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

Adds genuine behavioral context beyond the annotations: the required human-consent sequence and the ordering constraint relative to account creation. The 'Read-only' statement is largely redundant with readOnlyHint=true, and no return format or pagination detail is given, but for a zero-param read tool the extra workflow disclosure is substantive.

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?

Three short sentences with no filler, and the most important constraint (get a clear yes before creating an account) is front-loaded immediately after the purpose statement.

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 tool with annotations covering the safety profile and no output schema, the description supplies everything an agent needs: what it returns, the consent workflow, and the ordering relative to sebbi_create_account.

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, so the baseline is 4. The description correctly adds nothing about inputs because there are none, and it instead describes output content (terms and version).

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?

States a specific verb+resource (returns the service terms and their version) in the first sentence. It is clearly distinguishable from the sibling sebbi_create_account, which it explicitly names, so an agent knows exactly what this tool does without opening the schema.

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?

Gives explicit sequencing ('before calling sebbi_create_account') and an explicit precondition ('show the full text to the person and get a clear yes'). This is a when-to-use rule with a required workflow, not just an implied context.

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