watch.add

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

No annotations are provided, so the description carries the full behavioral burden. It only implies a mutation by saying 'add', but it does not disclose duplicate behavior, whether existing keywords are updated, prerequisites, side effects, or alert semantics beyond the brief max_price mention.

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 front-loaded sentence with no wasted words. It immediately communicates the operation, the object, and the key optional parameter, which is appropriate for a simple CRUD-style tool.

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?

The tool is simple and an output schema is present, but the description omits min_price and gives no duplicate or overwrite behavior. It is minimally adequate for an experienced agent but still leaves important interpretation gaps.

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 for missing parameter documentation. It clarifies keyword and gives some meaning to max_price, but min_price is never mentioned, leaving one of the three parameters semantically unexplained.

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 a clear verb and resource: add a price-monitoring keyword, with an optional max_price low-price alert line. It is easily distinguished from removal or listing tools by the 'add' verb, though it does not explicitly distinguish it from watch.start or watch.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?

No guidance is given on when to use watch.add versus the many sibling watch.* tools, and no alternatives or exclusions are named. The intended use is only implied by the verb 'add' and the phrase 'price monitoring keyword'.

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