A numeric severity prompt variant is present, used only when severityByModel lists your model in tengu_auto_mode_config.
What
When a severity config exists for the current model, the auto-mode classifier prompt is rewritten to ask for a numeric score rather than a block decision. Without that config the prompt keeps its existing form.
Details
- the trailing "## Output Format" section is replaced to demand
<severity>N</severity>on a 0 to 100 scale, with 50 as the allow/block boundary, instead of<block>yes/no</block> - gated on
severityByModelintengu_auto_mode_config; models absent from that map take the unchanged path - the permission rules injected into the classifier prompt are wrapped in
<cc_automode_permissions>tags - denials taken because auto-mode is active use a distinct user-facing message naming the mode
Evidence
Permission to use ${e} has been denied because Claude Code is running in don't ask mode.
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
