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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds one useful behavioral fact — that the returned flow names map onto other tools — but says nothing about scope limits, freshness of the data, or whether the facts are firm-specific only.

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?

Everything is packed into one long sentence with stacked parentheticals, and the key directive 'Call this first' is buried at the end rather than front-loaded. The content is relevant but the structure makes the reading order backwards for an agent deciding what to call.

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 no parameters and no output schema, the description carries the burden of describing the return payload, and it does so item by item (services, virtual office, nominee director, policy links, process). Only minor gaps remain, such as whether the response is a single firm or a list of firms matching a jurisdiction.

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 no parameters (0 required, empty schema), so there is nothing for the description to disambiguate. Baseline 4 applies; no parameter meaning is missing.

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 names the resource (company secretarial firm) and enumerates the concrete payload: available services with their flow names, virtual office address and nominee director flags, policy links, and process explanation. That is specific enough to distinguish it from siblings like describe_flow or list_packages, though it never states a clean verb such as 'retrieve the firm's profile'.

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?

'Call this first' gives an explicit ordering instruction relative to the other tools, and the parenthetical about flow names tells the agent this feeds into flow-based siblings. It stops short of naming which sibling to call next or any condition under which it should be skipped.

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