get_gas_price

Get current gas prices for Ethereum, Arbitrum, Base, Polygon, or Optimism. Returns safe, standard, and fast gas prices in Gwei with USD cost estimate for ERC-20 transfers.

Instructions

Get current gas prices across urgency levels for a given chain. FREE.

Returns safe/standard/fast gas prices in Gwei with USD cost estimate for a standard ERC-20 transfer (21,000 gas).

Use this when: an agent needs current gas cost before executing a transaction. Follow with get_optimal_gas_window to decide whether to wait.

Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. It explains output (safe/standard/fast prices in Gwei with USD estimate) and notes it's free, but does not disclose if it's read-only, rate limits, or potential errors.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three sentences, no wasted words. Front-loaded with purpose, then output details, then usage guidance. Perfectly structured for an agent to quickly grasp.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple tool with one parameter and existing output schema, the description covers essential usage, output, and follow-up. Could mention return structure, but output schema handles that.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so baseline 3. The description adds value by stating the chain parameter and default, but the schema already describes it well with example options.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Get current gas prices across urgency levels for a given chain' with a specific verb and resource, and distinguishes from sibling tool 'get_optimal_gas_window' by noting it as a follow-up.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states 'Use this when: an agent needs current gas cost before executing a transaction' and suggests a subsequent tool, providing clear context and alternatives.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
