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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so safety is partly covered. The description adds genuine value beyond that: page contents remain private, sources are private, and source documents/page content are flagged as untrusted data that must never be treated as instructions. The closing note about 'Publishing changes public pages' is confusing boilerplate in a read-only tool, since this tool does not publish.

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?

Front-loaded with the read purpose and contents, and the untrusted-data warning earns its place. 'Page contents stay private' and 'Sources are private' are partly redundant, but the four sentences are otherwise compact and unambiguous.

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?

With no output schema, the description steps in to describe the returned contents (eligible pages, skipped reasons, limits). Annotations cover the safety profile, so the only real gap is the undocumented account_id/run_id semantics.

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% for two required params, so the description must carry the burden and largely does not. 'Saved website check' hints that run_id references a prior run, but account_id is never explained and neither UUID parameter gains format, scope, or scoping detail.

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?

States a clear verb and resource ('Read a saved website check') and enumerates what the read returns: 'discovered eligible pages, skipped reasons and limits.' This distinguishes it from list_knowledge_websites, but it does not explicitly differentiate it from nearby siblings like get_knowledge_source or get_knowledge_page, leaving an agent to infer the boundary from the name alone.

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?

There is no explicit when-to-use/when-not-to-use guidance or named alternative. The required run_id implicitly signals that a prior run must exist and this reads its saved result, which is enough to infer usage, but routing to the correct sibling remains unstated.

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