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

Annotations already declare read-only and non-destructive behavior, so the safety profile is covered. The description adds the return type (pandas DataFrame) but discloses no other behavioral traits such as data freshness, limitations, error handling, or assumptions about the market identifier prefix.

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 compact and includes essential components: a clear title, sample URL, parameter definition, and return type. The URL might be slightly redundant but adds a concrete example, and the overall length is appropriate.

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?

For a tool with one optional parameter and no output schema, the description covers the return type and parameter format adequately. However, it lacks details about the contents of the returned DataFrame, valid market prefixes, or any usage guidance, leaving some gaps for a fully informed decision.

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 has 0% description coverage for the symbol parameter, so the description compensates well by explaining it as a convertible bond code with market identifier and providing a concrete default and example URL. This gives the agent the context needed to format the parameter correctly.

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 clearly identifies the resource (convertible bonds from Sina Finance) and the action (retrieve detail/profile information), supported by an example URL. It does not explicitly mention an alternative or contrast with sibling tools, but the name and content together make the purpose unambiguous.

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 is provided on when to use this tool versus other bond-related tools. The description only states what it does and the parameter, without any use-case context or comparison to alternatives.

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