subscriptions__create_account

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

There are no annotations, so the description carries full burden. It discloses that the full account key is returned only once and that only its SHA-256 and last four characters are retained—an important security detail. However, it does not mention idempotency, permissions, error states, or side effects, leaving gaps in behavioral transparency.

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 extremely concise: two sentences with no wasted words. It front-loads context in brackets and then states the function and key security detail. Every sentence adds value.

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 the lack of output schema, the description explains the return of the full account key and its hash retention, which is useful. However, it omits potential error conditions, prerequisites, or how the account is used later. For a create action, completeness is adequate but not thorough.

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 0%, so the description must compensate. The only parameter, account_ref, is not explained at all. The description fails to add meaning to the parameter, leaving the agent without guidance on what value to provide.

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 tool creates a free account for bearer attribution, with a context prefix about subscriptions and B2B monthly seats. It uses a specific verb and resource, but could be more precise about what 'bearer attribution' entails. It differentiates from sibling tools like record_subscription and create_checkout_link by focusing on account creation.

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 does not provide explicit guidance on when to use this tool versus alternatives. It lacks information about prerequisites, suitability, or exclusion criteria. The sibling tools include other subscription management functions, but no comparison or use-case hints are given.

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