How to inspect the Pokémon harness archive locally with Jev Harness

Run the bundled Pokémon example viewer to review decisions without making any model requests.

Who it is forA developer or researcher who wants to see how an evolved harness changed decisions before building one.

The problemReading harness code alone does not show how it behaved in actual games.

The outcomeA local viewer showing the archived run, the evolution tree, and complete decision records with synchronized Jev answers.

What you need first

  • Claude Code or Codex installed
  • Git, and Node.js for the local archive viewer
  • Access to Jev model calls, since plugin installation does not configure model keys
  • A Python environment if you plan to build and run a harness yourself

Steps

  1. Run git clone https://github.com/TianyuCodings/JevHarness.git.
  2. Run cd JevHarness.
  3. Run node website/build.mjs.
  4. Run node website/preview.mjs --port 8768.
  5. Open http://localhost:8768 in a modern browser.

Prompt for your agent

Clone https://github.com/TianyuCodings/JevHarness, build and preview the website with Node.js on port 8768, then report the number of archived Eval games shown on the page. Expected output: the viewer loads at localhost:8768. Verify that browsing makes no model requests and starts no games.

Caveat. Battle animations download assets from the official Pokémon Showdown renderer, so the viewer needs network access for them.
