zernio_sync_ads

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

With no annotations, the description must fully disclose behavioral traits, but it only states it 'syncs ads data to refresh status'. It does not explain side effects (e.g., overwriting local data), required permissions, whether it's destructive, or if it is asynchronous.

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 sentence that is efficient and front-loaded with the action and resource. No extraneous words, every piece of information is necessary.

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?

Given the complexity of a sync operation, the description is too brief. It lacks details on whether it is a full or incremental sync, the outcome on local data, and any prerequisites. No output schema exists to compensate.

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 single parameter 'accountId' is described in the input schema with the same text. Schema coverage is 100%, so the description adds no extra meaning beyond what the schema provides, justifying a baseline score of 3.

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 'Sync' and resource 'ads data', clearly indicating it refreshes campaign and ad status from an external platform. It distinguishes from sibling tools like create, get, or list ads, which have different purposes.

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 on when to use this tool versus alternatives such as zernio_list_ads or zernio_get_ad. It does not explain prerequisites, context, or compare with other syncing or updating tools.

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