analyze_pagespeed_batch

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

With no annotations provided, the description must disclose all behavioral traits. It mentions concurrency limits and API version, but fails to mention authentication requirements, rate limits, error handling, or any side effects. The return format is only vaguely described as 'compact comparison'.

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 in Portuguese, which is concise but lacks structure. It front-loads the key purpose but omits important details. It could be more informative without becoming 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?

Given the tool's complexity (batch API calls, concurrency, multiple parameters, no output schema), the description is insufficient. It does not explain the return format, result handling, or how it differs from related tools. An agent would lack critical context for correct usage.

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 50% (urls and concurrency have descriptions), but the description adds no extra meaning beyond the schema. The strategy and categories parameters, which lack schema descriptions, are not elaborated in the description. Thus the description does not compensate for the coverage gap.

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 tool analyzes up to 10 URLs using the PageSpeed Insights API v5 with concurrency limits and returns a compact comparison. It effectively distinguishes from siblings like analyze_pagespeed (likely single URL) and compare_web_performance by specifying the batch capability.

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 this tool versus the sibling tools. The description does not explicitly state that it is for batch analysis or that analyze_pagespeed is for single URL. An agent would have to infer from the name, which is unreliable.

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