classify_learning_portal

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

No annotations are provided, so the description carries the full behavioral burden. It discloses only that the tool avoids fabricating navigation URLs; it does not say whether the operation is read-only, what it returns, what errors may occur, or whether it requires prior page state.

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 a single front-loaded sentence with no wasted words. It is very terse and somewhat fragmentary, but that is a content gap rather than structural verbosity.

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 output schema exists, so return-value details need not be in the description. For a simple one-parameter classifier, the description covers the core purpose and an anti-fabrication constraint, but it leaves usage context and parameter meaning under-specified.

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% for the single page_url parameter. The description mentions portal hosts/paths but does not explain that page_url is the input, what URL format is expected, or how the host/path should be supplied.

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/resource pair: classify exact portal hosts/paths. The anti-fabrication constraint also signals this is a classification tool rather than a navigation tool, which helps distinguish it from sibling tools like goto_course_page. It does not name a sibling alternative, so a 4 rather than 5.

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 phrase 'without fabricating navigation URLs' implies a constraint on how results should be used, but there is no explicit when-to-use, when-not-to-use, or alternative-tool guidance among the many sibling navigation and inspection tools. The agent must infer the usage context.

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