create_trial_account

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

No annotations exist, so the description carries the full burden. It discloses an important behavioral trait: the account requires email verification after creation, with the user needing a verification code. This goes beyond a simple 'create' and helps the agent anticipate the follow-up.

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 sentences, front-loaded with purpose, then usage condition, then next step. Every sentence adds value with no redundancy or filler.

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?

The description provides purpose, when to use, and the critical post-creation step (email verification). While there is no output schema, the description does not detail response/error handling, but for a workflow-oriented create tool, it is sufficiently complete.

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?

Schema description coverage is 100%, so the baseline is 3. The description only generically says 'Collects their info' without adding specific parameter semantics, but the schema already fully documents each parameter.

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 opens with 'Create a free AdButler trial account', a specific verb+resource statement. It clearly distinguishes from siblings by stating 'Use this when the user does NOT have an AdButler account yet', and even names the follow-up tool verify_trial_email.

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?

Explicit usage condition: 'Use this when the user does NOT have an AdButler account yet.' It also provides the necessary next step, directing the user to verify_trial_email, which serves as a clear workflow guideline.

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