Cancel a specific job.
AI agents call cancel_job_tool to permanently remove resources in Qiskit Gym MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Cancelling a job is an irreversible action — once a running job is cancelled, its progress and intermediate results are lost and the operation cannot be undone. This maps to the Destructive category. The blast radius is high because cancelling a quantum circuit synthesis or training job could destroy significant compute work and results.
