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

With no annotations, the description carries the full behavioral burden and does not meet it. "Recent" implies a recency window that is never defined, and nothing is said about ordering, volume, pagination, or whether entries include timestamps or diffs.

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 short phrase with no filler, front-loaded with the key concept. It is efficient but borders on under-specification given the ambiguity of "verification changelog."

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?

There is no output schema and no annotations, so the description is the only source of truth about what comes back — and it says nothing about the shape, size, or time scope of the changelog. For a changelog tool, the return structure is the essential information and it is missing.

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 tool takes zero parameters, so there is nothing for the description to disambiguate. Baseline 4 applies; the only gap is not stating that the call is parameterless and returns a fixed recent window.

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 (dismissaluk)" names a resource and a domain, but "verification changelog" is ambiguous — it never says what is being changed or verified (facts? sources? rules?). Sibling names like dismissaluk_get_fact and dismissaluk_list_facts are concrete; this one requires inference to understand it returns a list of recent 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 guidance on when to call this versus dismissaluk_get_fact or dismissaluk_list_facts. An agent cannot tell whether this is the entry point for freshness checks, an audit log, or a supplement to fact retrieval.

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