create_actions_remove_from_watchlist

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

The annotations already signal an idempotent, non-destructive mutation. The description adds the HTTP method and endpoint, but the 'add or remove' phrase conflicts with the remove-only operation and no additional behavior (such as missing-item handling or auth needs) is disclosed.

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 appropriately short and front-loaded with the operation. There is no filler, though the misleading 'add or remove' phrase is a substantive error even if it does not make the description overly long.

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?

The tool itself is simple and the output schema plus annotations cover return values and safety. However, the conflicting parameter wording and lack of guidance for selecting this tool over its add-to-watchlist sibling leave the description incomplete for reliable agent 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?

With 0% schema description coverage, the description carries the full burden of explaining uri. It identifies uri as the item URI, but says 'add or remove' for a removal endpoint and fails to explain optionality, expected URI format, or what null/default means.

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 opening line 'Remove from Watchlist' plus the endpoint POST /actions/removeFromWatchlist clearly states the action and resource. It is distinguishable from the sibling create_actions_add_to_watchlist by the word 'remove', though it does not explicitly reference that sibling. The parameter line's 'add or remove' wording slightly muddies the otherwise clear purpose.

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 given about when to use this tool versus create_actions_add_to_watchlist or other watchlist-related tools. The agent must infer usage entirely from the tool name and the one-line summary.

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