serpwatcher_create_annotation

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

With no annotations provided, the description carries the full burden of behavioral disclosure. 'Create' implies a mutating operation, but no details are given about side effects, idempotency, required permissions, rate limits, or what happens on success/failure. The description is essentially a restatement of the tool name, offering no behavioral context.

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 sentence with no redundancy or fluff, making it concise and front-loaded. However, it is so brief that it borders on under-specification, but for conciseness alone it earns a solid score.

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?

Given the tool has 3 parameters, one required, and no output schema or annotations, the description is grossly insufficient. It does not mention required parameters, what the annotation contains, how it relates to tracking IDs, or what response to expect. An agent would not be able to confidently invoke this tool based on the description alone.

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 100%, with all three parameters (body, query, tracking_id) described in the schema. The description adds no additional parameter semantics beyond the schema, which is the baseline for high 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 'Create a SERPWatcher annotation' uses a specific verb ('Create') and clearly identifies the resource (annotation) within the SERPWatcher tool. It distinguishes from sibling tools like update/delete annotations through the verb, though it lacks detail on what an annotation is or how it relates to trackings.

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 (e.g., update_annotation, create_tracking). There are no exclusions, prerequisites, or contextual hints, so the agent gets no help in deciding when to invoke this tool.

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