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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is covered. The description adds the ordering and recency scope, but says nothing about how far back it reaches, default result size, or pagination — meaningful gaps for a list-style read.

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?

Very short and front-loaded, with the recency/ordering constraint stated immediately. The bilingual duplication is defensible for a locale-aware tool, though it repeats the same content rather than adding detail.

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 parameterized read tool with no output schema and 0% parameter coverage, the description leaves too much unstated: what a 'change record' contains, default limit, locale behavior, and time coverage. An agent can call it, but cannot predict the result shape.

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?

Two parameters (limit, locale) with 0% schema description coverage, so the schema supplies no semantics and the description must compensate — but it never mentions either parameter. It does not clarify that limit caps results or how locale affects returned content.

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 a clear verb+resource: retrieve recent data change records, with an ordering qualifier (newest first). It is understandable on its own, though it does not differentiate from sibling tools — which is acceptable here since the siblings (offers, coding clients) are unrelated domains.

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?

Only 'recent' and 'newest first' hint at when to use it. There is no guidance on what window counts as 'recent', no prerequisites, and no mention of alternatives or related tools for reaching older change history.

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