Mempool Intrusion Detection System

Mempool Intrusion Detection System is a skill for Claude Code, Codex from XSpoonAi/spoon-awesome-skill. It costs 35 tokens per session (2,897 once invoked), scanned A, original, no licence file.

A real-time system for monitoring the blockchain mempool for possible exploit attempts. It uses machine-learning classification and can carry out defensive responses with attention to transaction fees.

In plain words
What is it for?
Use it to monitor pending blockchain transactions, classify possible exploits, and trigger defensive responses.
Why use it?
It helps detect suspicious activity while transactions are still pending, when there may be time to respond.

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

Mempool Intrusion Detection System 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 9d ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/defense_executor.py, scripts/exploit_classifier.py, scripts/ids_engine.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Changes

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.
