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

No annotations are supplied, so the description carries the full behavioral burden, and it discloses almost nothing: no read-only vs mutating statement, no permission or shop-membership requirements, no indication of what is returned or whether the settings are shop-wide. The only behavioral signal is the enumerated subject matter, which is topic description rather than operational transparency.

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 compact sentence with the domain front-loaded ('The shop's lead rules') and the three rule areas enumerated crisply; there is no filler. It loses a point because the compressed colon-list construction is what creates the read/write ambiguity — a single added verb would have cost no length.

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 the description does not need to detail return values, and the rule areas it names plausibly mirror the response shape. What is still missing for a shop-scoped settings tool is the read-vs-write framing and any note about permissions or shop scope. The description is adequate to guess at the tool's domain but not adequate to call it confidently.

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 schema has one parameter, shop_id, at 0% description coverage, and the description never mentions it or clarifies whether it is the shop whose rules are fetched. However, shop_id is a self-evident UUID selector for a shop-scoped tool, so the omission is low-cost rather than dangerous. Baseline 3 is appropriate for a single obvious parameter the description does not actively obscure.

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 is a noun phrase listing the lead-rule topics (first-reply window, after-hours behavior, flag/skip lead types) but never supplies a verb, so it does not say whether the tool reads or writes those rules. The sibling list contains requests_setLeadSettings, which makes the read/write distinction consequential, and this description does not resolve it. The subject matter is specific and distinguishable from other requests_* tools, but the missing action keeps it at vague-purpose level.

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 when-to-use guidance, no precondition, and no mention of an alternative. The obvious alternative, requests_setLeadSettings, exists as a sibling but the description neither names it nor explains which one an agent should reach for when it wants to change a rule versus inspect one. The agent must infer routing entirely from the tool names.

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