subscription_settings_update_settings

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

With no annotations, the description carries the full behavioral burden and delivers nothing. It does not disclose that this is a mutation, whether unspecified fields are preserved or reset, whether elevated permissions are required, or that a confirm:true gate governs execution (that constraint lives only in the schema).

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?

Very short and front-loaded with the action, so there is no bloat to penalize. However, one of its three lines is auto-generated 'Tags:' boilerplate that adds no selection value, leaving the description minimal rather than efficiently informative.

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 high-complexity mutation tool with a deeply nested body (HWID settings, custom remarks, response rules), no annotations, and no output schema, the description is completely inadequate. It omits scope of the update, authorization needs, the confirm gate, and any indication of what the PATCH affects globally.

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?

Two top-level parameters with ~50% description coverage, and the description adds zero parameter meaning. The nested body schema is unusually self-documenting (extensive markdownDescription on hwidSettings, customRemarks, responseRules, and confirm), so the schema does the work, but the description contributes nothing to compensate for the coverage gap.

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 essentially a tautology of the tool name: 'Update subscription settings' against subscription_settings_update_settings. The only added signal is the HTTP verb/path (PATCH /api/subscription-settings), which hints at partial-update semantics but does not state what is actually being changed or distinguish this from sibling mutators like remnawave_settings_update_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?

No when-to-use, when-not-to-use, prerequisites, or named alternatives are provided. An agent is given no basis for choosing this over remnawave_settings_update_settings or subscription_settings_get_settings.

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