analytics_content_performance

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

No annotations are provided, so the description carries the full burden. It implies a read-only operation ('Analyze...in GA4') but does not explicitly state safety, auth requirements, or other behavioral traits. While typical for analytics tools, more clarity on side effects would improve 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 concise sentence (20 words) with no redundancy. It front-loads the action and prerequisite efficiently, though it could include more detail without being overly verbose.

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?

With no output schema, the description should hint at what the analysis returns (e.g., metrics, dimensions). It only says 'analyze content performance', which is vague. The prerequisite is helpful, but lacking output context makes the tool incomplete for an agent.

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 input schema has 100% description coverage, so the schema already documents each parameter's meaning. The description does not add any additional context or relationships beyond the schema, thus providing no extra value.

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 verb 'analyze' and the resource 'content performance by Content Group in GA4', making the purpose understandable. However, it does not differentiate from similar siblings like 'analytics_page_performance' or 'analytics_organic_landing_pages', which also analyze content.

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 provides a key prerequisite: 'Requires Content Groups to be configured in GA4 Admin', which tells when to use it. However, it does not mention when not to use it or suggest alternative tools among the many analytics siblings.

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