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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds that the payload is informational (product, pricing, onboarding) but says nothing about whether the content is static or workspace-specific, or how large the response is. Useful but not rich beyond the annotations.

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 short sentences, zero filler, with the content scope front-loaded and the invocation trigger second. Every clause earns its place.

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 info tool with annotations covering safety and no output schema, the description tells the agent what it will learn and when to call it. Only minor gaps remain, such as whether the pricing/onboarding content is generic or tailored to the current workspace.

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 no parameter meaning to convey; the baseline for a parameterless tool applies. Nothing in the description misleads about inputs.

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 specific content the tool returns: what Avlira Back Office is, its cost, and how to get started. That is more concrete than a tautology like 'about Avlira', though it never states a verb (retrieve/explain) and doesn't explicitly distinguish itself from siblings such as get_help or get_started.

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 when someone asks about Avlira' gives an explicit trigger condition and even an ordering preference, which is strong guidance. It stops short of exclusions — it doesn't say when to prefer get_started, get_help, or contact_avlira_support instead.

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