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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds a genuinely useful behavioral detail — the result is presented as the person sees it, implying permission-scoped visibility. It says nothing about pagination, truncation, or completeness of the Files/Tasks listing, which is the remaining gap.

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?

One front-loaded sentence with the resource and returned contents stated first and the scope qualifier last. Nothing is wasted, though a brief clause on alternatives would have earned the fifth point.

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?

This is a simple single-parameter read tool with rich annotations and no output schema, and the description does enumerate the kind of content returned (texts, links, Files, Tasks). It is nearly complete for its complexity; only the perspective/pagination details of the payload are left implicit.

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% and the single courseId parameter is fully documented, including its source ('from list_courses'). The description adds no additional meaning about the parameter, so 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 verb ('Reads') and resource ('a Course's page') and enumerates the returned content types (texts, links, Files, Tasks). This distinguishes it reasonably from siblings like course_files or list_tasks, though it does not explicitly name an alternative.

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?

There is no explicit when-to-use or when-not-to-use guidance and no named alternative. The phrase 'as the person sees it' hints at a user-scoped view but leaves the agent to infer when to pick this over course_files or list_tasks.

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