Scored across 4 tools
Tools are mostly distinct: get_gas_demo and get_cheapest_chain are free but with different outputs (full table vs recommendation), while get_gas_basic and get_gas_premium are paid with increasing chain coverage. However, get_cheapest_chain's recommendation overlaps with get_gas_basic's recommendation, potentially causing minor confusion.
All tools follow a consistent 'get_gas_<descriptor>' pattern (demo, cheapest_chain, basic, premium), making it predictable for an agent to understand the hierarchy and purpose.
With 4 tools, the set is well-scoped for a gas optimizer: free demo, free recommendation, and two paid tiers (basic 4-chain, premium 9-chain). No unnecessary tools and enough to cover core needs.
The tool surface covers the essential domain of multi-chain gas price retrieval: free access, cheapest chain recommendation, and paid detailed comparisons. There are no obvious gaps like missing chain-specific queries or historical data, which are likely out of scope.
