nexo_closure_link

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

With no annotations, the description must fully disclose behavioral traits. It only says 'Link' without explaining whether the link is created or updated, what side effects occur (e.g., changes to closure state), or any access requirements. Critical transparency is missing.

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 sentence, which is concise, but it lacks important details that could be added without excessive length. It is front-loaded with the verb and target list, which is good, but still feels underspecified.

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?

Given the lack of output schema and annotations, the description should provide more context about return values, error conditions, and prerequisites. It only explains the basic action, leaving the agent with many unknowns for invocation.

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 lists target types in the description but does not explicitly map them to the 'link_type' parameter. The meaning of 'item_id', 'link_id', and the default 'relation' value are not clarified beyond their names.

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 action ('Link') and the resource ('a closure item') and lists specific target types ('task, workflow, followup, outcome, or learning'), distinguishing it from nearby closure tools that perform different actions like close, get, or verify.

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 guidance on when to use this tool versus alternatives such as nexo_closure_close or nexo_closure_item_get. There is no mention of prerequisites, context, or situations where linking is inappropriate.

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