The Pieces

Every piece has a purpose.

Like a grandmaster's arsenal, each feature plays a critical role in keeping your code in check.

The Queen

AI Change Summaries

The most powerful piece on the board. Scans every direction of your commit and delivers a clear, human-readable breakdown of what changed and why.

The Rook

Change Impact Analysis

Straight-line vision across your entire codebase. Maps exactly which areas are affected - auth, middleware, database, components - no blind spots.

The Bishop

Flow Comparison

Cuts across the board diagonally, seeing what others miss. Visualizes before-and-after behavior side-by-side, no guesswork needed.

The Knight

Smart File Tracking

Moves in ways nobody expects. Jumps between files, additions, and deletions with an intuitive overview that makes complex changes obvious.

The Pawn

Bug Detection

Small but relentless. Advances through your code line by line, spotting issues before they promote into production nightmares.

The King

Standards Compliance

The piece you build your entire strategy around. Enforces team standards and best practices so your codebase stays consistent and defended.

"In chess, the threat is stronger than the execution."
Aron Nimzowitsch

checkmate.sh catches threats before they execute in production.

"Every pawn is a potential queen."
James Mason

Every small bug is a potential outage. We catch the pawns early.

"The pin is mightier than the sword."
Fred Reinfeld

Pinning down issues in code review beats fixing them in prod.

The Game

Watch the board.

Every commit is a move. checkmate.sh plays the counter-move, catching threats before they reach your king.
