Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations are provided, so the description carries the full burden of behavioral disclosure, but it only states that the tool 'routes' — nothing about whether it executes the task, dispatches to external services, has side effects, requires authentication, or returns a routing decision versus a result. The single vague verb does not meaningfully disclose behavior.

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 brief, but the 'Task Router:' prefix wastes words restating the tool name, and the brevity reflects under-specification rather than deliberate conciseness. A router claiming to dispatch across a massive service ecosystem requires substantially more content to be useful.

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 tool that routes tasks across what appears to be a huge ecosystem of services, this definition is radically incomplete: no annotations, no output schema, three optional generic parameters, and no mention of available target services, routing criteria, response format, or error behavior. An agent cannot correctly select or invoke this tool.

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?

While schema coverage is nominally 100%, every parameter description is a tautology ('task: Task to process', 'input: Input to process', 'query: Query to process'), and the three parameters appear semantically interchangeable with no guidance on which to populate — and all are optional. Neither the schema nor the description adds real meaning, which is actively unhelpful for invocation.

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 'Route a task to the right service' essentially restates the tool name (task-router) with a generic verb, and the 'Task Router:' prefix is a direct repetition of the name. It does not define what counts as a task, what services are routable, or how the routing decision is made, and it fails to distinguish the tool from the sibling service_discovery or the hundreds of specialized x402-* 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 gives no conditions for when to invoke this router versus calling a specialist tool directly, and it names no alternatives or exclusions. Given the enormous sibling list filled with purpose-specific tools plus a service_discovery tool, an agent has no basis for deciding when routing is the correct choice.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
