Fetch multiple Gopher resources

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

Annotations already declare readOnlyHint=true and openWorldHint=true. The description adds the behavioral detail that it uses asyncio.gather() for concurrent fetching, enhancing transparency beyond annotations. No contradiction.

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 description is concise with no filler. It front-loads the main purpose, then provides context and parameter/return details in a structured manner.

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?

Given the tool has an output schema, the description suffices by explaining the return order and length, and specifying a limit of 50 URLs. It covers all needed context for an agent to use the tool correctly.

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 0%, but the description clearly explains the 'urls' parameter as 'List of Gopher URLs to fetch (at most 50 per call)' and describes return order and length, adding significant meaning.

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 states 'Fetch multiple Gopher URLs in parallel' with a specific verb and resource. It distinguishes from sibling 'gopher_fetch' which fetches a single URL, and from 'gemini_batch_fetch' which is for Gemini protocol.

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?

The description says 'Useful for fetching multiple menu items or related resources at once', providing clear context. It implies not for single fetches but does not explicitly state when not to use or name alternatives.

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