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

With no annotations, the description must carry the behavioral burden. It does add useful behavior: for each URL, Glubler checks gDatabase or scrapes/fetches missing metadata and favicons automatically. But it omits important side-effect details such as whether duplicates are handled, whether login is required, what happens on invalid URLs, or what the response contains.

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 two tightly written sentences with the primary purpose front-loaded. Every word earns its place: the first sentence states scope, and the second explains the automatic metadata/favicon behavior. No filler or redundancy exists.

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 mutating batch operation with no annotations and no output schema, the description is sufficient for a basic call but incomplete for confident use. It explains the action and processing behavior, but does not disclose return values, failure modes, authentication expectations, or impact on an existing Glubler's contents.

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 already documents both parameters with 100% coverage, so the description does not need to restate them. The 'for each URL' phrasing reinforces how the urls array is processed, but it adds no new format or constraint details beyond what the schema provides.

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 uses a specific verb, 'Glue/save', names the resource 'Glubler', and emphasizes 'multiple websites at once', which clearly marks this as the batch counterpart to the singular glue_website sibling. This makes the tool's purpose unambiguous and distinguishable.

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 phrase 'multiple websites at once' clearly communicates the batch-use context, and an agent can infer that single-website cases should use glue_website instead. However, the description does not explicitly name that alternative or state when not to use this tool, so it misses full routing clarity.

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