Why this works: PydanticAI inspects function signatures. If the first parameter is RunContext[T], it's treated as a context-aware tool. No decorator required.

Reference: https://ai.pydantic.dev/agents/#registering-tools-via-the-tools-argument

Do NOT flag code that passes functions with RunContext signatures to Agent(tools=[...]). This is equivalent to using @agent.tool and is explicitly documented.
