"""GitHub Copilot ACP provider profile.
|
|
|
|
copilot-acp does not speak OpenAI-over-HTTP: it drives an external ACP
|
|
subprocess over stdio. The profile therefore supplies its own client through
|
|
:meth:`ProviderProfile.create_client` instead of letting the core build an
|
|
``openai.OpenAI``. That hook is the registration seam — this profile is its
|
|
in-tree consumer, and an out-of-tree ACP provider registered from
|
|
``~/.hermes/plugins/model-providers/`` or a pip entry point uses the exact same
|
|
three lines without touching core.
