Brainstorm brandable domains

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

Annotations declare readOnlyHint=true and openWorldHint=true, so safety is covered; the description usefully adds that results are ranked by length/pronounceability and that availability is checked live across TLDs. It also implies network activity consistent with openWorldHint. It stops short of noting lookup limits (visible only in the 'check' schema description).

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 front-loaded sentence names the primary action first, then folds in strategies, ranking, and the availability/pricing follow-on. Dense but readable, with no filler sentences.

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 5-param tool with no output schema and annotations already covering the safety profile, the description conveys the core behavior (generation strategy, ranking, live availability, prices). Remaining gaps around lookup limits and per-parameter behavior are minor.

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 coverage is 60%, and the description only maps loosely to params: 'product idea' aligns with idea and 'across TLDs' with tlds. It says nothing about count, check, or extraWords, leaving those to the schema. Baseline 3 is appropriate given partial coverage.

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 ('Generate') and resource ('brandable name ideas'), plus the secondary function of availability checks and pricing. It lists the generation strategies, which makes the tool's output concrete. It does not name or distinguish itself from siblings like check_availability or tld_pricing, even though it overlaps with 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?

Usage is implied: use this when you have a product idea and want generated names plus availability/pricing. There is no explicit when-to-use or when-not-to-use guidance, and no routing to alternatives such as check_availability for tools that only need a lookup.

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