Blindness/Deafness

Cut a system's eyes or ears — let it run, but blind to specific inputs or deaf to specific signals.

What This Skill Does

In D&D, Blindness/Deafness selectively removes one sense — the target can still act but loses critical awareness. The real-world version is selective channel muting: blocking a process from seeing certain inputs (input filtering, API response redaction), deafening it to specific signals (suppressing webhooks, ignoring certain event streams), or cutting telemetry so a system operates without awareness of a specific data source. Unlike containment (forcecage) which restricts everything, Blindness/Deafness surgically removes one information channel while leaving the rest intact. In this grimoire, Blindness/Deafness is treated as a literal spell with a shipping-now delivery profile. Canonical reference input: Blindness/Deafness (spell).

When To Use

• A process should keep running, but one input, signal, or telemetry source needs to be removed from its awareness.
• You need to suppress a specific webhook, event stream, API field, or sensor channel without containing the whole system.
• You want to test or control behavior under selective sensory loss rather than full isolation.

Prerequisites

• No extra runtime dependencies beyond Hermes Agent and the normal toolset for this session.
