remove_from_watchlist

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

With no annotations, the description carries the disclosure burden. It discloses the authentication requirement ('Requires API key') and implies a mutating action via 'Remove', but it does not describe potential side effects, irreversibility, or response/error 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, direct sentence followed by a necessary authentication note. It is front-loaded with the action and contains no extraneous words.

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 single-parameter mutation tool with no output schema, the description provides the core purpose and an important prerequisite (API key). It lacks details about edge cases (e.g., symbol not found, idempotency), but the low complexity makes this acceptable.

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% because the 'symbol' parameter already includes a description 'Ticker symbol to remove'. The tool description repeats the term 'ticker symbol' without adding new semantic details, so it adds minimal value beyond the schema.

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 ('Remove') with a clear resource ('ticker symbol from the watchlist'), making the tool's purpose unambiguous and distinguishing it from sibling tools like add_to_watchlist and list_watchlist.

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 only mentions the prerequisite of an API key and gives no explicit guidance on when to use this tool versus alternatives. It does not state any exclusions or mention that list_watchlist could be used to view current symbols before removal.

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