get_system_overview

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

With no annotations, the description must convey behavioral traits. It discloses that it collects read-only system information and returns a formatted report, which implies no side effects. However, it does not explicitly state it is non-destructive or note any permissions/connection behaviors, so it is adequate but not rich.

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 compact and well-structured: a clear opening sentence, a concise list of collected metrics, a usage note, and a clear Args/Returns format. Every line adds value and there is no padding or 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?

For a tool with one optional parameter and an output schema, the description covers all essential aspects: purpose, scope, parameter semantics, and return value. It does not mention potential failures or limitations, but these are not critical for such a straightforward read-only overview within a rich sibling 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?

The input schema has zero description coverage, but the description fully explains host_name: it comes from SSH_HOSTS config and defaults to the default host if omitted. This adds meaningful semantic context beyond the schema's raw type definition, earning a strong score.

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 specific verb ('Get') and resource ('comprehensive system overview') and lists the exact data collected (hostname, OS release, etc.), distinguishing it from sibling tools like get_cpu_info or get_memory_info by explicitly positioning it as a holistic overview.

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 phrase 'Best starting point for system analysis' clearly suggests when to use this tool, implying that for deeper specifics, one would turn to more specialized sibling tools. It gives a clear context but does not explicitly name alternatives or exclusions, so one point is deducted.

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