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

Annotations declare readOnlyHint=true and destructiveHint=false, but the description instructs the agent to 'create a TaleSpinner account', which reads as a state-mutating write. The description contradicts the declared safety profile and adds no other behavioral context (no return format, auth needs, or side effects).

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 compact sentence with no wasted words, and the onboarding intent is front-loaded. It is efficient, though its brevity is partly the source of its ambiguity.

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 full burden of explaining what this 0-arg tool returns or triggers. One sentence about account creation leaves the agent unsure whether it mutates state, returns instructions, or what to do next — and its conflict with the readOnly annotation compounds the 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 0-param tool is 4.

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 goal (help a new customer create an account) that the vague name 'get_started' does not convey, so it adds some clarity. However, it never states what the tool actually does mechanically — return onboarding instructions, launch a signup flow, or mutate state — and it does not distinguish itself from siblings like get_account or create_story.

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 phrase 'before connecting it to the assistant' gives an implied sequencing cue for when this tool applies in the onboarding flow. It offers no explicit alternatives or when-not-to-use guidance, so the agent must infer the rest.

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