create_work_item_link

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

With no annotations, the description must disclose behavior on its own. It states the return type (Created WorkItemLink object) but does not mention side effects, permission requirements, idempotency, or that this specifically creates a URL link. This is insufficient for a mutation tool.

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 highly concise, front-loaded with the action, and uses a clean Args/Returns structure. Every sentence serves a purpose with no filler.

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 create operation with three parameters and an output object, the description covers the essentials. However, it could be more complete by explicitly noting that this creates a URL link (not a relationship) and clarifying any constraints or side effects. It is adequate but not comprehensive.

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?

Although schema_description_coverage is reported as 0%, the description adds semantic type hints (UUID for IDs, URL for url) that are missing from the schema's generic 'string' type. It does not go beyond the parameter names, but the added types provide some value.

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 ('Create a link') and target ('for a work item'), with a specific resource type. It distinguishes from siblings like create_work_item_relation by focusing on URL links via the url parameter.

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 is given on when to use this tool versus alternatives such as create_work_item_relation. There is no mention of prerequisites, exclusions, or typical use cases.

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