update_system_settings

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

No annotations are provided, so the description carries the full burden. It discloses that the update is partial, which is genuinely useful, but says nothing about required permissions, whether changes are reversible, validation of keys, or side effects for a mutation tool.

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 key behavior ('partial update') stated first. The Args block is somewhat boilerplate but mirrors the parameters cleanly without waste.

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?

An output schema exists so return values need no explanation, and the tool is not deeply complex. But for a zero-annotation mutation with 0% schema coverage and an open-ended kwargs parameter, the description omits the acceptable setting keys and any permission/side-effect context an agent would need.

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?

Schema description coverage is 0%, and the description partially compensates by documenting settings_id ('usually 1') and describing kwargs as key-value pairs to update. However, it never enumerates which settings keys are valid or what types they take, leaving the free-form kwargs effectively undocumented.

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?

States a specific verb and resource ('Update system settings') and adds the useful qualifier 'partial update', so the agent knows existing values are preserved. It doesn't explicitly differentiate from the sibling get_system_settings, but the read/write verb split makes the distinction clear enough.

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 or when-not-to-use guidance and no mention of the get_system_settings counterpart or any preconditions. The '(partial update)' note hints at behavior but not at when this tool should be chosen.

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