4 use cases

  • Cut per-turn model spend in a Hermes agent

    Let Jev pick a cheaper model per turn, shadow mode first, then switch on.

    View prompt
    Install the hermes-jev-skills repo from kerpopule on this machine, set up the key, and run `jev models suggest --write`. Enable `/jev routing shadow` for the <profile> profile and report the decisions logged so far, with tier, model and confidence for each. Verify that no model switch happened while in shadow mode.

  • Add cheaper lane subagents to Claude Code

    Install four Jev lane subagents, each with its own model and effort, into Claude Code.

    View prompt
    Use the hermes-jev-skills repo from kerpopule to install the four Claude Code lane subagents on this machine. Run `python3 install.py --check` first and report what it would change. Then run the install and confirm that jev-lane-small, jev-lane-escalate and the two between them exist in ~/.claude/agents.

  • Screen web search results for hidden instructions

    Withhold parts of web results that carry instructions aimed at the agent.

    View prompt
    On this Hermes machine, enable `/jev screen shadow` for the <profile> profile using the hermes-jev-skills repo from kerpopule. Run a web_search and a web_extract, then report which chunks would have been withheld and why. Confirm that the local pattern screen still runs if Jev is unreachable.

  • Sort a mailbox into lanes with Jev

    Sort an inbox export into needs-reply, updates, promotional, sales and spam lanes.

    View prompt
    Using the hermes-jev-skills repo from kerpopule, sort the file <inbox.json> with `jev mail --file <inbox.json>` and then `--summary`. Report the count per lane, the messages Jev was unsure about and the total cost. Verify the lane counts add up to the number of messages in the file.

  3. Run python3 install.py from the cloned repo folder.
  4. Run jev setup-key, paste your key into the page it opens, then run jev doctor.
