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

No annotations are provided, so description must carry behavioral disclosure. It indicates a write operation and a necessary environment condition. However, it lacks details about idempotency, overwrite behavior, failure modes, or effect on existing data.

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?

Description is one short sentence (15 words) that is front-loaded and efficient. Every word adds value, no redundancy.

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 5 parameters, no annotations, and an output schema that may cover return values but is not referenced, the description is incomplete. It fails to explain parameters, error cases, or usage context beyond the environment requirement.

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%, and the description does not explain any of the 5 parameters (slug, property_id, stream_name, website_url, measurement_id). The agent has no guidance on what each parameter means or how to fill them.

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 clearly states the tool writes GA4 metadata to a specific destination (launcher registry project.analytics.ga4), using precise verb and resource. It distinguishes from sibling tools that deal with different aspects of GA4 integration.

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 mentions a prerequisite ('requires writable env'), providing clear context for usage. However, it does not explicitly state when not to use this tool or compare to alternatives, missing a complete guideline.

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