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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds ordering (newest first) and recency scoping, but says nothing about how 'recent' is bounded, whether the result is capped, or pagination — meaningful gaps for a history endpoint.

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 sentence with zero filler; the scope constraint and ordering come first. Nothing is repeated from the title or schema.

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 two-parameter read tool with annotations covering safety and no output schema, the description is close to sufficient but leaves the limit parameter and the meaning/shape of a 'check' record unexplained. Adequate, not complete.

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 description coverage is 0%, so the description must carry parameter meaning and largely does not. 'One asset' loosely maps to the required id, but the limit parameter is never mentioned — no default, no indication of what it limits (checks returned) — and id's expected format is left entirely to the schema's maxLength constraint.

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?

States the resource precisely — expiry check history for a single asset — and distinguishes it from sibling get_asset/list_assets by making clear it returns checks, not the asset itself. It also discloses ordering (newest first). No explicit verb ('returns'), but the resource and scope are unambiguous.

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?

Usage is only implied: an agent can infer this is for inspecting an asset's past expiry checks. There is no explicit when-to-use vs get_asset or list_expiring, and no guidance on choosing a limit value or what happens with the default.

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