near_explorer_url

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

No annotations exist, so the description carries the full burden, and it says nothing about behavior beyond the one-line purpose. It does not state that this is a pure local string-building operation (no network call, no auth, no rate limits), nor whether the resulting URL is mainnet or testnet.

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?

A single front-loaded sentence with zero filler that names the action, the output artifact, and the three supported inputs.

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?

For a two-parameter, no-output-schema helper this is close to adequate, but a network dimension (mainnet/testnet) is never mentioned and could change the returned URL. With no annotations to fall back on, that omission leaves a real gap.

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?

Schema description coverage is 100% and the type enum is self-explanatory, so the schema already does the work. The description adds only the mapping of the three enum values to the entity kinds, which is a marginal restatement of the schema.

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?

States a specific verb (Generate) and resource (NEAR Explorer URL) with the three supported entity types. It is immediately distinguishable from every sibling, all of which fetch chain data rather than build links.

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?

There is no guidance on when to prefer this over siblings or any indication of prerequisites. The only routing hint is implicit in the enum-to-id correspondence, which an agent must infer from the schema.

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