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

No annotations are supplied, so the description carries the full disclosure burden, and it discloses essentially nothing. "Recent" is the only behavioral hint, with no window (24h? 30 days?), no ordering (newest first?), no result cap, and no indication of whether an empty list is a valid outcome.

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?

It is a single short fragment with no filler sentences, which is structurally clean and front-loaded in intent. However, the parenthetical "(maternityuk)" merely repeats the tool name prefix, so the one piece of content it does have is largely wasted on redundancy rather than on the recency window that matters.

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, no annotations, and no parameters, this description is the sole source of information about the tool, and it supplies one vague clause. An agent has no way to know what a changelog entry contains, how far back "recent" reaches, or how to interpret results, which is inadequate even for a simple zero-argument tool.

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 is an empty object with zero parameters, so there is nothing for the description to explain. Baseline for a zero-parameter tool applies; the only unaddressed question is whether an implicit time window exists, which is a behavioral rather than parameter concern.

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?

"Recent verification changelog" identifies the resource type and the parenthetical identifies the domain, and the sibling pattern ({domain}_changes vs _get_fact/_list_facts) makes the family role inferable. But it is a noun phrase with no verb, and "verification changelog" is unexplained jargon — an agent cannot tell whether this lists changed facts, re-verification timestamps, or source updates.

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 at all — nothing says to call this before or instead of maternityuk_list_facts or maternityuk_get_fact. The relationship implied by the sibling naming (changes = deltas since a point, list_facts = current snapshot) is left entirely for the agent to guess.

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