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

Annotations already cover safety (readOnly, idempotent, non-destructive, closed-world), so credit goes to the added semantics: which evidence counts as verified and which does not (inventory rows, aliases, agent callbacks). It doesn't state freshness guarantees beyond 'latest scheduled sweep,' permissions required, or cost of the read.

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, zero waste: the first front-loads the reported fields, the second immediately qualifies the counting rule that governs their meaning. No restatement of the title or schema.

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 params, no output schema and safety carried by annotations, the description must convey what comes back, and it lists the return components plus the counting rule. Minor gap: the shape/format of those counts (per-route vs aggregate) and staleness expectations are left implicit.

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 the baseline is 4; there is nothing for the description to disambiguate. It does not need to explain arguments that do not 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?

A concrete verb, 'Read,' tied to a specific resource and an enumerated payload: catalog size, route variants, verified counts, today's checks and latest sweep. It is distinguishable from per-route siblings like get_route_verification by being a coverage snapshot, but the description never names those siblings or draws the contrast explicitly.

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 text explains what gets reported but not when to choose it over get_route_verification, get_service_overview or request_recheck. There are no exclusions, prerequisites or alternative-routing cues, leaving selection to inference from the title.

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