Get settings

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is fully covered without the description. The description adds no behavioral context beyond the field listing — no return format, no mention of defaults for unset values, no units. With annotations carrying the load, this is thin but not contradictory.

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 fragment with no filler, and the three setting categories are enumerated compactly. It is efficient, though the fragmentary phrasing means there is no lead sentence establishing the action.

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 no output schema, the description is the only source of what comes back, and it does name three categories of returned data. However, 'timer settings' is left vague and there is no indication of format, units, or whether all settings or only user-modified ones are returned, leaving the agent guessing about the response shape.

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 takes zero parameters, so per the rubric the baseline is 4. There is no parameter surface for the description to explain, and the empty schema is consistent with a no-argument getter.

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 name and title ('Get settings') carry the verb, but the description itself is a bare noun phrase listing setting categories rather than stating that it retrieves current values. It does add field-level detail (timezone, reminder destination, timer settings) that tells an agent what 'settings' means here, but it never differentiates itself from the sibling set_settings.

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 guidance at all — no mention that this is the read counterpart to set_settings, no indication of when an agent should fetch settings versus using get_planning_context or get_now. The agent must infer usage purely 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.
