get_recently_added

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

No annotations provided, so the description must carry the burden. It states it returns recently added items and supports filtering, but does not disclose behaviors like rate limits, maximum items, ordering, or whether all libraries are included by default. The description is minimal for a read operation.

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 concise with two sentences. The first sentence states the action, and the second adds clarification on filtering. No redundant text, effectively 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 two optional parameters and an output schema, the description covers the basic functionality but lacks details on pagination, ordering, and the default behavior of including all libraries. It is adequate for a simple tool but could be more complete.

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. It explains the library_name parameter by giving examples but does not describe the limit parameter beyond its default in the schema. The description adds some value for library_name but is insufficient for limit.

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 that the tool retrieves recently added media from Plex, with an optional filter by library name. It effectively conveys the verb and resource, but does not explicitly mention chronological ordering, which is implied. It distinguishes from siblings like search_media and get_library_contents.

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 explicit guidance on when to use this tool over alternatives. The description implies its use for recently added items, but does not mention when not to use it or provide comparisons with sibling tools like get_libraries or get_library_contents.

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