Get Service Uptime Chart

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, covering the safety profile. The description adds nothing beyond that — no note on what the chart contains, granularity, default time window, or whether missing data yields empty results, despite openWorldHint implying external dependency behavior.

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 single-sentence description is trivially short and front-loaded, but its brevity stems from under-specification rather than efficiency. It wastes no words, yet conveys almost no information.

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?

An output schema and annotations exist, so return-value explanation is not strictly required, but the description still omits the meaning of `period`, the chart's time semantics, and how it differs from adjacent chart tools. For a tool whose only distinguishing feature is 'uptime chart', that leaves meaningful gaps.

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 coverage is 50%: the `id` parameter is richly documented with UUID/slug formats and an explicit note that there is no `service_id` argument. The `period` parameter has no description in either schema or description, and the description does not compensate at all — it never mentions timeframe or its accepted values.

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?

Tautological: description restates name/title.

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?

There is no when-to-use, when-not-to-use, or alternative-tool guidance. The only implied usage is that this returns a chart of uptime for a service, which the name already conveys; sibling chart tools are never mentioned as alternatives.

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