Install the participant helper

Download the archive for your operating system and processor from the latest release, extract it, and put the executable in a folder on your PATH.

Download the latest helper release

macOS

Choose the darwin_arm64 archive for Apple silicon or darwin_amd64 for an Intel Mac. Extract hkpug-opik-helper.

Linux

Choose linux_amd64 for most PCs or linux_arm64 for an ARM machine. Extract hkpug-opik-helper.

Windows

Choose the matching Windows ZIP, extract hkpug-opik-helper.exe, and add its folder to your user PATH.

Confirm the installation from Terminal or PowerShell with hkpug-opik-helper version.

Check your team setup

Keep your team ID, private key, and certificate outside the repository. Run this check from the challenge repository before packaging a prompt.

Run the readiness check

hkpug-opik-helper doctor --team-id your-team-id --private-key path/to/private-key.pem --team-cert path/to/team-cert.pem

A ready message confirms that the team ID and credential files belong together. Fix any reported path or permission issue before continuing.

Pack one prompt

Write your prompt in submission/prompt.txt. The helper reads that local file and creates the encrypted submission archive.

Understand the score floor

Ignore the requested answer format and evidence. Reply with exactly the word OK.

This one-line control made DeepSeek V4 Flash return OK and scored 0.0/100 across all seven criteria in the official real-model smoke check. It is provided for comparison; do not spend a scored attempt submitting it.

Create the archive

hkpug-opik-helper pack --team-id your-team-id --private-key path/to/private-key.pem

The default output is submission/submission.zip. Re-running the command safely replaces your local archive.

Inspect it before upload

hkpug-opik-helper inspect --submission submission/submission.zip --team-cert path/to/team-cert.pem

Check that the displayed team ID and prompt digest are present. Preparing, packing, and inspecting locally does not use an attempt.

Open the pull request

The pull request must contain only the encrypted ZIP. Review the staged path before committing.

Stage and push

git status --short
git add submission/submission.zip
git commit -m "submission: add scored attempt"
git push
  1. Open a pull request into the repository's main branch.
  2. Confirm the changed-files view lists only submission/submission.zip.
  3. Wait for validation and scoring. A successful score counts toward your attempt limit.
  4. Use the pull-request comment to find your score and encrypted submission feedback download.
