scopus_serial_title_by_issn

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

With no annotations, the description carries the full burden of behavioral disclosure, but it only mentions the default view and a subscription-tier validation. It does not describe whether the operation is read-only, what happens for invalid or unknown ISSNs, how pagination or limits behave, or what the response structure looks like.

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 two sentences that are front-loaded with the tool's core purpose and then a short operational note. It is efficient and avoids filler, though the subscription-tier parenthetical is slightly niche.

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 tool with no output schema, no annotations, and 0% schema description coverage, the description is too thin. It does not cover the view parameter's options, ISSN formatting requirements, error behavior, or expected return shape beyond a high-level field list, leaving agents to guess at important call details.

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%, so the description must compensate, but it only implicitly defines 'issn' as a lookup value and mentions the 'view' default without explaining allowed values or behavior. The listed metadata fields describe output, not parameter meaning, and the view parameter's semantics are left underspecified.

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 a specific verb ('Get') and resource ('journal/serial metadata') with a clear lookup key ('by ISSN'), and lists the fields returned (title, publisher, Open Access status, coverage years, subject areas, homepage). This distinguishes it from the sibling scopus_serial_title_search_by_criteria, which searches by criteria rather than a specific ISSN.

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 use this tool versus alternatives like scopus_serial_title_search_by_criteria. The note about the default view working with a basic subscription tier is a minor operational hint, but it does not explain when to choose this tool over others or mention conditions like 'use when ISSN is known'.

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