Generate Secure Share Link

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

The description discloses that the tool returns a secure URL that opens in the Materio viewer, and that it accepts alternative parameter sets. However, with no annotations, it fails to disclose whether the tool has side effects, requires authentication, or has rate limits. The behavioral details are present 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?

The description is concise and well-structured: first sentence states the core purpose, second provides use-case context, and third explains input options. Every sentence adds value without redundancy.

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 the absence of an output schema, the description provides a clear return type ('secure URL') with an example format. It covers the main inputs and usage scenario. However, it lacks details on link expiration, response structure, or error handling, though these are not critical for basic 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?

The input schema already provides 100% coverage with descriptions for each parameter. The description adds value by clarifying the mutual exclusivity of the 'url' parameter versus the 'semester, subject, topic' group, which is not evident from the schema alone.

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: generating a professional masked share link for a Materio PDF. It specifies the output is a secure URL and gives an example. This distinguishes it from sibling tools like fetch_pdf and get_resource, which serve 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 usage context: 'Use this when finalizing a study session or providing resources to the user.' It also explains the two input modes (url or semester/subject/topic). However, it does not explicitly state when not to use this tool or mention alternatives among siblings.

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