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

Annotations already declare readOnlyHint=true, openWorldHint=false, and destructiveHint=false, so this is unambiguously a safe local read. The description adds nothing beyond that safety profile — no indication of return format, whether it is static documentation or dynamic state, or how it relates to the other reference tools.

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?

A single front-loaded sentence with no wasted words. Slightly generic in 'product workflow', but structurally efficient.

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 simple parameterless read tool with annotations and no output schema, the description is minimally adequate. It does not, however, say what the agent gets back or why this differs from the other overview/reference siblings, which is the main remaining gap.

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; the baseline for a parameterless tool applies. No parameter-related gaps exist.

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 a specific scope (sign up, connect an agent, begin the product workflow), so an agent can tell this is an onboarding/quickstart resource rather than a search or reference tool. However, it offers no explicit differentiation from siblings like product_overview or pricing_reference, which could also plausibly cover 'getting started' material.

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?

There is no statement of when to call this versus product_overview, pricing_reference, or product_search, and no prerequisites or exclusions. Usage is only weakly implied by the 'sign up / connect an agent' phrasing.

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