st.mvu.settings.get

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It clearly indicates this is a read-only operation and that it reports the exact extension_settings storage path, which is useful behavioral context. It does not detail the exact shape of returned settings, but for a zero-parameter getter this is adequate.

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?

The description is a single concise sentence that front-loads the operation and resource, then states the distinctive output. Every word contributes value, and there is no filler or repetition of the tool name beyond the necessary MVU reference.

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 simple zero-parameter read tool with no output schema, the description covers the essential context: what is read, and what is reported. A slightly fuller statement of return shape or usage context would make it completely self-contained, but nothing critical is missing for an agent deciding whether to invoke it.

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 has zero parameters and the schema has 100% description coverage by virtue of being empty, so there are no parameter semantics to document. The description appropriately adds no redundant parameter information, matching the baseline for a no-parameter tool.

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 uses a specific verb, 'Read', names the exact resource, 'MagVarUpdate/MVU global settings', and adds a distinctive output detail, 'report their exact extension_settings storage path'. This clearly sets it apart from generic config readers like st.config.get and from mutators like st.mvu.settings.configure.

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 guidance on when to choose this tool over alternatives such as st.config.get, st.config_locations, or st.mvu.settings.configure. The read-only purpose is implied by the wording, but no explicit context or exclusions are provided.

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