LLMSnare

A benchmark for how agents behave

It checks whether a model reads before it writes, and tracks the habits that make an agent reliable.

BENCHMARK

What it measures, what it does not

ONGOING

Tracks regressions over time, not one-off rankings

SCOPE

Not a direct test of capability level

TOOLS

Biased toward tool-calling behavior

LAZY

Checks for lazy early writes

CASE

Case-driven and customizable

LIMITS

These dimensions are not scored directly

EXPLAIN

Every bonus and deduction is explainable

CASES

The mistakes it catches

P-01

Acts before it understands the situation

P-02

Knows it is on the wrong path, but keeps going

P-03

Gets stuck in ambiguity
