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

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is covered. The description adds value beyond those annotations by disclosing page ordering and emphasizing that the returned section uuids are the reference for later reordering; no contradiction is present.

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?

Two short sentences, front-loaded with the primary purpose and followed immediately by the one critical usage caveat. There is no filler; every sentence carries operational value.

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 zero-parameter, annotation-covered read-only tool, this is nearly complete: it provides the output order, the reordering workflow, and references the uuid needed later. It does not spell out the return payload fields or explicitly distinguish from split_list_predefined_sections, but those are minor gaps that do not block correct 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?

The tool has zero parameters, so the schema covers 100% by construction. The description still adds useful context by implying that returned sections carry a uuid that reorder operations depend on, but there is no parameter to explain further.

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 identifies the operation ('List sections') and a meaningful qualifier ('in page order'), so an agent understands what the tool returns and how it is ordered. It does not explicitly contrast itself with the sibling split_list_predefined_sections, so it stays just short of full sibling differentiation.

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 second sentence gives an explicit, actionable when-to-use rule: 'Always call this before reordering' and explains why by tying reorder moves to another section's uuid. It does not mention alternatives or cases where it should not be used, but for a read-only listing tool that is a minor gap.

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