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

With no annotations, the description carries the full burden. The only behavioral fact given is sort order (newest first); nothing about pagination, result limits, whether it is read-only, or on whose behalf (authenticated homeowner) the list is scoped. The "your" framing is doing unstated work.

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?

A single front-loaded fragment with zero filler, and the ordering is stated up front. It is arguably too terse rather than padded, but no sentence 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?

An output schema exists, so return shapes needn't be described, and no params means no call-time complexity. What is still missing is the scope question: whether results are limited to the calling homeowner's requests and whether the list is paginated — meaningful gaps for a portal-facing list.

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 takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. Schema coverage is 100% and the empty object leaves no ambiguity.

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?

"Your customer requests" identifies the resource and "newest first" the ordering, so the agent knows it is a list operation. But the verb is only implied by the tool name and the phrase "your customer" is ambiguous — it doesn't clarify whether this is the homeowner-portal-scoped view versus the shop-side requests_list sibling, which is the exact confusion an agent would have here.

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?

No when-to-use guidance and no mention of alternatives, despite many plausible siblings (requests_list, requests_get, homeowner_getRequest, requests_pipeline). The agent gets no signal about when this portal-scoped list is the right call versus the general requests_list.

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