Under the hood
New tengu_prompt_shell_permission telemetry event logs how inline skill shell commands are permission-checked
What
Claude Code now emits a telemetry event called tengu_prompt_shell_permission every time an inline skill shell command runs. It records what permission behavior applied, which permission mode was evaluated, the reason for the decision, and whether the command was ultimately handed to the model.
Why
This gives Anthropic visibility into how permission decisions play out for shell commands embedded in skills, which can help diagnose unexpected approvals or denials.
