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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, fully covering the safety profile. The description adds value beyond that by disclosing the return format (Markdown) and the content scope. No contradictions between description and annotations, and no hidden behaviors (no side effects, no auth requirements) are omitted for a read-only guide fetch.

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 sentence that front-loads the verb and resource, then packs the content topics and output format without any filler. Every element earns its place, and nothing is redundant with the annotations or schema.

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 parameterless, read-only guide retrieval tool with no output schema, the description is quite complete: it names the topics covered and the return format. It could arguably enumerate more detail about the guide's structure, but the main content categories are present and nothing essential for an agent to call it correctly 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 has zero parameters and schema description coverage is trivially 100%, so there are no parameter semantics for the description to clarify. Per the baseline for 0-parameter tools, a 4 is appropriate since nothing is missing; the description focuses appropriately on what the tool returns instead of parameters.

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 states a specific verb (返します/returns) and a precise resource: SealGate integration guide, enumerating its content topics (flow, REST API, browser SDK, server-side examples, errors, pricing) and the return format (Markdown). This clearly distinguishes it from siblings, which are data retrieval (get_app, list_*), action (issue_*, revoke_*), or utility tools.

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?

The description states what the tool returns but gives no explicit when-to-use or when-not-to-use guidance. However, the tool takes zero parameters and returns static documentation, so the use case is largely self-evident, and none of the siblings overlap with guide retrieval, making confusion unlikely. Still, there's no explicit routing or exclusion language.

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