hb_route_stats

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: no read-only assurance, no auth requirements, no indication of whether stats are cumulative or per-session, and no return shape. For a no-annotation tool this is a significant gap.

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?

It is a single short sentence with no padding, which is good, but the brevity comes at the cost of under-specification rather than genuine economy. Nothing is front-loaded because there is only one clause.

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 annotations and no output schema, the description is the only source of information about what this tool returns, and it does not describe the statistics, their format, or their freshness. An agent could call it, but could not anticipate the result.

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 takes zero parameters, so there is nothing for the description to add beyond the empty schema. Baseline of 4 applies; nothing is missing or misleading on this dimension.

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?

It names a verb (Get) and a resource area (routing statistics and learning progress), which loosely separates it from hb_route_select and hb_route_evaluate. But 'routing statistics' and 'learning progress' are vague — it never says what is measured, over what window, or in what scope, so an agent cannot tell exactly what it retrieves.

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?

There is no statement of when to use this tool versus hb_route_select, hb_route_evaluate, or any sibling. The agent must infer that a stats getter is for observation rather than route selection, with no explicit trigger condition or exclusion.

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