get_next_lecture

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

There are no annotations, so the description carries full responsibility for behavioral disclosure. It only states what the tool returns, but does not explain how 'next upcoming' is determined, what happens when no incomplete lecture exists, or whether it returns null, an error, or an empty result. This is a significant gap for a tool with no annotations.

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 a single, focused sentence with no filler or redundant elaboration. Every word contributes to the meaning, and the core action is front-loaded.

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?

With no output schema, no annotations, and no parameter complexity, the description must compensate by explaining the return behavior and edge cases. It does not. An agent cannot infer what the response looks like, what 'incomplete' means in this domain, or how 'next upcoming' is computed, making the tool definition 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?

The tool has zero parameters, so there are no parameter semantics to document. The description need not add parameter-level information; the schema already reflects an empty object with 100% coverage.

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 a specific verb ('Get'), a specific resource ('lecture'), and precise qualifiers ('next upcoming incomplete'). This distinguishes it from sibling tools like get_lecture (generic lecture retrieval), get_today_schedule/get_upcoming_schedule (schedules, not single lectures), and get_oldest_backlog_lecture (different ordering).

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?

No guidance is provided about when to use this tool versus alternatives. With fifteen sibling tools, many involving lectures and backlog, the description offers no explicit conditions or exclusions that would help an agent choose this over get_oldest_backlog_lecture or get_lecture.

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