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. ## Procedure 1. Restate the target, the success condition, and any no-touch boundaries before taking action. 2. Identify the exact channel to mute and the decisions the system currently makes from it. 3. Verify the channel is not safety-critical or load-bearing for core correctness. 4. Choose the muting mechanism: input filtering, response redaction, event suppression, or telemetry cutoff. 5. Define restoration triggers, operators, and monitoring so everyone knows the system is partially blind or deaf. 6. Return the channel-muting plan with expected behavioral changes and rollback steps. 7. Stop for explicit confirmation before taking a live action that changes access, triggers an alert, or touches a real system boundary. 8. Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly. ## Deliverables - A selective channel-muting plan naming exactly what input, signal, or telemetry was removed. - A dependency note explaining what decisions will proceed without that awareness channel. - Restoration triggers, rollback steps, and operator-facing documentation. ## Pitfalls / Guardrails - Treat the live action surface as real operational work, not decorative lore. - Muting a channel the system needs for safety decisions is dangerous. Verify the blinded input is not load-bearing before cutting it. - Always document what was muted and set a restoration trigger. A system that forgets it is blind will make confident wrong decisions. ## Verification - Check that the result includes every deliverable promised above. - Check that confirmed facts, assumptions, and inferences are visibly separated. - Check that the exact live target, confirmation gate, and rollback or recovery path are explicit. ## Example Invocation ```text /blindness-deafness selectively blind or deafen this system to one input, signal, or telemetry source while keeping the rest of it running safely ``` ## Source & license This open-source skill is cataloged on AgentStack and links to its original source — we do not rehost the code. - **Author:** [Hmbown](https://github.com/Hmbown) - **Source:** [Hmbown/Wizards-of-the-Ghosts](https://github.com/Hmbown/Wizards-of-the-Ghosts) - **License:** CC0-1.0 Install and usage instructions live in the source repository linked above. ## Pricing - **Free** — Free ## Security capabilities Automated source analysis of v0.1.0 — what this tool can access: - **Network access:** no - **Filesystem access:** no - **Shell / process execution:** no - **Environment & secrets:** no - **Dynamic code execution:** no *"Yes" means the capability is present in the source — more access means more to trust, not that it is unsafe.* ## Versions - **0.1.0** — security scan: passed — Imported from the upstream source. ## Links - Listing page: https://agentstack.voostack.com/l/skill-hmbown-wizards-of-the-ghosts-blindness-deafness - Seller: https://agentstack.voostack.com/s/hmbown - Browse the marketplace: https://agentstack.voostack.com/browse --- Listed on AgentStack — the marketplace for AI agent skills and MCP servers.
