netintel_gas_price

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

With no annotations, the description carries the full burden, and it does add real behavioral context: keyless (no credentials needed), single-call multi-chain coverage, and 'live' freshness. It also previews the return shape (gas price plus EIP-1559 base/priority fee in gwei) before being truncated. It stops short of disclosing rate limits, caching, or failure modes per chain, so it is useful but incomplete.

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

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

The text is dense and front-loads the resource and chain list before the value proposition, which is well ordered and waste-free. However it ends mid-sentence with a trailing ellipsis, indicating the definition is truncated rather than deliberately concise. Compact but structurally unfinished.

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

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

With no output schema and no annotations, the description must explain both behavior and returns; it partially does, naming per-chain fields and units (gwei). What is missing is how the 'chains' argument is supplied and whether the default is all chains. For a single-param read tool this is workable, but not fully self-contained.

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

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

The schema has one parameter, 'chains', with 0% description coverage, so the description must compensate. It lists supported chains, which implies valid values, but never states the parameter's format (comma-separated list vs. repeated arg), whether it is optional, or what happens if omitted. The ellipsis truncates before any such detail.

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

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

The description names a specific resource (live gas prices), enumerates the exact chains covered (Base, Ethereum, Arbitrum, Optimism, Polygon), and states the delivered value (USD cost estimates for transfer, ERC-20 send, and swap). No sibling tool covers gas pricing, so there is nothing to confuse it with. An agent knows immediately what this tool produces.

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

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

Usage is implied rather than stated: 'keyless, one call, all chains' signals it is a batched, no-auth lookup worth preferring over per-chain calls. However, the description never says when to reach for this versus related tools like netintel_crypto_price or netintel_market_snapshot, nor any prerequisite or exclusion. Adequate but leaves routing to inference.

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