get_doi_url

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

No annotations provided. Description discloses basic behavior (getting a URL) but lacks details on error handling, authentication needs, or rate limits. For a simple read tool, minimal disclosure is acceptable but could be improved.

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?

Description is concise with clear sections (Args, Returns, Examples). Every sentence adds value; no waste.

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?

Tool is simple with one parameter and an output schema. Description covers functionality, parameter, return value, and example, making it fully complete for agent use.

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 coverage is 0%, but description adds 'Digital Object Identifier' and provides an example, compensating for schema gaps. Adds meaningful context beyond parameter name.

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 clearly states 'Get the URL for a DOI', specifying the verb 'get' and resource 'URL for a DOI'. It distinguishes from sibling tool 'get_pmc_url' which handles PMC IDs instead.

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?

No explicit guidance on when to use this tool versus alternatives. The context implies it's for DOIs (vs. PMC IDs for get_pmc_url), but no clear when-not or alternative mentions.

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