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

With no annotations, the description carries the full burden and does reasonably well: it discloses that the call is read-only inspection, authenticated, free (no cost incurred), scoped to owned routes, and that the payload includes attempts and payment exposure. It stops short of stating what happens on a non-owned/unknown route_id or any rate limits.

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?

A single tightly-packed sentence with zero waste; the free/authenticated/ownership qualifiers and the returned content are all front-loaded before any elaboration would be needed.

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 one-parameter read tool with no annotations and no output schema, the description gives enough to call it correctly and preview the response contents (attempts, payment exposure). Only the error/not-found behavior is left implicit, which is minor here.

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 coverage is 100% for the single route_id parameter, so the baseline is 3. The description adds one meaningful constraint beyond the schema — the route must be owned by the caller — but does not otherwise enrich the UUID semantics.

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 specific verb (inspection) and resource (a route) with an ownership scope (owned by the calling agent), so the agent knows exactly what it retrieves. It does not, however, differentiate itself from the sibling get_route_task, which an agent could easily confuse it with.

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?

"Owned by the calling agent" and "free" imply the context in which this applies (read-only introspection of your own route rather than someone else's), but there is no explicit when-to-use/when-not guidance and no named alternative such as get_route_task or continue_route.

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