create_sync_watchlist_remove

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

Annotations already declare idempotentHint=true and destructiveHint=false; the description adds the endpoint and the advice to consult GET/schema, but no additional behavioral details (e.g., whether removal is permanent, any side effects, or authentication requirements). It does not contradict the annotations, but it does not enrich them.

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 brief: one line for purpose, one for the endpoint, and a short argument note. It is not padded with filler, though the 'Args: body: Request payload.' line is somewhat redundant with the schema. Overall, it is efficiently sized.

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 write operation with an open body schema and an output schema, the description is underspecified. It does not explain what the response will contain, what errors might occur, or how to construct the request beyond pointing to external docs. Given the complexity of the sync resource and the presence of siblings, the description leaves too much to discovery.

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 a single 'body' object with additionalProperties:true, offering zero field definitions (0% schema coverage). The description compensates partially by directing the agent to 'the matching GET or the /schema endpoint first,' but it does not actually describe what fields the body expects (e.g., item IDs to remove). This is a significant gap for a tool that requires a structured payload.

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 clearly states the verb and resource: 'Remove items from watchlist.' It also provides the HTTP endpoint, making the operation unambiguous. However, it does not explicitly distinguish itself from similarly-named siblings like create_sync_watchlist (which adds) or create_sync_watchlist_reorder, though the verb 'remove' differentiates reasonably.

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 on when to use this tool versus alternatives. It does not mention that this is for removing specific items (as opposed to clearing the watchlist) or how it relates to other sync operations like create_sync_collection_remove. The only instruction, 'Read the matching GET or the /schema endpoint first,' is about field discovery, not usage context.

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