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

No annotations are provided, so the description carries the full behavioral burden. It only discloses the output format (Markdown full text) and omits auth requirements, rate limits, error behavior for invalid slugs, and confirmation that the operation is read-only.

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, front-loaded sentence in which every element (verb, resource scope, output format) earns its place. There is no filler or repetition.

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 simple read tool with one enum parameter and no output schema, the description states the return format and basic scope. However, it does not explain the slug parameter or provide usage context relative to siblings, leaving meaningful gaps given the absence of annotations.

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 should compensate, but it only implies a chapter identifier (某一章) without explaining the slug parameter. The enum in the schema lists all valid chapter slugs and is largely self-documenting, partially mitigating the gap.

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 (取得/get), resource (符文戰場新手指南某一章/a chapter of the Rune Battlefield beginner guide), and output format (Markdown 全文). It distinguishes the resource from siblings like get_faq or search_rules by focusing on chapter full text, though it does not explicitly name alternatives.

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 gives no explicit when-to-use or when-not-to-use guidance and does not mention alternatives such as search_rules, get_faq, or lookup_term. The phrase 某一章 implies selecting a specific chapter but does not route the agent among sibling tools.

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