Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. It discloses data source (local snapshot of official documents), response default, opt-in behaviors, token-saving rationale, and a 15000-character truncation warning, offering substantial behavioral context beyond the schema.
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 two sentences that efficiently front-load purpose and then detail usage nuances. Every clause adds value—no filler or redundancy.
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?
Despite lacking an output schema, the description explains default response fields (字號/日期/爭點/解釋文), opt-in reasoning/opinions, and truncation warning. It covers the tool's full behavior adequately for an agent to use correctly.
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 coverage is 100%, but the description adds critical semantics: the priority relationship between keyword and include parameters, why to prefer keywords (省 token), and full-text truncation behavior. This significantly enriches the bare schema descriptions.
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 states the tool's function: 取得釋字 or 憲判字 content, with specific scope (第 1-813 號, 111 年起) and resource type. It also lists default return fields, distinguishing it from sibling search/citation 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 provides clear context: this is for direct retrieval of specific interpretations, with parameter-level usage guidance (prefer keyword snippets, use include_* only when necessary). However, it doesn't explicitly mention alternatives or exclusions relative to sibling tools like search_taiwan_interpretations or get_taiwan_interpretation_citations.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
