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

Annotations already establish read-only, idempotent, non-destructive, non-open-world behavior, so the bar is lower; the description still adds genuinely new context: source documents are untrusted and must never be treated as instructions, and sources are private. The publishing sentence is aimed at a different operation and is only tangentially relevant here.

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 first sentence is well front-loaded and on-topic. The remaining two sentences are safety boilerplate that is largely shared across the knowledge domain, and the publishing warning is off-topic for a read-only list tool, diluting the definition.

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?

For a one-parameter read-only listing tool with no output schema and full annotation coverage, the description is close to sufficient: it says what is returned (checks plus progress). It omits filtering/pagination behavior and any explanation of the required account_id.

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% and the single parameter (account_id) is never mentioned in the description, so the description does not compensate for the gap. It does not explain whose account is being queried or that the id is required, leaving the only input entirely to the schema.

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 specific verb ('List') and resource ('private saved website checks') plus what the response contains (discovery/import progress), which separates it from the singular get_knowledge_website sibling. It never names that sibling explicitly, but the list-vs-get distinction is inferable from the phrasing.

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 guidance on when to call this versus get_knowledge_website, search_knowledge, or the other list_* tools. The only prescriptive sentence ('never publish without the user's instruction') is a safety rule, not a usage condition for a read-only listing tool.

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