Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations provided, but description notes 'FREE' and lists output contents. Sufficient for a read-only catalog tool, though could mention no destructive effects or authentication needs.
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?
Two sentences; first gives essential information about output, second gives usage advice. No extraneous words, efficiently front-loaded.
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?
No output schema, but description enumerates the types of data returned (countries, IDs, descriptions, freshness, URLs). Combined with usage hint, fully informs agent of what to expect and how to use.
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?
No parameters in schema (0 params), so description doesn't need to add parameter info. Baseline of 4 applies as schema coverage is 100%.
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 explicitly states 'Catalog of all asiaref reference-data series' and lists what it provides, distinguishing it from sibling tools like get_series which likely target a specific series.
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?
Clearly instructs 'Call this first to discover what data exists,' giving a preferred usage order. Does not explicitly mention when not to use, but context with siblings implies alternatives.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
