set_system_option

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

With no annotations, the description must fully disclose behavior. It lacks details on side effects, prerequisites, permissions, error handling, or persistence of changes. For a mutation tool affecting system state, this is insufficient.

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 short and front-loaded, with a clear purpose statement followed by structured parameter and return notes. Every sentence serves a purpose, though it could be more detailed without losing conciseness.

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 tool's complexity (modifying system options) and lack of annotations, the description fails to provide complete context. It omits when this tool is appropriate, what dedicated tools exist, and any behavioral expectations beyond a vague 'Confirmation' return.

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 coverage is 0%, so the description provides the only semantics. It offers example values for both parameters (e.g., option names and values), adding some meaning beyond bare schema. However, it does not explain constraints or valid ranges per option.

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 ('Set a specific SYStem.Option value') and identifies itself as a generic fallback for options not covered by dedicated tools. This provides good clarity on what the tool does and its scope.

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 mentions it's for settings not covered by dedicated tools, giving a general usage criterion. However, it does not list which dedicated tools exist or explicitly state when to prefer them, leaving gaps in decision guidance.

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