unpaywall_export_ris

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

No annotations are provided, so the description must carry the full burden. It discloses that it exports the most recent results and produces a .ris file, but it does not state behavior when no previous results exist, file naming conventions, or error handling. This is adequate but not comprehensive.

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?

Two concise sentences with no wasted words. The first sentence states the core function, and the second gives a concrete usage instruction. Perfectly front-loaded and efficient.

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?

The tool has no parameters but has an output schema (not shown). The description explains the output file format and a use case, but it does not cover edge cases (e.g., no prior results, multiple results). Given the tool's simplicity, the description is mostly sufficient but misses some context.

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 input schema has zero parameters, and schema coverage is 100%. With no parameters to describe, the description adds no parameter information beyond the schema, but baseline for 0 params is 4. The description naturally cannot add value here.

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 the tool exports the most recent unpaywall lookup or search results to RIS format, which is a specific verb and resource. It distinguishes from sibling tools (unpaywall_export_bibtex exports to BibTeX, unpaywall_lookup and unpaywall_search have different functions).

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 provides explicit context: it exports the most recent results and gives instructions to import into Zotero via File -> Import. It implies a prerequisite (prior lookup/search) but does not explicitly state when not to use it or alternatives (e.g., use unpaywall_export_bibtex for BibTeX format).

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