watchlist_delete

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

No annotations are provided, so the description carries the full burden. 'Delete' implies a destructive action, but the description does not disclose whether deletion is permanent, irreversible, or whether it cascades to watchlist items. It also does not mention any safety or idempotency behavior. This leaves the agent unaware of important side effects.

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 brief sentence, which is concise, but it is under-specified. It lacks essential details about the operation, making it minimally adequate but with clear gaps. It earns its place but could be expanded to provide more value without becoming verbose.

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?

While an output schema exists (so return values are covered), the description lacks contextual information. For a destructive tool with no annotations, it should mention permanence, prerequisites, or how to identify the target watchlist. The presence of sibling tools adds potential confusion without explicit disambiguation. This is incomplete for a safe invocation.

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% and the description provides no information about the parameters (agent, account, watchlist, idempotency_key). The names are somewhat self-explanatory, but required parameters like 'account' and 'watchlist' are not clarified, and optional parameters like 'agent' and 'idempotency_key' are completely unexplained. This fails to compensate for the lack of schema descriptions.

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 'Delete a persistent watchlist' clearly states the action (delete) and resource (persistent watchlist). It does not explicitly differentiate from sibling watchlist_remove, but the verb 'delete' versus 'remove' and the name 'watchlist_delete' imply deleting an entire watchlist rather than a symbol. This is a clear purpose but lacks explicit sibling distinction.

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 provided on when to use this tool versus alternatives like watchlist_remove. There is no mention of prerequisites (e.g., needing an existing watchlist) or context for when deletion is appropriate. This is a clear gap in usage guidance.

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