subscriptions__record_subscription

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

With zero annotations, the description must disclose behavioral traits. It mentions idempotency and that a newly created account receives its key once. However, it does not clarify side effects (e.g., billing, charging), permission requirements, or error handling. Some transparency, but incomplete.

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 contains a bracketed prefix ('[subscriptions — B2B monthly seats...]') that is more like a category than essential info. The core is two sentences. The prefix could be removed without losing clarity, so it is not as concise as it could be.

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 tool has one parameter, no output schema, and no annotations, the description is minimally adequate. It explains the core action and idempotency. But it lacks details on response, errors, and prerequisites, which leaves the agent with some uncertainty.

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 input schema has 0% coverage (no parameter descriptions). The description only implies the parameter is a Stripe session or subscription ID through the action phrase 'Pull-verify a Stripe session/subscription.' It does not explain format, validation, or what constitutes a valid ID, so it adds minimal meaning beyond the parameter name.

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: 'Pull-verify a Stripe session/subscription and idempotently activate its exact subscription period.' It uses specific verbs (pull-verify, activate) and identifies the resource (Stripe session/subscription, subscription period). This distinguishes it from siblings like create_checkout_link or subscription_status.

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 provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, when not to use it, or how it relates to sibling tools like create_checkout_link or subscription_status. The context is purely operational.

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