links_batch_create

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

With no annotations, the description carries full burden. It discloses atomicity (if any record fails, none are created) and a key constraint (paid-plan only). It does not cover rate limits, idempotency, or response format, but the disclosed traits are critical for correct invocation.

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 extremely concise: two sentences plus a tag line. Every word adds value (atomicity, paid-plan). No unnecessary fluff.

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?

The description explains core behavior and constraints but lacks information about the return value (e.g., what is returned upon success) and does not describe the nested 'targets' parameter structure in plain language. For a batch creation tool, return details are helpful. However, atomicity and plan restriction are well-covered.

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 only 33%, so the description should compensate. It explains the overall action ('Link one entity to multiple entities') which clarifies the relationship between entityA and targets. However, it does not add detail about the 'targets' array structure, entity types, or ID formats beyond what the schema provides.

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 purpose: 'Link one entity to multiple entities at once'. It distinguishes from the sibling tool links_create (singular) by being a batch operation. The atomicity detail adds specificity.

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?

The description implies usage for batch linking with atomicity, and explicitly calls out the paid-plan restriction (free-plan gets 403). However, it does not explicitly compare to links_create or other alternatives, leaving some ambiguity about when to use the singular version.

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