Snapshot Page

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

No annotations are provided, and the description does not disclose behavioral traits such as side effects, idempotency, authorization requirements, or rate limits. The tool saves a snapshot, but it's unclear if this is a destructive or state-changing operation.

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, but it is overly concise, lacking crucial details about parameters and behavior. It achieves conciseness at the cost of completeness.

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?

While an output schema exists (reducing need for return value description), the description fails to explain what constitutes a 'structured snapshot' or how it differs from a simple page read. The tool's role in the snapshot-diff workflow is implied but not fully elaborated.

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 schema has 2 parameters (url, label) with 0% description coverage. The description does not mention either parameter or their usage, leaving the agent without any guidance on how to populate them.

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 'Save a structured snapshot' and the resource 'Ninova page', and mentions the purpose 'for later comparison'. It implicitly distinguishes from siblings like read_page (no snapshot) and diff_snapshot (comparison only). However, 'structured snapshot' is somewhat vague.

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 does not provide explicit guidance on when to use this tool versus alternatives. It only hints at use for later comparison, but no exclusions or when-not-to-use scenarios are mentioned.

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