🥊 Claude Combo: a fighting-game combo meter for Claude Code

Claude Combo turns your Claude Code session into an arcade fight. Every clean tool call is a hit, every error breaks the chain, and you climb from D to SSS while a pixel-art counter, a status line and chiptune effects keep score. It's a free, open-source Claude Code mod (a plugin of function hooks): a streak counter, combo tracker and status line in one.

 ▀▄▀ ▀█▀ ▀█▀   ▐ B ▌ BLAZING  ×2  1,240 pts
 ▄▀▄  █  ▄▄█   ████████████░░░░░░░░  5 to A
               ✦ RED→GREEN TATSUMAKI  pnpm test  +250

Why? A long agent session is hours of tool calls. Claude Combo turns "did that run clean?" into a number you can see, so a failing test breaks your streak and a green one feels good.

Install

From the marketplace (recommended):

claude plugin marketplace add sarthak2511/claude-combo
claude plugin install combo-meter@sarthak-mods

From a local clone, for one session:

git clone https://github.com/sarthak2511/claude-combo
claude --plugin-dir ./claude-combo

Then run a few tool calls. The band appears above the prompt after your first hit. Type /combo for the fight card.

How scoring works

Each tool call is a move. Points are multiplied by your combo: ×2 from 10 hits, up to ×5.

| Tool call | Move | Points | |---|---|---| | Read | JAB | 10 | | Grep / Glob | SCOUT | 10 | | Edit | SLASH | 25 | | Write | UPPERCUT | 30 | | Bash | HADOUKEN | 20 | | Bash running tests | RISING TEST | 50 | | git commit | SEAL | 60 | | Agent / subagent | ASSIST | 40 | | MCP tool | SUMMON | 20 |

Special moves

| Special | How to land it | Bonus | |---|---|---| | RED→GREEN TATSUMAKI | Read → Edit → passing test | +150 | | SEEK & STRIKE | Grep → Read → Edit | +80 | | TRIPLE SLASH | Three edits in a row | +100 | | COMEBACK! | Tests pass after they failed | +200 | | FLAWLESS VICTORY | git commit on a 20+ combo | +300 | | PERFECT TURN | 8+ hits in one turn, zero errors | +10 per hit |

Ranks

D DECENT (3) · C CLEAN (6) · B BLAZING (10) · A ATOMIC (16) · S SHIPPING (25) · SS SENIOR STAFF (40) · SSS SMOKIN' SHIP STYLE (60)

What breaks a combo

A tool call that errors: a failing command, a failing test, an edit that didn't apply. A call you deny is a parry. It doesn't count as a hit, but it doesn't break the chain either.

What you see

• Band above the prompt: a pixel-art combo counter drawn with half blocks, a heat meter to the next rank and your last move. It falls back to text on desktop, VS Code and mobile surfaces.
• Status line: ⚡ x23 A · 4,180 pts
• Toasts for rank ups, specials, breaks, new records and perfect turns.
• Chiptune sound effects for the big moments. They play on macOS only, and the .wav files are generated by tools/make-sfx.py.
• /combo shows the session's fight card. /combo reset-best clears your all-time record.

Options

Change them in /config:

| Option | Default | | |---|---|---| | sound | true | Chiptune effects (macOS) | | style | big | big pixel counter, or compact one-line text band |

Footprint

Claude Combo only hooks session.start, turn.start, tool.call, turn.complete, session.end, command.run (/combo) and ui.render (the band). It reads each tool call's name and its file path or command head to name the move. It makes no network requests, never reads file contents, and stores only your best combo and score through $.store. Run claude plugin validate . to see the full list of calls it makes.

FAQ

Does it slow Claude Code down? No. Each hook does a few pure-function updates, and the sound is fire-and-forget.

Does it change what Claude does? No. It observes tool calls and always passes them through unchanged.

Does it work in the desktop app and VS Code? Yes, with a text band instead of the pixel counter.

Can I change the ranks, points or moves? They live in hooks/combo.ts, a pure file with no engine dependencies.

Development

Issues and PRs are welcome. New moves and specials especially.
