Problem
The VoyageAI instrumentation reads request data only from kwargs. The Voyage SDK documents embed(texts, model) and rerank(query, documents, model) as positional calls. With positional arguments, spans lose gen_ai.request.model and all prompt content (embed texts; rerank documents and query).

Fix
Bind the call's args and kwargs to the wrapped method's signature (inspect.signature(...).bind_partial) before reading request attributes. If binding fails, fall back to kwargs, so behaviour never gets worse.

Tests
Added tests/test_positional_args.py with embed and rerank cases. They stub the network layer (no API key or cassette needed). They fail on main and pass with this change. Full voyageai suite: 6 passed. Lint (ruff check): all checks passed.

Before / after (reproduction with a stubbed client, client.embed(["hello"], "voyage-3")):
Before: span had only gen_ai.operation.name='embeddings', gen_ai.system='voyageai', gen_ai.usage.input_tokens=7 — missing gen_ai.request.model, gen_ai.prompt.0.role, gen_ai.prompt.0.content.
After: gen_ai.request.model='voyage-3', gen_ai.prompt.0.role='user', gen_ai.prompt.0.content='[{"type": "text", "text": "hello"}]'.

Summary by CodeRabbit

• Bug Fixes
  • Voyage AI telemetry now captures model and input details correctly when embed and rerank arguments are passed positionally, for both synchronous and asynchronous calls.

Walkthrough

Voyage AI instrumentation now resolves positional and keyword arguments for synchronous and asynchronous calls. New tests check span attributes for positional embed and rerank calls.

Changes: Voyage AI argument capture

Layer / File(s)	Summary
Bind call arguments packages/opentelemetry-instrumentation-voyageai/opentelemetry/instrumentation/voyageai/utils.py	get_call_arguments binds positional and keyword arguments to the wrapped callable’s signature. If inspection or binding fails, it returns a copy of kwargs.
Use resolved arguments in wrappers packages/opentelemetry-instrumentation-voyageai/opentelemetry/instrumentation/voyageai/__init__.py, packages/opentelemetry-instrumentation-voyageai/tests/test_positional_args.py	Both wrappers use resolved arguments for request and input-content attributes. Tests check span attributes for positional embed and rerank calls.

Full details: Title check

Explanation

The title names the change: the VoyageAI instrumentation now captures span attributes for arguments passed positionally. The raw summary confirms that the change binds positional and keyword arguments through get_call_arguments, and the added tests cover embed and rerank called with positional arguments. The title names the fix and the affected component, and it matches the main change. It is a single, specific sentence with no vague terms.

Full details: Docstring Coverage

Explanation

Docstring coverage is 60.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 3 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
