For render/media/data agents, commands that create user-visible files MUST run
through ``await ctx.workspace_shell(...)`` or ``await ctx.workspace_python(...)``
and write under ``/workspace/outputs/...``. Do not use in-process
``asyncio.create_subprocess_exec`` for durable outputs; the agent container is
not workspace-mounted, so files created in ``/tmp`` or the image filesystem can
vanish after the request. Commands must still be bounded with timeouts and broad
exception handling, and failures must return structured JSON instead of
crashing the worker. Use ``render: bool = False`` by default and expose every
public skill argument with concrete type hints so the live ``input_schema``
contains the full call surface. If a render command returns nonzero after
emitting a usable file, preserve the file under ``/workspace/outputs/...`` and
include the command failure as a warning instead of dropping the result.

For Manim presentation agents specifically, generate a stable PDF fallback
that does not require Manim rendering. If HTML/video rendering is requested,
