Head-to-tail sets

Dressed for the job.

Dev desk, tide pool, on call, now playing: sets that go from hat to claw to shell.

Five Shellbys dressed head to tail: a dev desk set, a tide pool set, an on-call set, headphones and a boombox, and the Golden Conch shell
Character sheet

Your work, as stats.

Shipping

Pushes, deploys, and issues taken all the way to a pull request.

Rigour

Passing test runs, failing tests turned green, flaky tests fixed, clean dependency audits.

Craft

Skills, agents and mods he writes for himself.

Tidiness

Idle plugins and MCP servers turned off, crowded conversations started fresh.

A class

Shipper, Tester, Toolsmith, Curator, or a dual class, from the highest stat. Each tops out at 99.

Your week

A weekly crab card every Friday: what you shipped, your streak and new trophies.

Shell stickers

A sticker for every project you ship.

Drawn from the repo itself, going paper, vinyl, holo and foil as you keep shipping. Every shell keeps its own, and friends can see them too.

  • The Sticker Book

    His shell up close, and every sticker you've earned.

  • The crab card

    A card of him as he's dressed, to share.

  • Earned, not bought

    A clean dependency audit earns a project's sticker a fresh shine.

The Sticker Book: stickers in foil, holo, vinyl and paper
The Bugdex

Every bug Claude fixes is a creature in a jar.

A TypeError is a Shapeshifter Shrimp, ENOENT a hermit crab that lost its shell, a merge conflict a crab with two heads, a flaky test a ghost. 66 to catch in twelve habitats.

Only a real fix catches one

Seeing one isn't enough. A skipped test or an @ts-ignore doesn't fool him.

Bug battles

While one is loose, its HP drops as failing tests clear, helpers join in, and the fix knocks it into the jar.

They evolve

Catch one often enough and it evolves.

Badges and the league

Beat each habitat's boss for its badge, then the Deep Four and the champion for the Hall of Fame.

Your crew pitches in

Helper crabs fight alongside him.

For everyone

Sound, motion and screen readers are all looked after.

More hats, effects, colours and voices from other people, installed in one click, checked before anything lands. Packs are pixel art and settings only: they can't run code.
