Watch your context rot.

A Claude Code mod. The Claude logo sits above the prompt, top right, and decays as the context window fills. Compact or clear and it heals.

  1. Fresh 0-30% Normal orange.
  2. Zombie 30-65% Green, with blood that grows.
  3. Bone 65-90% Bone spreads from the top-left of the head.
  4. Skeleton 90%+ Full skeleton.

Four stages
of decay.

The logo is the gauge. You can tell how full the window is without reading a number.

  1. Fresh 0-30%

    Plenty of room left. The logo looks like the logo.

  2. Zombie 30-65%

    Past 30% it turns green and starts to bleed. The blood keeps spreading until 65%.

  3. Bone 65-90%

    Bone breaks through at the top-left of the head and works its way across.

  4. Skeleton 90%+

    At 90% it's a skeleton. Time to compact.

Install.

One command inside Claude Code. Answer y to add the marketplace, then pick the user scope.

Claude Code

/plugin install context-zombie --marketplace thepragmaticbear/context-zombie

Try the stages

/zombie off   # reset

No need to burn a context window to see the skeleton. /compact or /clear heals it for real.
