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

With no annotations, the description carries the burden. It discloses email privacy (sent to Crossref, etc.) and confidential_mode behavior, but omits side effects of other parameters like s2_api_key, core_api_key, and show, nor does it mention reversibility or immediate effects.

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 and front-loads the primary purpose. The narrative style is efficient, though the formatting could be more structured for quick scanning. No wasted words, but some information is buried in paragraphs.

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 6 parameters and no annotations, the description is incomplete. It fails to mention show, s2_api_key, and core_api_key, and provides only shallow detail on library. An agent cannot correctly set all options without additional knowledge, and the output schema is not explained.

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 explain all parameters. It covers email, library, and confidential_mode with some detail, but completely omits show, s2_api_key, and core_api_key, leaving those undocumented. The explanation for email and confidential_mode is helpful but incomplete for the full parameter set.

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's purpose: setting contact address, library location, or confidential mode. It distinguishes itself from sibling research tools by being a configuration tool, so an agent can immediately identify its role.

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 implies when to use it (for configuration) but provides no explicit when-to-use vs alternatives or exclusions. Since it's a unique config tool, the context is clear but not formally stated.

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