"""Meme tool — injects a fake tool name into the response header.
Stargazer calls this tool with any arbitrary string, and that string
appears in the ``[`model` :: ... :: `tool_names`]`` header bracket as
though it were a real tool that was executed. The postprocessor picks
up the name from ``ctx.tools_executed`` and renders it verbatim.
Creative usage is encouraged: defensive obfuscation (``classified_op``,
``engage_countermeasures``), trolling (``lmao_imagine``,
``cope_and_seethe``), vibes (``caress_the_void``,
``weave_starlight``), or pure chaos (``ą̴̛̜̗b̸̡̖̱y̶̢̨̤s̷̰̜̓s``).
There are no rules. Be feral.

"""Inject a fake tool name into the response header's tool-call list.
The sole handler for the ``meme_tool`` tool. It does not perform any real
work or external action; its only effect is to append a caller-supplied
string to ``ctx.tools_executed`` so that, when the postprocessor assembles
the ``[`model` :: ... :: `tool_names`]`` bracket header, the fake name
appears alongside genuinely executed tools. This powers obfuscation, trolling,
and aesthetic flourishes in the header without any underlying capability.
Before appending it sanitizes the input with the module-level
``_HEADER_UNSAFE`` regex, stripping backticks, square brackets, and angle
brackets that would otherwise break the delimited header structure. The only
side effect is mutating the ``ctx.tools_executed`` list in place; if no
context (or no such attribute) is available it no-ops and says so. Because
``TOOL_NO_BACKGROUND`` is set the call runs inline so the name is present
before the header is built, and ``TOOL_ALLOW_REPEAT`` lets multiple calls in
one turn stack several names.
Discovered via the single-tool ``TOOL_NAME``/``run`` module format and bound
as the handler by ``tool_loader`` (``getattr(module, "run")``); dispatched by
the tool registry when the model calls ``meme_tool``, with no direct internal
callers.
Args:
name: The fake tool name to inject (any string; sanitized of
header-unsafe characters before use).
ctx: The tool context; its ``tools_executed`` list is appended to when
present.
Returns:
str: A short status message confirming the injected name, an error when
the name is empty or contained only header-unsafe characters, or a note
that no context was available to inject into.
