take_snapshot

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

No annotations are provided, so the description carries the burden for behavioral disclosure. It mentions the source (DOM/a11y tree) and output (elements with UIDs), and indicates the result can be attached or saved via filePath. But it lacks details on output format, caching behavior, performance implications, or failure conditions.

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 three sentences with no redundancy. It front-loads the primary action and attaches key details about output and usage preference. It could be slightly more structured but is efficient.

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 absence of an output schema and annotations, the description provides adequate but incomplete context. It explains the tool's purpose and output but does not detail return format, how to use UIDs, or differentiate from other content tools like 'get_page_content'. It only contrasts with 'take_screenshot'.

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 coverage is 100%, so the baseline is 3. The description does not add meaningful information beyond what the schema already provides for both 'verbose' and 'filePath' parameters.

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 it takes a text snapshot of the current page based on the DOM/a11y tree, listing elements with UIDs. It distinguishes itself from the sibling 'take_screenshot' by explicitly preferring a snapshot over a screenshot.

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?

It advises to always use the latest snapshot and prefers snapshots over screenshots, providing clear context for use. However, it does not mention when not to use the tool or compare with other content retrieval tools like 'get_page_content' or 'get_html_source'.

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