Advisor
A persistent second model reviews every agent turn. After each turn the plugin hands the transcript to the model you nominate as advisor and delivers its findings as advice in the same session: [NIT], [CONCERN] or [BLOCKER] notes, held back until a later review raises the same point again, so the primary agent is not interrupted by a one-off remark. It reviews, it does not act: the advisor never edits files, calls tools or changes session state, and only reads the turn transcript. This is the backend counterpart of MoA — one extra model, not a committee: the primary agent does the work and the advisor checks it. Port of pi-omplike-advisor (Petr Baudis / pasky), itself rooted in oh-my-pi (Can Boluk). Runs inside the plugin host with no dependencies beyond Hermes itself.
Good to know before installing
Once the plugin is enabled, every completed turn costs one extra completion through Hermes's ctx.llm to the advisor model (the primary agent's provider unless you allow a provider/model override under plugins.entries.advisor.llm), carrying the user message, the final reply, every tool call and tool result in the session so far (each clipped to 500 characters) and the contents of a WATCHDOG.md in Hermes's working directory if one exists; deliverable advice is queued into the CLI session as a user-role message, which starts or interrupts an agent turn; state is kept under $HERMES_HOME/advisor/ and reviews run on one background thread; no other network, files or credentials.

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install advisor - Said no? Turn it on later:
hermes plugins enable advisor - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
