get_performance_trends

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

No annotations are provided, so the description carries the full behavioral burden. 'Get' weakly implies a read-only operation, but the description says nothing about permissions, rate limits, data granularity, or how results are aggregated over the window. An output schema exists, so return shape need not be restated, but the behavioral gaps remain substantial.

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 constraint placed correctly. It is efficient, though its brevity is partly achieved by omitting necessary information rather than by tight editing.

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?

With a 1-parameter tool, a companion output schema, and no annotations, the description should at minimum clarify what 'performance' measures and how the time window is interpreted. It delivers neither, leaving an agent unable to predict what the tool returns or when it is the right choice.

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% — the single 'hours' parameter has no title-level documentation beyond its name and a default of 24. The description's phrase 'specified time period' loosely maps to that parameter but never names it, its unit, or the default, so it adds little beyond 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?

The description states a verb (get) and resource (performance trend analysis) plus scope (over the specified time period), so the general operation is clear. However, 'performance' is undefined — it does not say whose or what performance (server, system, mining throughput) is being analyzed, so an agent cannot confidently distinguish this from analytics-style siblings like get_command_analytics or get_system_health_alerts.

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 statement of when to use this tool, when not to, or which sibling to prefer. The only context given is that it operates over a time period, which is implied usage at best and arguably just restates the schema.

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