Behavior2/5

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

The description indicates the tool removes symbols, implying a destructive action, but with no annotations, it fails to disclose other behavioral traits like reversibility, authentication needs, or side effects. The description is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is very short and includes a structured Args list. It is concise and efficient, though slightly under-specified.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite the presence of an output schema, the description does not mention return values or confirmation. For a mutation tool, this leaves the agent uncertain about the outcome. No annotations compensate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, but the description adds basic semantics: watchlist_name is the name and symbols is a list. This provides minimal additional meaning beyond the schema's type definitions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (Removes symbols) and the resource (watchlist). It provides a clear purpose, though it does not differentiate from sibling tools like 'add_to_watchlist' or 'unified_remove_from_watchlist'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is given on when to use this tool versus alternatives such as 'unified_remove_from_watchlist' or for batch operations. No exclusions or prerequisites are mentioned.

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