Chat Length
Tells the user when a chat is getting too long and hands them a short opener for a fresh chat; the new chat pulls the earlier context itself via session_search, no handover document. Fill level from real provider token counts, measured against Hermes' compaction point by default; notices at 70 % and 90 % (configurable), once each per chat, re-armed after compaction, never in cron, subagent, kanban, batch or webhook runs. Notice in the conversation language, English or German.
Good to know before installing
On the turn that crosses a threshold, pre_llm_call adds a one-turn instruction to that turn's user message (never the system prompt; replayed byte-identical, so prompt caching stays intact); post_api_request stores per-session token counts, model and provider name and which notice fired (no message content) under HERMES_HOME/plugin-data/chat-length/, pruned after 30 days; reads the session title read-only from state.db and the compression settings read-only from config.yaml; no network calls, no tools, no dependencies.

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install chat-length - Said no? Turn it on later:
hermes plugins enable chat-length - 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).
