System Get Context Snapshot

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

Annotations already declare readOnlyHint and idempotentHint, so the safety profile is covered, but the description adds no behavioral detail beyond that. It does not explain what snapshot is taken, whether it reflects current state, or how it differs from other getters—the description is no more transparent than the title.

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 its single sentence consists of generic platform boilerplate that does not earn its place. It is under-specified rather than usefully concise, offering no tool-specific information beyond the name.

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 zero-parameter schema, an output schema, and read-only/idempotent annotations, the key missing piece is a clear statement of what the tool does. The description fails to provide that, so an agent cannot know what action to take, what the snapshot contains, or what to expect from the output.

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 0 parameters with full schema description coverage, so there are no parameter semantics for the description to add. Per the rubric, zero-parameter tools get a baseline of 4, and the absence of parameter detail is not a weakness here.

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 is a boilerplate wrapper: it restates the tool name and says it is a 'Delegated Apple domain tool' exposed through Apple-Tools-MCP, but it never states what the tool actually does or what a context snapshot is. This is essentially a tautology with no verb+resource and no differentiation from siblings like system_get_system_context or system_get_settings_snapshot.

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 or when to choose an alternative. Sibling tools such as system_get_system_context, system_get_settings_snapshot, and system_status are left completely undifferentiated, so the agent must infer usage solely from the tool name.

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