Open TextVerified local setup

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=false, so the safety profile is known. The description adds genuinely useful lifecycle information beyond that: the localhost service shuts itself down after saving, which matters for an agent sequencing calls. It writes credentials, consistent with 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, no filler, with the core action stated first and the lifecycle constraint second. Nothing needs trimming.

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?

An output schema exists, so return values need not be described, and the description covers the action and the ephemeral service lifecycle. What is missing is the setup context an agent would need: what credentials are expected, whether user interaction at the browser is required, and any prerequisite state.

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 single parameter open_browser has 0% schema description coverage, so the description must compensate and does not — the parameter is never mentioned. The name and default (true) are intuitive, which keeps this above a 1, but a 'false' behavior is left unexplained.

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 gives a specific verb and resource: launching a one-shot localhost form for TextVerified credentials. That is clearly distinct from the API-style siblings (send_sms, settings_update, etc.), though it never explicitly says how it relates to them.

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?

'One-shot' implies it is used once, during initial setup, rather than repeatedly. However, there is no explicit when-to-use statement or exclusion, e.g. how it relates to textverified_settings_update or when credentials must be re-entered.

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