Create Sharelist

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

Annotations already indicate readOnlyHint=false, idempotentHint=false, and destructiveHint=false. The description adds minimal extra context beyond noting it's a 'community' sharelist. It doesn't disclose potential side effects, authentication requirements, or other behavioral nuances, but given the annotations cover the basic safety profile, the description's additional value is limited.

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 directly states the tool's function without redundancy. Every word earns its place, and it is appropriately front-loaded with the core action.

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 creation tool with an output schema present and full parameter coverage, the description is sufficient. It lacks detailed examples or edge cases, but given the simplicity and available structured metadata, it does not need more. The absence of any mention of the return value is fine because the output schema exists.

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 schema covers 100% of parameters with descriptions, so the baseline is 3. The description adds a brief mention of 'name and optional description,' which aligns with the schema. However, it does not mention the defaulting behavior for description, which is in the schema but not in the description. This is a minor gap, justifying a 4 rather than 5.

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 (create) and the resource (community sharelist), making the tool's purpose unambiguous. However, it does not explicitly differentiate from sibling tools like sharelist_add or sharelist_delete, although the name strongly implies creation. Slight deduction for missing explicit sibling distinction.

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 implies when to use this tool (when creating a new sharelist) but provides no explicit guidance on when not to use it or mention alternatives. Given the sibling set includes sharelist_delete, sharelist_add, etc., the usage context is obvious from the name but not articulated in the description.

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