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 mentions the tool captures 'all visible content' but doesn't disclose behavioral traits such as performance implications, whether it requires browser initialization, potential rate limits, or how it handles dynamic content. This is inadequate for a tool with no annotation coverage.

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, well-structured sentence that efficiently conveys the core functionality without waste. It is front-loaded with the main action and resource. However, it could be slightly more concise by avoiding redundancy like 'etc.' after listing content types.

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 (capturing full page snapshots), lack of annotations, and no output schema, the description is incomplete. It doesn't explain what the snapshot output looks like (e.g., format, structure), performance considerations, or dependencies on tools like 'init-browser'. This leaves significant gaps for an AI 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 0 parameters with 100% coverage, so no parameter documentation is needed. The description appropriately adds no parameter information, focusing on the tool's purpose instead. A baseline of 4 is applied since no parameters exist, and the description doesn't introduce unnecessary details.

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's purpose with a specific verb ('Get') and resource ('complete snapshot of the page'), and specifies what content is included ('all visible content including text, images, forms, etc.'). However, it doesn't explicitly differentiate from sibling tools like 'get-full-dom' or 'get-text-snapshot', which likely serve similar purposes, preventing a perfect score.

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 minimal guidance by stating the tool is for 'understanding the full context', which implies usage when comprehensive page analysis is needed. However, it lacks explicit when-to-use advice, alternatives (e.g., vs. 'get-text-snapshot' for text-only), or exclusions, leaving the agent with limited direction.

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