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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so safety is settled. The description adds real scope information beyond that — the response includes concept markdown revisions and relations, not just node identities — but says nothing about response size, whether a whole graph can be large, or whether revisions are expanded or merely referenced.

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?

One front-loaded sentence with no filler; the resource and payload contents arrive in the order an agent needs them. It is arguably a touch terse for a tool that returns a whole graph, but nothing is wasted.

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?

Complexity is low (one required string parameter, no nesting), and with no output schema the description does the necessary work by naming what comes back. The remaining gap is that it does not characterize the shape or scale of the returned graph, which would matter for an agent deciding whether to call this or a narrower 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?

Only one parameter exists and schema description coverage is 100%, so the schema already documents work_item_id. The description adds no formatting, scoping, or ID-source guidance, which is acceptable at this baseline but is no more than minimum viable.

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 pairs a specific verb ("Get") with a specific resource ("the complete graph for a work item") and enumerates what the payload contains: concept markdown revisions and relations. That distinguishes it from list/get tools returning just concepts or just work item fields, though it never names the closest siblings (get_work_item_concepts, traverse_pspp_graph, run_graph_query).

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?

There is no explicit when-to-use statement, no condition for choosing this over get_work_item_concepts or traverse_pspp_graph, and no note about call cost or size. The word "complete" hints at bulk retrieval, but the agent must infer that from a single adjective.

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