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

Annotations already declare readOnly, idempotent, non-destructive, closed-world behavior, so the safety profile is covered. The description usefully adds ordering and page size, but says nothing about the pagination ceiling (page 0-25 at 20 per page) or whether a total count is available, which is the remaining behavioral gap for a paged list tool.

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; ordering and page size come before the per-item payload note. Every clause carries 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, the description must partly carry the return-value burden; it does note that each entry includes its AiSeek page, which helps. It still omits the effective pagination cap and whether results can be exhausted, leaving the agent without a full picture of the result set.

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 100%, with both page and locale fully documented including defaults and bounds, so the baseline is 3. The description's '20 per page' corroborates the page parameter but adds no syntax or format detail beyond the schema.

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 specific resource (newest published changes), an ordering (newest first) and a page size (20 per page), which is more than a restatement of the name. It does not, however, distinguish itself from siblings like search_changes or get_change, so an agent must infer the difference.

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 or when-not-to-use guidance and no sibling is named, despite search_changes, get_change and latest_brief being plausible alternatives. The 'newest first' framing hints at browsing rather than searching, but that is inference, not guidance.

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