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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile needs no restating. The description still adds value by enumerating the return contents (links plus first four steps) in the absence of an output schema, and it reinforces scope with "Creates nothing" — useful, though redundant with destructiveHint=false.

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?

Two sentences, purpose first, with no filler. The first sentence is a dense chained enumeration of return items, which is slightly awkward to parse but every element is informative and nothing is wasted.

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?

A simple read-only onboarding tool with rich annotations, zero required parameters and a fully documented optional enum — so the remaining gaps are small. Coverage of what the tool returns and when to reach for it is adequate; only the language behavior and any follow-through after returning links are left implicit.

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 100% and the single optional language enum is fully documented in the schema, so the baseline is 3. The description says nothing about the language parameter or the fact that product/account answers may fall back to German, so it adds no meaning beyond 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 and enumerates the returned resource set (account link, sign-in, documentation, no-account tools, first four steps), which is far more concrete than the name alone. It does not explicitly contrast itself with onboarding-adjacent siblings such as create_product_draft, but the onboarding framing is distinctive enough to disambiguate.

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?

Provides one positive trigger ("Use when someone wants to publish their own data sheets"), which is implied usage rather than an explicit decision rule. No when-not guidance and no named alternative, even though a user wanting to publish data sheets could plausibly be routed to create_product_draft instead.

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