VoidSense
VoidSense is a Fabric client-side assistant that watches a player's situation and warns before a fall, a fight or a lava pool turns deadly.
What it does
Warnings appear on screen as colored alerts: yellow for caution, orange for a likely stop, and red when the chance of death is high. The alerts are driven by a Bayesian model that weighs the surroundings, health, armor and nearby mobs, and it learns from the player's own habits over time. Warnings can come earlier near lava or in the dark, where deaths tend to cluster.
Because the model keeps a record of past deaths, it can point out repeated mistakes such as mining for long stretches without rest or walking while looking at a phone. The mod requires Fabric API. It is client-side only, so the server needs nothing and vanilla servers work as they are. Files are published for Fabric only, for 1.21.4 – 1.21.11, with 1.0.0 for 1.21.11 as the latest file, and the code is open source under the MIT License.
Key features
Predictive death warnings
A Bayesian model estimates the probability of death from the current situation and shows colored alerts as the risk rises.
Learned playstyle
The assistant tracks past deaths and habits, so later warnings reflect the patterns of the individual player.
Hazard-specific alerts
Alerts cover mobs close behind, low health, armor that is close to breaking, lava and darkness.
Habit reports
Repeated causes of death, such as long mining sessions or missed meals, are surfaced as specific advice.

Use cases
Long mining sessions
A player who has been underground for hours gets a warning before fatigue leads to a careless fall or a lava mistake.
Cave and lava exploration
Warnings start earlier near lava, which helps players who have lost diamonds to a single misstep.
Who it’s for: Players on Fabric who want extra warnings during survival play, and who are willing to let a client-side model learn from their deaths.
How it compares
Careful Bro is a Fabric client-side mod for 1.21.11, released under CC0 1.0 Universal and open source, so it is a plain alert rather than a learning model. Mining Assistant is a Fabric client-side mod for 1.21.1 under the MIT License, but it is not open source. BackAlert is a Fabric client-side mod covering 1.21.1 – 1.21.11 under the MIT License, and it is not open source either.
