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

With no annotations, the description carries the full disclosure burden; it does add real value by naming the returned artifacts (citation counts, reconstructed abstracts, authors, Open-Access PDF links) and the upstream sources. However it says nothing about latency (the word 'Deep' implies cost without elaborating), rate limits, or whether coverage is deduplicated across the two sources.

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 tight sentences, front-loaded with the purpose and followed immediately by sources and return contents. No filler beyond the mildly redundant 'Deep scientific & academic' pairing.

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 search tool with no output schema, the description usefully enumerates what comes back (citation counts, abstracts, authors, OA PDF links) and where results come from, so the missing output schema is largely compensated. It stops short of stating result ordering or relevance ranking, which an agent might reasonably want.

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%, so both parameters are already fully documented with an example query and a 1-15 default-5 limit. The description adds no syntax, filtering, or range guidance beyond what the schema provides, so the baseline 3 applies.

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 operation (queries OpenAlex and arXiv for peer-reviewed papers and preprints) and names the exact data sources, which no sibling tool covers. The verb+resource+provenance combination lets an agent place it immediately against the other intel/search siblings.

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 framing 'Deep scientific & academic research tool' implies the domain of use but gives no explicit when-to-use condition, no exclusions, and no pointer to alternatives such as domain_intel or web_extract for non-academic queries. Usage must be inferred from the domain label alone.

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