remove_from_watchlist

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

No annotations are provided, so the description carries full burden. It states the action is a removal, implying a destructive mutation, but doesn't disclose behavioral traits such as permissions needed, whether the operation is reversible, error handling (e.g., if symbol isn't in watchlist), or rate limits. This leaves significant gaps for an agent to understand the tool's behavior.

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, clear sentence with zero waste—it directly states the tool's action and target. It's appropriately sized for a simple tool and front-loaded with the essential information, making it highly concise and well-structured.

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 low complexity (1 parameter, no annotations, but has an output schema), the description is minimally complete. It states what the tool does, but lacks details on usage, parameters, and behavioral context. The output schema may cover return values, but the description doesn't provide enough guidance for effective use, making it adequate but with clear gaps.

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 input schema has 1 parameter with 0% description coverage, and the tool description doesn't add any semantic details about the 'symbol' parameter. It doesn't explain what format the symbol should be in (e.g., ticker symbol like 'AAPL'), examples, or constraints. With low schema coverage, the description fails to compensate, leaving the parameter poorly documented.

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 states the action ('removes') and resource ('a symbol from the watchlist'), which is clear but basic. It doesn't differentiate from sibling tools like 'add_to_watchlist' beyond the verb, and lacks specificity about what type of watchlist or symbols are involved (e.g., stocks, crypto). This makes it vague in context.

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 is provided on when to use this tool versus alternatives. It doesn't mention prerequisites (e.g., the symbol must already be in the watchlist), exclusions, or related tools like 'add_to_watchlist' for managing the watchlist. The description is standalone with no contextual usage hints.

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