Rename watchlist

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

The annotation 'idempotentHint: true' is provided, indicating safe repetition. The description does not contradict this, but adds no additional behavioral context (e.g., side effects, error conditions).

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?

Single, clear sentence with no filler. Perfectly concise.

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 with full schema and annotation, the description is minimally adequate. However, it lacks details about return values or error handling (e.g., behavior if watchlist not found).

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 100%, and parameters are described in the schema (e.g., maxLength, minLength). The description does not add extra meaning beyond what the schema already provides.

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?

Description clearly states 'Rename an existing watchlist', indicating a specific verb and resource. It distinguishes from sibling tools like create_watchlist or delete_watchlist, but could be more detailed about the action's effect.

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?

No guidance on when to use this tool versus alternatives (e.g., when to rename vs. create or delete). The description only states what it does, not the context or prerequisites.

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