# Antasphere Hackathon

> Antasphere Hackathon is the platform a hackathon runs on: one event with a shared clock, one repository per team, the coaches a message away, the two decks each team presents, and the community vote. Participants use it through the dashboard and the hackathon command line; coaches and the jury through the dashboard.

## Who is who

* **Participants** build. A team is a group of participants with one repository; a solo entrant is a team
  of one and gets the same repository, the same two decks and the same place in the vote.
* **Coaches** (the platform calls them advisors) help every team. They read every team's chat, take the
  help requests and answer in their threads. They have no team, no submission and no ballot.
* **The jury** watches the pitches and scores on paper. On the platform the jury reads the Teams page, with
  each team's demo deck and presentation, and the vote's result once it is released.
* **The organizers** run the event: the schedule, the roster, the team repositories, the vote. Nothing an
  organizer does is on these pages.

Everyone signs in with their Antasphere account. The organizers put your email on the event's roster, and
the platform matches you on it: an account the roster does not name is refused.

## How an event unfolds

1. **Before the day.** The organizers set the schedule and create each team's repository from the event's
   starter, inviting each member's GitHub account. You install the hackathon plugin in Claude Code
   (`/plugin marketplace add antasphere-hackathon/plugin`) and say `/plugin:join`: it installs the CLI,
   connects you and sets up your team's app on your machine
   ([Your hackathon, step by step](/hackathon/getting-started/participants)).
2. **The build.** The clock runs on the server. You push to your team's repository, early and often, and
   check on the Home page that the platform received your last revision. Your team's chat and the help
   requests are on the Chats page, the whole event's feed beside them.
3. **The end of the build.** The build ends at the time the schedule says. Fifteen minutes of grace follow,
   for your final push. Then the freeze: the platform keeps a copy of the last revision it received, and
   nothing pushed after that counts. [The clock, the grace and the freeze](/hackathon/concepts/the-clock)
4. **The pitches.** Each team hands in two Slideless links, a demo deck the jury can play alone and the
   presentation given on stage, and presents live. When the organizers turn the vote on, participants rank
   the other teams. [Decks and the community vote](/hackathon/concepts/decks-and-voting)

## The pages

* **Home**: your place (your role, your team), the clock with its countdown, the notices, and your team's
  submission card with the last received revision.
* **Teams**: every team, its repository and its two decks.
* **Chats**: the general channel, your team's chat and the threads of your help requests, live.
* **Vote**: rank the other teams, and read the leaderboard once it is released. The page appears when the
  organizers turn the vote on.

## The command line and agents

The `hackathon` command line signs in with your Antasphere account, sets up your team's app, checks your
machine, and does from the terminal what the pages do. [The commands](/hackathon/getting-started/commands) is the
page a participant reads; [the CLI reference](/hackathon/agents/cli) names every command for an agent. Every
instance also serves an MCP endpoint for agents, with 71 `hackathon_` tools:
[connect an agent](/hackathon/getting-started/connect-an-agent).

## The Malt × Antasphere Hackathon

The first event on the platform is the [Malt × Antasphere AI Hackathon](/hackathon/events/malt-antasphere-2026)
of 2 October 2026 at WAT, Brussels, and its starter: a tool with hands, ears and a voice.
