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; the description usefully confirms this by stating it 'opens nothing by itself' and describing the return payload as screens/buttons/fields, which is real added value since no output schema exists. However, the trailing sentence about Lexware Office having 'a public REST API with an API key (checked 14 Oct 2026)' muddies whether this tool calls that API, and the date is in the future, undermining trust in the claim.

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 and the follow-up workflow is clear, but the text is padded: 'Lexware Office (lexoffice)' is repeated four times in three sentences, and the closing API-existence sentence earns no place in a tool that takes no parameters and performs no API call. Roughly a third of the description is redundant branding plus an irrelevant aside.

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 zero parameters and no output schema, the description carries the burden of explaining what comes back, and it does: a step-by-step guide with screens, buttons and fields. It also explains the hand-off to browser tools so the agent knows the job is not done here. Missing only edge conditions such as what happens if the user is not signed in or the browser session is unavailable.

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 tool takes zero parameters, so there is nothing for the description to disambiguate; baseline 4 applies. The description implicitly fits this—the agent supplies no inputs and receives instructions back.

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 opening sentence says the tool will 'Create quote in the user's own Lexware Office account', a clear verb+resource, but the next sentence reverses that framing: it 'Returns how to do it ... step by step ... and opens nothing by itself.' The agent must reconcile these two statements to learn the tool only produces guidance, not a quote. It also never distinguishes itself from the sibling lexware_office_create_invoice or cotlet_app_guide, so sibling routing remains ambiguous.

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?

It gives explicit sequencing: get the step-by-step guide here, then execute 'with the cotlet_browser_* tools in the user's Lexware Office Cloud Browser.' That names the concrete alternative and the condition for using it. It stops short of saying when not to use this tool (e.g. when the official API or create_invoice is preferable), which keeps it from a 5.

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