+"""Detect local-agent provider entries in a Plano config and warn the
+operator that the host is about to spawn a local CLI binary with the same
+filesystem, shell, and network capabilities as the user running planoai.
+
+Local-agent providers (e.g. ``claude-cli``) are an entirely different
+trust class from stateless network LLM providers (``openai``,
+``anthropic``, ``gemini``, ...): the bridge runs inside brightstaff and
+shells out to a local binary for every request, so a misconfigured
+production deployment would expose the host to whatever the spawned
+agent can do — which, for tools like Claude Code, is "anything the
+operator can do at the shell".
+
+This module is intentionally additive and side-effect free until the
+caller invokes :func:`maybe_warn_local_agent_providers`. The set of
+known local-agent provider interfaces lives in
+:data:`LOCAL_AGENT_PROVIDER_INTERFACES`; adding a future entry (codex,
+chatgpt-cli, opencode, hermes, ...) is a one-line change.
