A tool for creating, managing, previewing, listing, and hosting Kahoot quizzes from JSON files. Kahoot is an online quiz platform used for live, interactive questions.

Use it to log in, create quizzes from JSON definitions, preview or list quizzes, and host them live.

It removes the need to build and run quizzes manually through the Kahoot interface. Previewing before going live helps check a quiz before participants join.

Per session 36 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

Origin original No closer match found in the catalogue.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00036	$0.00921
Opus 5	$0.00018	$0.00461
Sonnet 5	$0.00007	$0.00184
Haiku 4.5	$0.00004	$0.00092

Measured 8d ago against content hash 98513f517db7, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-08, from the pricing page.

Security

Grade A, and why

kahoot scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Kahoot Skill — Quiz Management & Hosting

Create, manage, and host Kahoot quizzes from JSON definitions via the kahoot-creator.js CLI.

When This Skill Activates

Explicit: /kahoot-skill:kahoot, /kahoot-skill:kahoot list

Prerequisites

.env in your project root with KAHOOT_TOKEN
Token: Run login to authenticate via browser (auto-detects login, browser closes automatically). Use login --browser msedge for SSO via Edge.
Quiz JSON: A .json file with quiz definition (see format below)

Workflow

Phase 1: Parse Command

Parse $ARGUMENTS — if arguments provided, proceed to Phase 2.
If empty, present the Command Reference and ask which command to run.

Phase 2: Execute

login: Execute directly — opens browser for authentication.

Read-only (preview, list): Execute directly.

NODE_PATH="${CLAUDE_PLUGIN_DATA}/node_modules" node "${CLAUDE_PLUGIN_ROOT}/scripts/kahoot-creator.js" <command> <args...>

create: Execute WITHOUT --live first (dry-run default). Then ask for confirmation.

NODE_PATH="${CLAUDE_PLUGIN_DATA}/node_modules" node "${CLAUDE_PLUGIN_ROOT}/scripts/kahoot-creator.js" create <quiz.json> --live

host: Execute directly — opens the game lobby in the default browser. Accepts a quiz UUID, Kahoot URL, or a quiz JSON file.

NODE_PATH="${CLAUDE_PLUGIN_DATA}/node_modules" node "${CLAUDE_PLUGIN_ROOT}/scripts/kahoot-creator.js" host <uuid|url|quiz.json>

Command Reference

Command	Arguments	Description
`login`	`[--browser msedge\|chrome]`	Open browser, login, save token to .env (auto-closes)
`preview`	`<quiz.json>`	Validate and show quiz structure (no API call)
`create`	`<quiz.json> [--live]`	Create quiz via Kahoot API
`list`	—	List all own Kahoots
`host`	`<uuid\|url\|quiz.json>`	Open game lobby in default browser

Quiz JSON Format

{
  "title": "My Quiz",
  "description": "Optional description",
  "language": "en",
  "timeLimit": 20,
  "questions": [
    {
      "question": "What is 2 + 2?",
      "choices": [
        { "answer": "4", "correct": true },
        { "answer": "5", "correct": false },
        { "answer": "3", "correct": false }

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
