get_output_settings

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

The description reveals that it reads from environment variable or a file, which is helpful. However, it does not mention failure modes (e.g., missing file), whether it is read-only, or any other side effects. With no annotations, a bit more detail would improve transparency.

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 exceptionally concise with two short sentences, no filler, and front-loaded with the core purpose. Every word earns its place.

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?

Given the simplicity (no params, no output schema), the description covers the basic functionality. However, it does not specify the format or structure of the returned settings, which might be needed for agents to use the output effectively.

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?

There are no parameters, so schema coverage is 100% by default. The description adds meaning by specifying data sources (NOUGAT_MCP_SETTINGS or ./settings.json), which is useful beyond the empty schema.

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 clearly states the action ('Return') and the resource ('resolved output settings'), with a clear purpose for agents to adapt behavior. While the sibling tool is unrelated, the purpose is specific enough to differentiate.

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 explicit guidance on when to use this tool or when to avoid it. The description lacks context about prerequisites or alternatives, such as if settings might be unavailable or how often to call it.

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