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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered elsewhere. The description adds that it is a listing with folder/kind filtering, which is useful context, but says nothing about pagination behavior despite limit/offset parameters. With annotations doing the heavy lifting, a 3 is appropriate.

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 purpose is front-loaded, which is good, but the entire description is duplicated in Norwegian and English, effectively doubling its length for the same content. The long kind list is also repeated verbatim from the schema enum. Functional but not 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?

For a filtered-list tool with an existing output schema, the description covers purpose, returned fields, and filter options, and annotations cover safety. The notable gap is pagination: limit/offset are neither explained in the description nor in the schema, which an agent listing potentially hundreds of pages would need. Otherwise complete enough.

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 50%: kind and prefix are documented in the schema, while limit and offset are not. The description compensates partly by giving concrete folder-prefix examples ('kommunale-avgifter', 'valuta', 'bolig') and enumerating the kind values, but it never explains the limit/offset pagination semantics. Marginal added value over 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?

The description states a specific verb and resource ('List the pages of pristavla.no') and enumerates the returned fields (title, URL, kind, date, headline number), so the agent knows exactly what the tool produces. It does not explicitly name or contrast itself with siblings like get_page or search, but the list-vs-get distinction is largely self-evident. Clear purpose, no explicit sibling differentiation.

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?

Usage is implied by 'optionally filtered by folder prefix or kind,' which tells the agent filtering is available. However there is no explicit when-to-use or when-not-to-use guidance and no reference to alternatives such as search or get_page for single pages. Adequate but leaves routing to inference.

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