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 states what elements are summarized but does not disclose side effects, required permissions, or whether the operation is read-only. The lack of behavioral context beyond the extraction list is a significant gap.

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 wasted words. It is front-loaded with the verb and resource. However, it could be slightly restructured for clarity without losing conciseness.

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 6 undocumented parameters and no output schema, the description should explain expected output format and parameter usage. It only lists extracted elements, leaving the agent without enough context to call the tool correctly.

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 6 parameters with 0% description coverage in the schema, and the tool description does not mention any parameter. The agent receives no guidance on what tabId, debugUrl, maxElements, etc., control. This is a critical deficiency.

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 'summarize' and the resource 'selected page' with specific elements (text, links, buttons, etc.). It distinguishes from siblings like chrome_screenshot or chrome_click, though it doesn't explicitly contrast them. Overall, purpose is clear and specific.

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 phrase 'for automation planning' implies when to use the tool, but there is no explicit guidance on when not to use it or mention of alternative tools. Usage context is implied but not fully developed.

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