Set a nested setting

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

The description adds meaningful behavioral detail beyond annotations: it creates intermediaries and snapshots the previous state for nuvio_undo. The annotations already indicate this is not read-only and not idempotent, but the description enriches the mutation model with reversible write behavior.

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?

Three sentences, with no filler. The core purpose and path examples are front-loaded, and the undo/rollback behavior is provided as a short follow-up. Every sentence contributes information an agent needs.

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 four-parameter setter with no output schema and annotations already covering read-only/idempotent/destructive traits, the description is sufficiently complete: it explains the path syntax, creation behavior, and undo path. It could mention `platform` and `profile_id` more explicitly, but the schema already supplies those details.

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 description adds value for the primary path parameter with dot-path examples and semantics for creating intermediate objects/arrays, going beyond the schema's brief 'Dot path into settings_json.' Platform and profile_id remain schema-managed with defaults and explanations, and overall schema coverage is 75%, so the description does not need to duplicate every parameter.

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 states a specific verb and resource: 'Set one nested value by dot path,' with concrete examples. This clearly distinguishes the tool from sibling tools like nuvio_update_settings, which implies a broader settings update, and nuvio_unset_setting.

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 description gives enough usage context by explaining dot-path semantics and noting that intermediate objects/arrays are created. However, it does not explicitly contrast this tool with nuvio_update_settings or nuvio_unset_setting, leaving when-not-to-use guidance implied rather than explicit.

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