litmus
OrenSegal ★ 0
litmus performs mutation testing on LLM and agent evaluation suites by intentionally breaking the skill under test (deleting instructions, inverting rules, swapping tool names, truncating prompts) and running your evals against each mutation to measure how many breaks your evaluators catch. It runs on top of Claude Code's plugin eval runner and includes offline checks for graders that cannot fail and for cases that pass without the plugin.
