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

With no annotations, the description carries the full burden. It discloses the auth requirement (platform staff, account session), which is meaningful, but says nothing about error behavior, response format, or caching/rate limits. It adds some context beyond the name but not a rich behavioral profile.

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 front-loaded sentence: the auth gate comes first, then the content. The parenthetical is dense but earns its place by defining the flag, and there is no filler.

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 zero-parameter getter with no output schema, the description names the settings it returns, which is the main thing an agent needs. It stops short of describing the response shape, but given the tool's simplicity the description is largely sufficient.

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. The description's parenthetical expands the meaning of the managedLiveCalling flag (cross-country calling for SAGOT lines in live mode), which is useful domain context even with no parameters.

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 verb 'get' plus 'Platform switches' and the named settings (managedLiveCalling, payments/SAGOT numbers configuration) make it clear this retrieves deployment-wide platform settings. It does not explicitly contrast with platform_settings_update, but the get/update naming on the sibling pair makes the read intent inferable.

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 access condition 'Platform staff only (account session)' is a real gating constraint, which is useful. However, there is no explicit when-to-use or when-not guidance relative to alternatives such as platform_settings_update, platform_overview, or platform_health, leaving selection largely to inference.

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