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

Annotations already declare readOnlyHint and openWorldHint, so the safety profile is covered; the description adds the non-obvious constraint that the server has no launch/track coverage at all. Output schema exists, so return shape needn't be described. It could still mention authorization or behavior on invalid course ids.

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?

Two sentences, no filler, with the capability stated first and the limitation immediately after. Every clause carries information an agent needs.

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?

For a one-parameter read-only list tool with annotations and an output schema, this is close to sufficient. The remaining minor gap is what happens with course ids the user cannot access or that contain no SCORM packages.

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?

Single parameter with 100% schema description coverage, so the schema already does the work; the description's 'one or more courses' reinforces that course_ids is a list rather than a single id. No further format or ordering detail is offered.

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 and resource ('List SCORM packaged-content activities') plus scope ('across one or more courses'). It distinguishes itself implicitly from neighbouring list_* tools (list_h5p_activities, list_lessons) by naming the SCORM content type, though it never names a sibling explicitly.

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?

Explicitly delimits what this tool is not for: launching or tracking a SCORM attempt is unsupported, so an agent won't select it hoping to start or advance an attempt. It stops short of pointing at an alternative for attempt tracking, so it's clear context without full routing.

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