navigate_and_read

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

With no annotations, the description provides basic behavioral traits: navigate, extract text, close tab. It implies a read operation but does not disclose potential side effects, error behavior, or waiting logic (despite wait_ms parameter). Adequate but not detailed.

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?

Single sentence, front-loaded with key information. No wasted words, but omits important parameter details. Overall efficient for the core action.

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 has 4 parameters, no output schema, and no annotations, the description is too brief. It does not explain return values, optional parameters behavior, or constraints (e.g., host/port are for browser debugging, wait_ms controls load time). Incomplete for effective 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 0%, yet the description adds no meaning to any of the four parameters. Only 'url' is implicitly referenced; host, port, and wait_ms are completely unexplained. The description fails to compensate for missing schema descriptions.

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 navigates to a URL, extracts visible page text, and closes the tab. It identifies itself as an alias for extract_content, which gives specific verb and resource context. However, calling it an alias does not differentiate it from its sibling tool extract_content, slightly reducing clarity.

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 provided on when to use this tool versus alternatives. It merely states it is an alias for extract_content, implying they are interchangeable, but does not offer contextual hints or exclusions.

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