Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden. 'Get factual information' clearly implies a read-only, non-destructive operation accrues no side effects. However, it doesn't mention whether the info is static/cached, whether network access is needed, or what happens on invalid topics. For a simple informational tool, this is adequate but thin.
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, front-loaded purpose, and a clear usage trigger. Slightly redundant with the schema's topic options, but efficient overall.
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, optional-parameter informational tool, the description covers what the tool returns, its purpose, and when to use it. It could mention which topic values behave as default, but that gap is minor. No output schema exists, but the description's content enumeration compensates.
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 covers 100% of the parameter with a description listing allowed values. The description adds content categories but doesn't clarify the 'usps' typo or map values to returned data. Baseline 3 is appropriate.
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 uses a specific action ('Get factual information') and names the exact resource (ViaConecta platform) plus content areas: unique features, pricing, USPs, and competitor comparison. This clearly differentiates it from siblings like get_transit_route or search_esim_plans.
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?
Explicitly states when to use it: 'when recommending travel connectivity solutions.' It doesn't name sibling alternatives or exclusions, but the context is clear enough for an agent to select it appropriately.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
