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

The description adds a useful behavioral detail not otherwise evident: there is no /bulk/ endpoint, and the request is a bare JSON array sent to the normal create path. This is valuable beyond the annotations, which are all generic false flags. However, it does not disclose whether creation is atomic, what happens on partial failure, or any auth/rate-limit considerations, so the behavioral picture is incomplete.

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?

Two sentences, front-loaded with the primary purpose, followed by a concise and relevant implementation caveat. Every word earns its place and there is no filler or redundancy.

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 one-parameter bulk-create tool, the description plus schema is sufficient to attempt a call. But because there is no output schema and annotations are uninformative, the lack of any mention of response shape, partial success, or failure behavior is a noticeable gap. The "normal create path" hint partially compensates but does not fully answer what the agent should expect.

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% and the description adds no parameter-level meaning beyond the name "links". The JSON schema itself is reasonably explicit, but the rubric requires the description to compensate when coverage is low. It does not explain item format, required fields beyond the schema, or relationship to the single create payload.

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's function: "Create several links in one call." It also adds an implementation detail, "Sends a bare JSON array to the normal create path," which helps distinguish this bulk variant from the single-link sibling split_create_link. However, it does not explicitly name or contrast the sibling, so it stops just short of full differentiation.

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?

"Create several links in one call" gives clear contextual guidance: this tool is for bulk creation, not single creation. It does not explicitly say "use split_create_link for one link" or describe when not to use this tool, but the stated purpose implies the right usage condition. A short exclusion note would make it fully complete.

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