timeweb_get_app_statistics

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

No annotations are provided, placing the full burden on the description. The description only says 'Get resource usage statistics' and does not disclose whether the operation is read-only, what specific metrics are included, time ranges, or any side effects. This is a significant gap for a tool without 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 a single, front-loaded sentence with no wasted words. It directly conveys the core purpose without redundancy.

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?

There is no output schema, so the description should clarify what 'statistics' entails, but it remains vague. It does not mention metrics, time periods, or response format nuances beyond the schema's format parameter. For a statistics tool, this is incomplete context.

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 100%, with app_id and format both documented. The description adds marginal context by mentioning 'PaaS application', but does not enrich parameter understanding beyond the schema. Baseline 3 is appropriate.

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 clearly states a specific verb ('Get'), resource ('resource usage statistics'), and target ('PaaS application'), making its purpose unambiguous. It distinguishes from sibling tools like timeweb_get_server_statistics by specifying 'PaaS application'.

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 description implies the tool is for retrieving statistics on PaaS applications, but does not explicitly state when to prefer it over alternatives or provide exclusions. With sibling timeweb_get_server_statistics, the lack of explicit differentiation makes guidance only implied.

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