get_series

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

The description aligns with the readOnlyHint annotation, confirming a read-only operation. It does not add behavioral context such as error handling, authentication requirements, or response format details, but the annotation already covers the safety profile. With annotations present, the bar is met without extra disclosure.

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 is front-loaded with the action and resource. Every word earns its place; there is no redundancy or filler.

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 retrieval tool with one parameter, an output schema, and a read-only annotation, the description is sufficient. It covers what the tool does and how to invoke it. The lack of usage guidelines or edge-case details is acceptable given the low complexity, though it could be enhanced.

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%, and the description adds minimal semantic value beyond the parameter name. 'by ID' merely restates that series_id is an identifier without explaining the ID format, source, or examples. The description fails to compensate for the absent schema documentation.

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 the specific verb 'Get' with the resource 'series details and metadata' and explicitly states 'by ID', clearly defining the action and scope. This distinguishes it from sibling tools like search_series or get_series_collections, which serve different purposes.

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?

Usage is implied: when you have a series ID and need details, use this tool. However, there is no explicit guidance on when to use alternatives or exclude other tools, such as search_series for discovery. No exclusions or alternative named.

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