get_updated_series

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

The description adds the behavioral scope of excluding newly added series, but it does not disclose how 'updated' is determined or any additional behavior. The readOnlyHint annotation is present, and the description is consistent with it, though it does not add significant behavioral context beyond 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 concise sentence that directly conveys the tool's purpose without wasted words. It is front-loaded and appropriately sized.

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?

Despite having an output schema and readOnly annotation, the description is too brief to be complete for a tool with 7 parameters and no schema descriptions. It fails to define what 'updated' means, what filtering options are available, or how the pagination/sorting parameters behave, making it inadequate for effective invocation.

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 description provides no information about any of the 7 parameters in the schema. Since the schema has zero coverage, the description must compensate, but it does not mention page, size, sort, deleted, oneshot, unpaged, or library_id at all, leaving the agent without guidance on how to use them meaningfully.

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 the tool lists series that were updated but not newly added, using a specific verb and resource. This distinguishes it from sibling tools like get_new_series, which lists new series.

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 implicitly contrasts updated series with newly added ones, giving a clear context for when to use this tool. However, it does not explicitly name any alternative tools or provide explicit 'when not to use' guidance.

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