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

No annotations are provided, so the description carries the full burden of explaining behavior. It only describes the data contents, not what the tool returns, whether it is read-only, how pagination works, or how the 'result' parameter affects the response. This leaves important behavioral expectations undocumented.

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?

The description is very brief and economizes words, which is good, but it is more of a fragment than a structured definition. It conveys useful identifying information yet could include a short sentence about parameters or filtering without becoming bloated.

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 parameter descriptions, the description leaves several operational gaps: what the return format is, how the result filter works, and whether limit has any upper bound. The tool is simple, but even simple tools need at least one clarifying sentence beyond a data-content listing.

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 compensate, but it only mentions 'result' as a data field and makes no clear connection to the 'result' input parameter. The 'limit' parameter is not explained at all, leaving the agent to guess whether it controls page size, result count, or something else.

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 identifies a specific resource type ('HKEX listing hearing records') and enumerates the key data contained (company, date, result, market), which clearly distinguishes it from sibling tools like get_listing_day_close or get_corporate_actions. It lacks an explicit verb like 'get' or 'list', but that is somewhat supplied by the tool name, making the purpose understandable.

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 guidance about when to use this tool versus any of the many sibling tools, nor any indication of filters, common use cases, or exclusions. The intended use is only implied by the domain-specific name and one-line description, which is insufficient for disambiguating among the large sibling set.

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