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

No annotations are provided, so the description carries the full burden. It states 'Update a work item' which implies a mutation, but doesn't disclose behavioral traits like required permissions, whether updates are partial or full, side effects, error conditions, or response format. This is inadequate for a mutation tool with zero annotation coverage.

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 with just one phrase, front-loaded with the context and action. There is no wasted text, making it efficient for quick scanning.

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 complexity (3 parameters with nested objects), lack of annotations, and no output schema, the description is incomplete. It doesn't provide enough information for an AI agent to understand how to properly invoke this tool, what to expect in return, or the implications of the update operation.

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?

The description adds no parameter semantics beyond what the input schema provides. With 67% schema description coverage (parameters like 'organizationId' and 'workItemId' are documented, but nested fields lack descriptions), the baseline is 3. The description doesn't compensate for the coverage gap by explaining the 'updateWorkItemFields' object or its nested properties.

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 ('Update') and resource ('a work item'), and the '[Project Management]' context helps scope it. However, it doesn't differentiate from sibling tools like 'update_application' or 'update_sprint', which are also update operations in the same domain.

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 provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., needing an existing work item), exclusions, or comparisons to similar tools like 'create_work_item' or 'get_work_item'.

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