Get Series Details

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only says 'Get series by ID' and does not elaborate on return format, error handling, authorization requirements, or what fields are included, leaving significant behavioral ambiguity.

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 with no wasted words. It is appropriately front-loaded and easy to parse.

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 simple single-parameter get-by-id tool, the description is minimally viable, but given the absence of an output schema and annotations, it lacks detail on return structure or possible variations. It is sufficient for a trivial fetch but leaves questions about the response and domain context.

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 description coverage is 0%, so the description must compensate. 'By ID' clarifies that the 'id' parameter is the series identifier, which adds some semantic meaning beyond the raw schema. However, it does not explain the nature of the ID or any constraints, so compensation is only partial.

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 'Get series by ID' uses a specific verb and resource, making it clear the tool fetches a single series by its identifier. It distinguishes itself from list_series (which lists all series) implicitly, but does not explicitly differentiate from get_series_metadata, which is a closely named sibling.

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?

There is no guidance on when to use this tool versus alternatives such as list_series or get_series_metadata. The description simply states the function without any context on selection criteria, prerequisites, or exclusions.

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