"""A Claude Code CLI outside PATH is found by every core check, not only by the Anthropic adapter.

A backend started by a macOS LaunchAgent or spawned by Hermes Desktop inherits a bare PATH that
carries none of Claude Code's install prefixes (``~/.local/bin``, ``~/.claude/local``, ...).
``agent.anthropic_adapter`` probes those prefixes after PATH; ``_external_process_spec`` and
``run_oauth_setup_token`` asked PATH only, so a provider whose ``process_command`` is ``claude``
was reported missing ("Could not find the ... CLI command 'claude'") on a machine where the
adapter could run it. Reported against hermes-plugin-claude-subscription-directsdk#32.
