create_pixel_config

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

No annotations are present, placing the burden on the description to disclose behavioral traits. It only states the creation action without mentioning side effects, idempotency, domain ownership checks, or auth requirements, providing minimal transparency.

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, clear sentence that front-loads the core purpose. Every word is necessary, and no redundancy exists.

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 the description covers the basic function and schema covers all parameters, it omits information about return values or post-creation behavior, which is notable since there is no output schema. It is minimally adequate.

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?

Input schema has 100% description coverage, so the schema already documents parameters. The description adds no additional context beyond the schema, meeting the baseline but not surpassing it.

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 clearly states the action ('Create'), the resource ('pixel tracking configuration'), and the context ('for a website domain'), effectively distinguishing it from sibling tools like 'create_domain_verification' or 'list_pixel_configs'.

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 explicit when-to-use or when-not-to-use guidance is provided. The description implies usage for setting up tracking on a domain, but lacks comparison with alternatives or prerequisites.

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