Delete Price Alert

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

Annotations already signal destructive and idempotent behavior; the description adds that a successful call returns the upstream API response and that an invalid alert_id produces an error. It does not contradict the annotations and adds useful call outcome context, though it does not elaborate on permanence or 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?

Two sentences, each earning its place: the first states the action and required identifier, the second summarizes success/error outcomes. No filler.

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 one-required-parameter delete operation, the description covers what is deleted, where to get the ID, and the success/error contract. Since there is no output schema, 'Returns upstream API response' is enough to set expectations, though a slightly more concrete response shape would be more complete.

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 already documents both parameters, so the baseline is 3. The description adds the crucial fact that alert_id is a 'numeric string from alert_list', which is more specific than the schema's 'Alert indicator id' and explains the expected format/source.

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?

Description opens with the action verb 'Delete' and names the exact resource ('price alert') plus the required identifier source ('alert_id ... from alert_list'). This clearly distinguishes it from sibling alert tools such as alert_disable and alert_enable.

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 states that the alert_id must come from alert_list, giving the agent the prerequisite lookup step. It implies deletion as opposed to disable/enable but does not explicitly say when to prefer delete over alert_disable, so it lacks formal exclusions.

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