agent-plugin-extra-message-policy

OpenPack/AgentWheel package for the same extra message policy concept across agent runtimes.

• OpenClaw: installs the existing extra-message-policy OpenClaw plugin.
• Hermes: installs a Hermes Python plugin that hooks pre_gateway_dispatch for listen-only / allow / silent-ingest policy and pre_llm_call for bounded raw recall context.

AgentWheel

Built-in OpenClaw adapter supports plugins directly:

agentwheel install . --adapter openclaw --dry-run

AgentWheel 0.9.0's built-in Hermes adapter does not expose plugins; use the included adapter config until upstream adds it:

agentwheel install . --adapter-config adapters/hermes-with-plugins.jsonc --dry-run

OpenPack runtime selection is declared in openpack.json through runtimes.

Hermes config

Defaults are installed as settings/hermes-extra-message-policy.json into .hermes/settings.json by AgentWheel. The plugin also reads ~/.hermes/settings.json directly under extra_message_policy.

Default policy is conservative: enabled, respond allowed, no passive ingest sink unless configured.
