get_latest_series

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

The readOnlyHint annotation already indicates this is a safe read operation, so the description gains no credit for that. The description adds no additional behavioral details such as default sorting, paging behavior, or what 'recently' means in terms of time. It is a bare statement that repeats the implication of the annotation.

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 short sentence and is technically concise, but it is so minimal that it omits necessary context. While there is no wasted text, the lack of detail means the sentence does not fully earn its place; it is more under-specified than efficiently concise.

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 seven parameters, an output schema, and a large set of sibling tools, the description is insufficiently complete. It does not explain the tool's relationship to similar series-list tools, parameter behavior, or typical use cases. The one-sentence description is far too thin for the complexity and context involved.

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 input schema has 7 parameters with zero description coverage, and the tool description mentions none of them. Since schema descriptions are absent, the description carries the full burden of explaining parameters like 'deleted', 'oneshot', 'sort', and 'library_id'. The description fails to provide any parameter semantics whatsoever.

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 uses a specific verb 'List' and identifies the resource 'series' with a scope 'recently added or updated.' It clearly states what the tool does, but it does not differentiate from sibling tools like get_new_series and get_updated_series, which appear to cover overlapping subsets of this functionality.

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 on when to use this tool versus alternatives. Given the existence of get_new_series and get_updated_series, an explicit mention of whether this tool combines both, or when to prefer one over the others, is needed. The current description simply states what it does without usage context.

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