rename_mylist

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

Annotations already provide readOnlyHint=false, destructiveHint=false, and idempotentHint=true. The description adds that user approval is required, which is a key behavioral constraint, and that the change must be exactly as approved. This complements the schema's confirm field and goes beyond the annotations.

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 sentence, front-loaded with the action 'Rename a DigiKey MyList' and includes the critical approval condition. Every word adds value, with no redundancy or filler.

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 rename operation, the description plus annotations provide sufficient context: purpose, approval requirement, non-destructive, idempotent, and mutation. No output schema exists, so return values are not expected. It could mention prerequisites like list existence or failure modes, but these are not essential for basic use.

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 description coverage is 0% for the two parameters. The description does not explicitly detail parameters, but the phrase 'the exact change' implies new_name must match user approval, and 'after the user approves' maps to the confirm boolean. However, account_id and other nested properties remain unexplained, so the description only partially compensates for the lack of schema descriptions.

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 'Rename' with the resource 'DigiKey MyList', clearly indicating the operation. It is distinct from sibling tools like create_mylist or delete_mylist, though it does not explicitly name alternatives. The approval qualifier adds precision and helps differentiate it from a simple rename without confirmation.

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 states the intended use case: renaming a list after the user approves the exact change. This implies that user confirmation is a prerequisite and that this tool should be invoked only after approval. It does not mention exclusions or alternatives, but the context is clear enough for selection.

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