subscriptions__describe_agent

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

With no annotations, the description bears full burden. It implies a read-only operation but does not disclose authentication needs, rate limits, or potential side effects. The listed return items provide some transparency, but behavioral aspects are not addressed.

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?

The description is concise (two lines) and front-loaded with a domain prefix. However, the bracket format is unconventional and could be more streamlined. Every sentence provides useful information.

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?

Given no output schema, the description attempts to list return items but does not explain terms like 'fleet-standard version' or 'catalog digest', leaving some ambiguity. It is adequate but not fully complete for an agent to know exactly what each field means.

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?

There are zero parameters, so schema coverage is 100%. The description adds meaning by detailing the return values, which compensates for the lack of parameter info. It clarifies what the tool outputs beyond the empty schema.

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 starts with a domain prefix ('subscriptions — B2B monthly seats, entitlement quota, overage, and MRR') that differentiates it from other describe_agent tools. It clearly states it returns specific items like fleet-standard version and catalog digest, providing a clear purpose.

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?

There is no guidance on when to use this tool versus the many sibling describe_agent tools. The description only states what it returns, not in which context it should be chosen over alternatives.

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