v1.17.5Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations present, the description carries full burden. It discloses that the taxonomy is 'public' and 'top-level', which tells the agent no auth is needed and this is a shallow taxonomy rather than a deep tree. It does not describe output formatting or pagination, but for a simple 0-param read the disclosure is adequate but minimal.
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 short sentences with no filler. The core verb+resource is front-loaded, and the second sentence earns its place by clarifying scope and linking to the headlines endpoint.
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 zero-parameter, no-output-schema tool, this description is complete. It tells the agent what the tool returns (the section taxonomy), its level (top-level), and its relationship to sibling tools (used by headlines). Nothing critical 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, so the baseline of 4 applies. The description has nothing to add beyond the schema, and none is needed.
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 opens with a specific verb+resource ('Get PC Gamer sections') and adds scope ('top-level editorial taxonomy'). It distinguishes itself from sibling tools like pcgamer_headlines and pcgamer_news by explaining its output is the taxonomy used by the headlines endpoint.
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: it is meant to supply the section taxonomy that feeds the headlines endpoint. This signals when an agent should call it (to understand section names for headlines filtering). It does not explicitly enumerate alternatives or exclusions, but for a zero-parameter tool this is sufficient.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
