03Champion playbook

  1. Name a sharp pain pointKiro's own Grand Prize framing: "the difficulty of vibe coding complex computer vision logic without hallucinations." Not "an AI app" — a specific wedge.
  2. Ship a template with two demo apps insideInteractionKit ships Math-O-Lantern (game) + Holo-Board (video tool). The demo apps double as the demo video script.
  3. Zero setup friction./setup.sh and it runs. Judges test repos; every manual step costs points.
  4. Cover every Kiro feature with a concrete artifact3 hooks that auto-integrate new gestures · steering docs for architecture & testing · spec workflow with a copy-paste example spec in the README · MCP (Context7) wired in .kiro/settings.
  5. The README is the "how Kiro was used" write-upJudged criterion: "how thoroughly and skillfully does the project use Kiro". Time-shares (~40% vibe / 30% spec / 15% hooks / 10% steering / 5% MCP), example prompts, measured outcomes.
  6. Honesty differentiates2026 rival seance-relay-chat logs which spec task actually ran in Kiro (3.8 credits) and which hook didn't fire. Against inflated claims, verified honesty reads as maturity.

04Prize lanes — students stack

Rule: one project wins ONE of (Overall 1st/2nd/3rd) OR ONE category prize — plus any number of bonus prizes. Both of us are students → every student lane is open.

Overall

1st $30,000 · 2nd $20,000 · 3rd $10,000

Categories

Best Resurrection / Frankenstein / Skeleton Crew / Costume Contest — $5,000 each

Student lanes

4 × $1,500 + 1-year Kiro Pro Max — highest-scoring all-student submission per category

Bonus lanes

Blog post ≈100 × $1,000 · Social Blitz ×5 (Pro+) · Best Startup $10k · Best Crew App $1k · Best Ghost of Kiroween Past $2k · Best Demo

Realistic Costume-lane stack: Best Costume $5,000 + Best Student: Costume $1,500 + Pro Max + blog $1,000 + social Pro+ — smaller pool than the overall, and nobody in the visible 2026 field is competing on art strength.

05Idea shortlist

After Dark Forever Resurrection

Screensaver culture revival — a platform where generative artists publish modern flying-toasters-style screensavers (web + desktop).

Local-first CRDT starter Skeleton Crew

One skeleton powering a collaborative whiteboard AND a collaborative spooky playlist — exactly the "2 distinct apps" versatility the category brief demands. (InteractionKit won the whole event with this shape.)

⚠ Crowded graves — avoid

Wayback/link-rot resurrection: 2 rivals already public in 2026 + ~5 similar 2025 entries. GeoCities: won last year (GeoSpirits). IRC: resurrected twice.
