Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00026 | $0.01190 |
| Opus 5 | $0.00013 | $0.00595 |
| Sonnet 5 | $0.00005 | $0.00238 |
| Haiku 4.5 | $0.00003 | $0.00119 |
Grade A, and why
beware-of-hallucinated-quotes 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Beware of Hallucinated Quotes & Citations (AI Skill)
Overview
One of the most insidious failure modes of Large Language Models is the generation of plausible but completely fabricated quotations. Models will effortlessly attribute memorable, eloquent aphorisms to historical figures (Albert Einstein, Winston Churchill, Mark Twain, Steve Jobs) or invent non-existent book titles, chapters, and academic paper DOIs.
This skill details the Attribution & Quotation Grounding Protocol: rules and prompts to force verbatim fidelity and prevent embarrassing attribution errors.
Why AI Fakes Quotations
┌─────────────────────────────────────────────────────────────┐
│ The Quote Hallucination Trap │
│ │
│ User: "Give me an inspiring quote by Abraham Lincoln │
│ about digital technology and adaptability." │
│ │
│ AI Semantic Synthesis: │
│ "The dogmas of the quiet past are inadequate to the stormy │
│ present... we must think anew and act anew." │
│ ↳ Model stitches Lincoln's 1862 message to Congress with │
│ synthetic words about 'modern tools' to fit the prompt. │
│ ↳ Result: Confidently fabricated historical quote. │
└─────────────────────────────────────────────────────────────┘
The Attribution Grounding Protocol
Before including an AI-generated quotation in a speech, presentation, manuscript, or legal filing, apply these 3 rules:
- The Exact-Quote Search: Copy the exact quoted sentence in quotation marks (
"...") and search Google Books or Google Scholar. If zero exact matches exist, it is a synthetic fabrication. - Demand Chapter & Primary Source: Require the AI to name the exact book title, publication year, chapter, or primary speech context.
- Paraphrase If Unverified: If you cannot verify the exact primary text, rephrase as a conceptual principle rather than a direct quote.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

beware-of-hallucinated-quotes is a skill published in the GitHub repository alivirgo/Major-AI-Skills (1 stars, last pushed today), licensed MIT. It adds 26 tokens to every session and 1,190 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
