shorten_url_batch

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

Lacks annotations and fails to disclose crucial behavioral traits like maximum batch size, error handling, or processing behavior. The description carries full burden but adds minimal behavioral context.

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?

Extremely concise at two sentences, but the brevity sacrifices informational value. Could be slightly expanded without losing conciseness.

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, the description omits critical context for a batch operation such as result format, error handling, and any operational limits. Incomplete for effective use.

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?

Adds meaning for the 'urls' parameter by specifying delimiters, but does not describe 'collection_name' or 'tags' at all. With 0% schema description coverage, this is insufficient.

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?

Clearly states it shortens multiple URLs at once, with input format details. However, it does not explicitly distinguish from the sibling 'shorten_url' tool, which presumably handles single URLs.

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?

Provides no guidance on when to use batch vs individual shortening, no prerequisites, and no mention of alternatives. The description only explains input formatting.

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