update_work_item_relation_definition

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

No annotations are provided, so the description must carry the full burden. It lists parameters and return type but does not disclose key behaviors such as whether updates are partial (e.g., omitted fields preserved), what happens if the definition_id does not exist, or permission requirements.

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 well-structured with a purpose statement, Args, and Returns. It is concise and front-loaded, with no unnecessary prose.

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 covers purpose, all parameters, and return type, and an output schema is indicated. However, it omits critical update semantics such as partial update behavior, error conditions, and prerequisite conditions, leaving an agent with gaps in how to safely invoke the tool.

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 Args section must compensate. It provides limited added meaning, e.g., 'definition_id: UUID of the relation definition to update' is useful, but most others are tautological re-statements like 'Updated outward label' without deeper constraints.

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 'Update an existing workspace relation definition' with a specific verb and resource. It is distinct from sibling tools like 'create_work_item_relation_definition' and 'delete_work_item_relation_definition'.

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?

Usage is implied by the word 'Update' and 'existing', but there is no explicit guidance on when to use this tool versus alternatives, nor any mention of prerequisites or exclusions.

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