jcourse_get_hot_courses

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

Annotations already declare readOnly/idempotent/non-destructive, so the safety burden is low. The description earns credit for a real semantic caveat beyond structured data: the hot score reflects community activity, not course rating — this prevents the agent from misreporting the ranking as quality.

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 short clauses, front-loaded with the scope and followed immediately by the disambiguation caveat. Nothing is padded, though the second clause could be framed as actionable guidance rather than a bare statement of fact.

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?

Output schema exists, so return values need no explanation, and annotations cover the safety profile. Still missing: any mention of limit behavior (default 10, max 50) and how results are ordered/paginated, which matters for a ranked-list tool.

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 coverage is 0%, so the description must carry parameter meaning. It covers the period dimension ('本周或本月' maps to the week/month enum) but says nothing about limit, its default, or its 50 cap; the limit parameter stays undocumented in both places.

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 (读取) and resource (热门课程) plus the time scope (本周或本月), which is more than the bare name gives. It is distinguishable from search_courses and list_enrolled_courses, though it never names those siblings 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?

The week/month framing implies a discovery/browsing use case, but there is no explicit when-to-use or when-not-to-use guidance relative to jcourse_search_courses or jcourse_list_enrolled_courses. The agent must infer the selection rule from the name alone.

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