# NousResearch/hermes-agent · Warnings for plugins with missing env vars or no tools

- PR #58692: fix(plugins): warn on missing required env vars and zero-registration (salvage #2768)

Most members concern plugins (notably Hindsight) that silently register no tools when required environment variables such as HINDSIGHT_API_URL are missing, with proposed warnings for missing env vars, zero registrations, or unavailable memory providers. One member relates to loading $HERMES_HOME/.env from the systemd unit so plugins can see env vars, which is adjacent but a distinct angle.
