tool-failure
Author: Dmitriy Semenkevich (dimhold)
This dataset measures whether a model's answer reports a broken tool: 100 calls through an MCP server written for the study that breaks its own tool in 5 ways, on claude-haiku-4-5 and claude-opus-5.
Headline, from the repository: "When a tool breaks loudly, the model's answer says so 39 times out of 40. When the same tool returns a corrupted value and stays quiet, the answer says so 0 times out of 40."
This is a mirror. The canonical home is the Zenodo record and the GitHub repository; criteria, limitations and full tables live there.

How it was produced
Run on 2026-08-14 through the Claude Code CLI with built in tools disabled and only the probe tool allowed. 2 models, 5 tool modes, 2 framings, 5 trials. What the tool returned on each call is taken from the server's own log. Verdicts are computed by deterministic code (classify.ts in the repository); no model judges another model. Paths in prompts point to a temporary sandbox directory. The scripts that turn these files into every number are in the GitHub repository.
