-}New value: +nullDoes the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false. The description adds that there is 'no payment or provider call', which is useful extra context beyond the annotations, but it does not describe return behavior or other operational details.
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 compact sentence with the read-only nature front-loaded. It wastes no words, though the extreme brevity leaves important context unstated.
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?
With no output schema and a non-obvious resource name, the description should explain what a discovery call returns. It only states safety properties and omits return semantics or usage context, leaving an agent unable to fully understand the tool's outcome.
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 per the baseline rule parameter semantics is 4. The description correctly does not discuss parameters because none exist.
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?
States a read-only discovery operation for the named resource, which gives a verb+resource. However, 'discovery' is vague and the description does not explain what is being discovered or what the tool returns, making it only minimally distinguishable from siblings beyond the no-payment note.
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 mentions 'no payment or provider call' but does not say when to use this tool versus the invoke_* sibling or when not to use it. No explicit alternatives or prerequisites are given.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
