The real-world version is deliberate capability reduction: putting a system into safe mode, stripping an overpowered tool down to basic functions, reducing attack surface by removing features. Feeblemind is not punishment — it is the recognition that sometimes a system at full capability is more dangerous than a system at reduced capability. Restricted shells, read-only modes, feature-stripped emergency interfaces. In this grimoire, Feeblemind is treated as a metaphorical spell with a prototype delivery profile. Canonical reference input: Feeblemind (spell). ## When To Use - A system at full capability poses a risk that outweighs the cost of reduced functionality. - You need to reduce attack surface by stripping non-essential features. - A tool or service should be put into safe mode or restricted operation during an incident or investigation. ## 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 which capabilities must be preserved (minimal viable function) and which can be safely stripped. 3. Implement the capability reduction: safe mode, restricted shell, feature stripping, read-only lock. 4. Verify the reduced system still performs its essential function. 5. Document what was removed and the conditions under which full capability should be restored. 6. Set a review point — feeblemind should be temporary unless the full-capability version is permanently retired. 7. Package the result as the deliverables below, with confidence, assumptions, and unresolved risk called out explicitly. ## Deliverables - A capability reduction plan: what stays, what goes, and why. - Confirmation that minimal viable function is preserved. - Restoration criteria: what conditions must be met to return to full capability. ## Pitfalls / Guardrails - Call out the glue, permissions, or missing infrastructure before you imply this is fully operational. - Feeblemind must preserve minimal viable function. Reducing a system to zero capability is Power Word Kill, not Feeblemind. - Capability reduction of user-facing systems requires clear communication about what changed and when it will be restored. - Do not use Feeblemind to permanently hobble systems that should instead be redesigned or decommissioned. ## Verification - Check that the result includes every deliverable promised above. - Check that confirmed facts, assumptions, and inferences are visibly separated. - Check that the metaphor still maps cleanly to a real operational mechanism. - Check that any missing glue code, permissions, or future work is labeled before the skill is treated as ready. ## Example Invocation ```text /feeblemind reduce a system to minimal capability — stripping non-essential features to limit risk while preserving core function ``` ## 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-feeblemind - 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.
