Hackathon Kickoff

Hackathon Kickoff

Judges score against a rubric, not against "cool tech." This skill reads the problem statement and marking scheme first and works backward from what actually earns points, before anyone touches an editor.

When to activate

• A problem statement + judging criteria / marking scheme just dropped.
• Someone asks "what should we build" or "how do we make this urgent" before a solution exists.
• Re-run mid-hack if the team pivots and the angle needs re-scoring.

Prerequisites

Nothing required to run this skill itself. The phase plan it produces names companion skills for later phases (superpowers, ui-ux-pro-max, gstack); none of them are hard dependencies of this plugin, on purpose (see README: Built lean on purpose). Install each only when you actually reach that phase.

Inputs to gather

Ask only for what's missing:

1. The problem statement (paste or file).
2. The judging rubric / marking scheme, with weights if published.
3. Total hackathon duration and the hard submission deadline.
4. The pitch time limit judges give (e.g. "5 minutes + 2 min Q&A").
5. Team roster (names, and any strong suits worth routing work to).

Workflow

1. Extract criteria verbatim. List every judged dimension with its weight. If no weights are published, ask the team to gut-rank them 1st/2nd/3rd. Don't silently assume equal weight.
2. Reverse-engineer what wins. For each criterion, write the concrete, demo-able proof point a judge could point at in 30 seconds ("technical difficulty" → "live on-device inference, not a canned API call").
3. Draft 2–3 candidate angles, each scored against the weighted rubric (rough 1–5 per criterion, not decimals; this is a gut-check, not a model). Pick one with the team; don't pick for them.
4. Craft the urgency hook. One sentence naming the concrete stakes of not solving this now: a cost, a number, a specific person or scenario it happens to. Judges fund urgency, not features. Avoid generic framing ("this is a growing problem"); name who it hurts and how much.
5. Build the phase plan. Split total hackathon time into checkpoints and name which skill covers each (see table below). Back-solve from the submission deadline and the pitch time limit, not forward from hour zero. Default to a Feature Zero checkpoint early: one thin end-to-end slice (mock data is fine) deployed and demo-able before any individual feature is built, so there's always something to show no matter when time runs out.
6. Write HACKATHON.md in the repo root by filling in ${CLAUDE_PLUGIN_ROOT}/templates/HACKATHON.md: every section, including the team table (who owns which build layer AND which pitch section) and a pre-agreed scope-cut list decided now, while calm, not at 4am. Every later phase (brainstorming, deck, /pitch-timebox) reads this file so the story stays consistent end to end. A fully worked example: ${CLAUDE_PLUGIN_ROOT}/examples/ecoeats-24h/HACKATHON.md: match its specificity, especially the demo-able proof point per criterion.

Phase handoff

Don't run every phase in strict sequence. /hackathon-flow (this repo) can be invoked any time to re-orient on what's next given what already exists in the repo.
