hermes-vcc-engine is in the Hermes plugin catalog, so your Hermes Agent can compact a long chat without asking the model to write the summary:
- on a local model, the wait after a compaction is about 9x shorter in the author's tests
- it keeps every command with its exit code, the errors and the files it touched
- every line links back to the original message, and Hermes still keeps the originals
- one config line turns it on, one line puts the stock compressor back
