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

Annotations already indicate a non-read-only, non-idempotent mutation, and the description adds a meaningful behavioral constraint: the tool operates on route-class observations and rejects raw sensitive data. This is useful context beyond the structured fields and does not contradict the annotations.

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 two sentences with no filler, and the core verb/resource is front-loaded. The privacy constraint in the second sentence is a critical usage rule that earns its place.

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 7-parameter submission tool with no output schema and no property descriptions, this description is too thin: it omits what each parameter means, what payload shape is expected, and what happens after submission. The privacy rule is helpful but does not make the tool safely callable by an agent.

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 description coverage is 0%, but the description does not explain any of the seven properties such as routeType, targetClass, outcome, failureClass, or latencyBucket. It only states a general privacy restriction, leaving the meaning of enums and required fields to be inferred from parameter names. This fails to compensate for the missing schema descriptions.

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 verb ('Submit') and a specific resource ('privacy-preserving route-class observation'), clearly conveying this is a reporting/mutation tool. It is somewhat distinguishable from the preflight/feed siblings by the word 'observation', though it does not explicitly name a sibling to avoid confusion.

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?

No guidance is provided about when to use this tool instead of traffic_preflight, delegation_preflight, or get_agent_traffic_feed. The only operational rule is the privacy constraint ('Raw URLs, payloads, headers, secrets, tokens and agent identifiers are not accepted'), which is not a usage-selection criterion. The agent must infer when this tool is appropriate from the name alone.

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