Security audit

crypto-gas-fee-optimizer

Security checks across malware telemetry and agentic risk

Overview

This skill is a read-only gas-fee checker that contacts disclosed public price and blockchain RPC services and does not handle wallets, keys, or transactions.

Install this only if you are comfortable with the script making live requests to publicnode.com and CoinGecko when you run it. It does not need wallet secrets and should not be given private keys, seed phrases, or transaction-signing authority.

Finding
The skill declares only `allowed-tools: Bash` but its documented behavior requires outbound network access to public RPC endpoints and CoinGecko. This permission/capability mismatch is a real security issue because it can cause reviewers and enforcement systems to underestimate what the skill does, reducing transparency and potentially allowing unintended data egress or unreviewed remote interactions.
