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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety and idempotency profile is covered. The description adds only the routing note about the 'owning node's regional door', and says nothing about pagination, cursor behavior, or limits despite the cursor/limit parameters.

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 no padding; the resource and scope come first. The density of undefined jargon like 'regional door' trades clarity for brevity but the structure itself is efficient.

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 4 parameters at 0% schema coverage and no output schema, the description should at minimum specify date format, identifier type, and pagination via cursor/limit. None of these are present, leaving the agent under-informed for correct invocation.

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, yet it only loosely maps to 'identifier' and 'since'. It never mentions the limit or cursor parameters, gives no date format, and does not clarify what kind of identifier (issuer ID, ticker, etc.) is expected.

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?

The description names a specific resource (dated, URL'd disclosure events) and scopes it to an issuer since a date, which an agent can distinguish from get_record, list_aliases, list_nodes and resolve_issuer. The vague jargon 'owning node's regional door' muddies the delivery mechanism but does not obscure what is returned.

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 statement of when to use this tool versus siblings such as get_record or resolve_issuer, nor any prerequisite (e.g. resolving an issuer first) or exclusion. Usage must be inferred entirely from the name and title.

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