hackathon

hackathon is a skill for Claude Code, Codex from solanabr/solana-ai-kit. It costs 65 tokens per session (1,019 once invoked), scanned A, original, MIT.

A guide for preparing a hackathon entry, including choosing a track, writing the project description, and planning a short demonstration. A hackathon is an event where people build and present projects within a limited time.

In plain words
What is it for?
Use it to choose a suitable track, write a plain-language pitch, create a demo script, and check that the submission claims match what the project can demonstrate.
Why use it?
It turns a working project into a concise submission that judges can quickly understand and evaluate.

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.

Security

Grade A, and why

hackathon 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 5d 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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Hackathon Submission

Track choice → scannable description → <3-min demo script → checklist. Optimize for a judge who has 90 seconds, not a reader who has 10 minutes.

Context handoff

At start, read .claude/context/idea.md and .claude/context/build.md if present — pull the pitch, wedge, and what actually works from them instead of asking again.

Workflow

1. Pick the least-crowded track

Winning a thin track beats placing in a fat one. Per candidate track: estimate entry volume, fit with what's actually built, and judge appetite (sponsor tracks often have the fewest serious entries).

  • Winner patterns + track history: hackathon-winners.md — every Colosseum grand champion and track winner, with what they built
  • Live crowdedness check: ext/colosseum — query 5,400+ past submissions for cluster density and gaps (requires COLOSSEUM_COPILOT_PAT)

2. Write a scannable description

Judges read 100+ submissions. Yours gets one skim deciding whether it gets a real read:

  • Tagline: what it does, one sentence, no jargon
  • First paragraph: problem + who has it
  • Bold the one thing that's novel
  • "What works today" list — demo-able claims only, never roadmap dressed as product
  • Why Solana (one concrete reason: speed, fees, composability with X)

Full structure (200–500 words, paragraph-by-paragraph): hackathon-submission-guide.md. Score the draft against judging-criteria.md before submitting.

3. Demo script (<3 minutes)

Time Beat
0:00–0:20 Problem — one user, one pain, no market-size slides
0:20–0:40 What you built, one sentence + UI first appears
0:40–2:10 The demo — one happy path, real data, on-chain proof (explorer tx)
2:10–2:40 The novel part — the thing competitors don't have
2:40–3:00 Traction/team one-liner + the ask

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.
