System Get Settings Snapshot

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

Annotations declare readOnlyHint and idempotentHint, which covers the safety profile, but the description adds no behavioral context beyond that. It does not explain what a settings snapshot contains, whether it is expensive, or any practical implications of calling it.

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 short but under-specified. It spends its only sentence restating the tool name and platform rather than providing useful information, so it is not appropriately concise; it is simply minimal.

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?

Despite having no parameters and an output schema, the description is too vague for an agent to understand what this tool returns or how it relates to sibling snapshot/status tools. Key context about the snapshot's scope and purpose is missing.

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 tool has zero parameters and an empty input schema, so there is no parameter semantics burden on the description. The baseline of 4 applies because nothing needs to be explained.

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 only restates the tool name and says it is a 'Delegated Apple domain tool' exposed through Apple-Tools-MCP. It does not state what the tool actually does, such as retrieving a snapshot of system settings, so it is essentially tautological.

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 guidance on when to use this tool versus alternatives. In particular, it does not distinguish itself from similarly named siblings like system_get_context_snapshot or system_get_appearance_settings, leaving the agent without routing information.

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