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

With no annotations, the description carries the burden of behavioral disclosure. It explicitly states that the price watch is deleted 'and its recorded history', which is a meaningful side effect beyond a simple delete. This adequately communicates the destructive nature and cascading effect.

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 that conveys the entire operation without any filler or redundancy. Every word earns its place, and it is front-loaded with the verb and object.

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 low-complexity tool with one parameter and no output schema, the description is fairly complete. It states the action and the critical side effect (history deletion). It lacks details about return values or error cases, but these are less critical for a simple delete operation.

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 schema has 0% coverage and only one parameter, watch_id. The description says 'by id', which matches the schema title 'Watch Id', but does not add significant extra meaning beyond the schema. It is adequate but minimal, not fully compensating for the low schema coverage.

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 uses a specific verb 'Delete' with a clear resource 'price watch' and adds the detail '(and its recorded history)'. This clearly distinguishes it from siblings like track_price, list_price_watches, and get_price_history. The operation is unambiguous.

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 implies the use case (when you no longer want to track a price), but it does not explicitly state when to use it versus alternatives or provide exclusions. The sibling tools provide context, but the description itself lacks explicit guidance.

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