feeblemind

feeblemind is a skill for Claude Code, Codex from Hmbown/Wizards-of-the-Ghosts. It costs 108 tokens per session (821 once invoked), scanned A, original, CC0-1.0.

A safe-mode procedure that reduces a system to only its essential capabilities, such as restricted or read-only operation.

In plain words
What is it for?
It helps restrict shells, disable non-essential features, and operate tools or services in a limited emergency mode.
Why use it?
It lowers risk and the system's attack surface when full functionality is unsafe during an incident or investigation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

feeblemind scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Feeblemind

Strip a system down to minimal capability when full power is too dangerous.

What This Skill Does

In D&D, Feeblemind crushes a creature's Intelligence and Charisma to near-zero — leaving them alive but barely functional. 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.
