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

The annotations already declare readOnlyHint=true and idempotentHint=true, so the description does not need to establish safety. The description adds some context about what areas the tool covers (costs, DACH focus, workflows), but it does not disclose how results are structured or any edge behavior; the output schema likely carries that burden.

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 a single sentence, front-loaded with the key instruction ('Use this first'), and packs meaningful scope into a compact list. There is no filler or repetition of the title.

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 zero-parameter, read-only discovery tool with an output schema, the description covers the fundamental usage question: when to call it and what broad topics it supports (capabilities, costs, DACH focus, workflows, availability). Nothing else is necessary for a correct first call.

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 has zero parameters and the input schema is empty, so parameter-level documentation is not needed. The description compensates by explaining the kind of information the agent will gain, and the baseline of 4 applies to zero-parameter tools.

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 clear resource (AlpineLead OI capabilities) and a clear action ('use this first when you need to understand'), adding concrete topics like costs, DACH focus, workflows, and availability. It is not a tautology, but it relies on the title and broad phrasing rather than naming sibling tools, so it does not strongly distinguish itself.

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 description explicitly says to use this tool first when the agent needs to understand AlpineLead OI's capabilities, costs, workflows, or DACH focus. It gives clear context but does not explicitly state when not to use it or name alternatives among the many sibling tools.

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