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

Annotations already declare readOnlyHint=false, openWorldHint=false and destructiveHint=false, yet the description adds material context: each call consumes one token, an XBOSS job is created and its result stored, and the call is explicitly 'not purely read-only' even though nothing in the agency's source data is changed. That reconciles the non-read-only annotation with the actual side effect, which is exactly the kind of disclosure annotations cannot provide; it stops short of describing the response payload.

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 prerequisite and payload description are well front-loaded, but the idempotency block runs five sentences for a single optional parameter and repeats itself ('Without it, calling again remains a new request'). The closing sentence about agency data changes per tool is vague filler that adds no decision-relevant information.

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?

With no output schema and only two parameters, the description needs to carry the return contract, and it only partly does so: it says the caller receives an ordering rule and 'five items' without enumerating those five items or their shape. Token cost and job-creation side effects are covered, so nothing critical is missing for invocation, but the return contract remains under-specified.

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 coverage is 100%, so the schema already documents both parameters, which sets the baseline at 3. The description does add real meaning for request_idempotency_key (generate before the first request, reuse only to recover a lost response, new key for a new execution, unavailable to anonymous calls, distinct from a provider-specific key), but it says nothing about account_link_id behavior beyond implying the linked account is used.

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 states concretely what the tool returns: the order/sequence for picking a single electronic notice from search results and the five items used when picking it, and that the rule lives on the server and contains no notice content. That is a clear verb+resource statement, but it does not name or distinguish itself from siblings such as __search_options, __select, or __detail, so an agent must infer where it sits in the workflow.

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?

A concrete prerequisite is given ('REQUIRES prior nhis_edi__session__login call with same account_link_id'), which is genuinely actionable. However, there is no guidance on when to call this versus the sibling search_options/select/detail tools, and no exclusion or ordering advice beyond the login precondition.

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