users_bulk_reset_traffic

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

Annotations declare readOnlyHint=false and destructiveHint=false, so safety is partly covered, but the description adds nothing beyond them: it does not say what 'reset traffic' actually does to counters, whether it is reversible, or that writes only apply to the listed users. For a mutation tool this is a thin behavioral picture.

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 short sentence with no filler, and the scope qualifier is placed at the end. It is terse to the point of under-specification rather than efficiently informative.

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 bulk mutation with no output schema and no annotation detail, the description should explain the effect of the reset and the batch limits. Neither is present, leaving the agent unable to predict outcomes or size requests confidently.

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?

One parameter with 0% schema description coverage, so the description must compensate. It does identify the parameter semantically ('by User IDs', plural implying an array), but omits the numeric ID type and the 1-500 item bounds enforced by the schema.

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 and resource (bulk reset traffic) plus the scoping mechanism (by User IDs), which weakly separates it from users_bulk_all_reset_traffic. However it never names the single-user sibling users_reset_traffic, so the distinction is left to inference.

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 when-to-use guidance, no prerequisites, and no named alternatives despite three closely related siblings (users_reset_traffic, users_bulk_all_reset_traffic, users_bulk_update). The agent must infer selection rules 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.
