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

The description states the output categories (TVL, audits, risk grade), which gives some idea of the returned data. However, with no annotations, it does not explicitly state that the operation is read-only, nor does it mention limitations or caveats (e.g., supported protocols, update frequency). This is moderate disclosure but lacks depth.

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 a single concise fragment that clearly communicates the purpose and key output fields in a few words. It front-loads the core concept and includes examples with no superfluous text.

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?

Given the lack of an output schema and annotations, the description is too brief. It omits usage guidance, detailed parameter semantics, and return structure. It does not explain what 'risk grade' means or whether multiple protocols can be queried simultaneously. The ellipsis suggests more protocols but does not enumerate them.

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 only parameter 'protocol' is a bare string with no schema description. The description provides example values (SaucerSwap, Stader, HeliSwap), offering a clue about accepted inputs. This partially compensates for the 0% schema coverage, but it does not specify format, case sensitivity, or how to handle unknown protocol names.

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 the resource (protocol health) and specifies the data categories (TVL, audits, risk grade). It names example protocols to clarify scope, but lacks an explicit verb like 'get' or 'retrieve'. It distinguishes from siblings such as hbar_protocol_list by focusing on health metrics.

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 alternatives like hbar_protocol_list or hbar_defi_yields. There is no mention of use cases, exclusions, or preferred context, leaving the agent without decision-making support.

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