("metadata", json.dumps({"key": "value"}))
span.set_attribute("user.id", "user_123")
span.set_attribute("session.id", "session_456")

As Decorators

All context managers can be used as decorators:

@using_session(session_id="my-session-id")
@using_user("my-user-id")
@using_metadata({"env": "prod"})
def my_function():
    ...
