get_account

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

No annotations exist, so the description carries the burden; 'Get' implies a safe read but that is only inferred, and nothing is said about authentication scope or account-scoping (the API key owner). It does disclose the returned subject matter (details, quota, plan), which is more than nothing for a zero-argument tool.

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 short sentence with no filler, front-loading the resource and enumerating the payload in order of importance. Nothing here wastes an agent's context.

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 is the only source of return-value information, and 'details' remains vague beyond quota and plan. It also omits any mention of credentials/scoping, which is the one thing an agent must understand for a parameterless account call that overlaps with get_subscription.

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 tool takes zero parameters, so there is nothing to disambiguate; baseline 4 applies. The description correctly implies the account is derived from credentials rather than passed in.

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 and resource ('Get account details') and enumerates the payload (quota usage, plan), so the agent knows exactly what comes back. It does not distinguish itself from siblings such as get_subscription or list_billing_plans, which cover overlapping 'plan' territory.

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?

No guidance on when to call this versus get_subscription or list_billing_plans, which are the obvious near-duplicates in the sibling list. There are no stated prerequisites or exclusions.

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