remove_from_watchlist

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

No annotations are provided, so the description carries the full burden. It states the removal operation is 'local,' which hints at side effects, but doesn't disclose whether removal is destructive/permanent, requires auth, or whether removing a nonexistent item errors gracefully. No mention of what happens to the item or any related state.

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 concise sentence with zero waste. It's appropriately brief for its simplicity, though it could be expanded with useful guidance.

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 mutation tool (removal) with no annotations, no schema documentation, and an ambiguous item_id parameter, the description is underspecified. An output schema exists which helps, but the ambiguity around what item_id identifies and lack of behavioral disclosure leaves meaningful gaps for a tool that could destroy data.

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 description coverage is 0%, so the description must compensate. The single parameter item_id is an integer, but the description doesn't clarify what an 'item_id' refers to (watchlist entry ID vs card ID), how to obtain it, or whether it's the same ID used elsewhere (e.g., list_watchlist). This ambiguity could cause agent errors.

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 'Remove a local watchlist item' - a clear verb+resource. However, it doesn't differentiate from siblings like remove_collection_item. 'Local' hints at local vs remote but this isn't elaborated.

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 when-to-use guidance is provided. 'Remove a local watchlist item' doesn't explain when to use this vs remove_collection_item or update_collection_item. No mention of check_watchlist or list_watchlist to verify before removal.

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