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

Annotations already declare readOnly/idempotent/non-destructive/closed-world, but the description goes further with an explicit negative list: it does not create a business, save account records, start work, deploy a website, or charge money. It also discloses statelessness and the email sign-in step in Baron, which annotations cannot convey.

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?

Front-loaded purpose followed by usage, return values, and scope exclusions in a logical order. Slightly long, and the closing note about directory examples being 'inspiration, not guarantees' is tangential, but no sentence is wasted.

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?

There is no output schema, so the description carries the return burden and does: the complete brief, a prefilled review-form link, and remaining setup questions. Combined with the precondition and scope-exclusion statements, an agent has everything needed to invoke this correctly.

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% and each of the four fields is documented in the schema, so the baseline is 3. The description only restates that 'name' is optional and that missing required details should be gathered first, adding little semantic detail beyond what the schema already provides.

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+resource ('turning their idea into a short business brief') and clearly bounds the scope as a preparation step. It gestures at the directory/examples that the sibling find_businesses serves, but never names that sibling, so differentiation is only implicit.

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?

Strong explicit preconditions: 'Use after they identify the customer, paid offering, and delivery method; ask for missing details before calling.' It also states a sign-in prerequisite. It stops short of naming an alternative tool or a when-not-to-use condition, so not a full 5.

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