有人做了个 Claude Code mod：把失败的测试变成怪物对战

My test suite has a Bugdex now. 🐛

Bugdex is a mod for Claude Code that turns a normal coding session into a monster-battle game. Nothing about the work changes: same files, same tests, same fixes. Bugdex just watches and draws it as a fight.

How a fight goes

• A test, lint, build or merge fails → a wild bug appears. The species comes from the actual error: a TypeError summons a Typhox, Cannot read properties of undefined is a Nullbat, a psycopg2 error is a Querydile, and JavaScript heap out of memory is, naturally, a Heaphant.
• The number of failures is the bug's HP. Every run with fewer failures is a hit.
• Your creature's HP is your free context window.
• The suite goes green → the bug faints and you earn XP.
• To catch it, a test has to be written or fixed during the fight. No regression test, no Bugdex entry.
• Green again with nothing changed? It was a Flakeling all along: a flaky test. 10 XP, as a treat.
• The same file edited 3+ times with no progress → your creature gets Confused. The game's polite way of saying "maybe step in".

You can't farm it: XP only comes from red → green, and losing costs nothing.

There are 20 species so far, all original pixel art (half blocks in the terminal, SVG in the desktop app), and your own creature evolves from Patchling to Patchwarden at Lv16 and Patchtitan at Lv36.

It makes no network requests and no model calls, so it costs zero tokens. It only reads tool output to spot test runs and edits.

Install (needs Claude Code 2.1.286+ with mods):

/plugin marketplace add ahmtsahin/bugdex /plugin install bugdex@bugdex 

Repo: https://github.com/ahmtsahin/bugdex

There's a tiny demo project with a planted bug, so you can meet your first Syntaxon in about a minute.

Which error deserves its own species next? I'm leaning towards a CORS ghost that only haunts browsers. 👻
