Create account database

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

Annotations only say readOnlyHint=false and destructiveHint=false. The description adds meaningful behavioral context: it creates three connected artifacts (database, user, password) and automatically prefixes names with the account username when needed. This goes beyond the structured hints, though it omits collision or failure behavior.

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 concise sentences: the first states the core operation and the second adds the key prefixing behavior. No filler or redundant restatement of the tool name.

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 five-param create operation with no output schema and minimal annotations, the description covers the main side effects and the notable prefix behavior. However, it does not describe return behavior, failure conditions, or account prerequisites, and it leaves the schema's tautological 'username parameter' unresolved.

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 reinforces the auto-prefix rule already present in the schema but does not clarify the weak 'username parameter' schema text or add meaning beyond what the schema fields already state.

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 clearly states the action and object: 'Creates a database with a database user and password for the specified account.' The account-level framing and automatic prefixing behavior help distinguish it from website-level database creation siblings, though it never names an alternative explicitly.

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?

The description implies account-level usage ('for the specified account') but provides no explicit when-to-use or when-not-to-use guidance, no prerequisites, and no named alternatives. An agent gets little help deciding between this and sibling database-creation tools.

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