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

Beyond the annotations, it discloses that over-limit or unsupported files are automatically excluded and announced, that LMS login is required via mcp_session_id, and that the tool only prepares queue registration rather than performing the export itself. It does not describe side effects or return shape, but the annotations already provide idempotency/read-only/destructive hints.

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 compact and every sentence earns its place: purpose, usage precondition, parameter sourcing, exclusion behavior, and authentication requirement are all covered. There is no filler or redundant restatement of the tool name.

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 description provides enough to invoke the tool correctly, including what to pass and where the values come from. However, there is no output schema and the description does not explain what the tool returns or how to proceed to the likely next step, confirm_lms_material_export, which leaves the full workflow slightly incomplete.

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 the baseline is 3. The description adds meaningful provenance for content_ids by saying they come directly from get_my_lms_courses and that get_my_lms_materials need not be called again. The statement 'mcp_session_id 필요' is slightly inconsistent with the schema's optional bound-session fallback, but the parameter is otherwise well covered.

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 action (validates and prepares queue registration) for a specific resource (LMS weekly materials of a user-selected course). It also frames itself as the basic flow for a specific-course download, which distinguishes it from export_all_lms_materials and confirm_lms_material_export.

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 gives a clear call sequence: show get_my_lms_courses results to the user, let them choose a course, then pass that response's content_ids. It explicitly tells the agent not to re-call get_my_lms_materials. It does not explicitly name sibling alternatives like export_all_lms_materials or confirm_lms_material_export, so the exclusion guidance is incomplete.

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