upgrade_list

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

No annotations are provided, so the description carries the full transparency burden. It discloses the one-time charge, the required env var, and the effect on limits. However, it does not mention whether the operation is reversible, what happens on failure, or if it is idempotent.

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?

Three brief sentences, each adding essential information: action & price, prerequisite, and effect. No wasted words; the description is well-front-loaded and easy to parse.

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's simplicity (single parameter, no output schema, no annotations), the description covers purpose, prerequisite, and effect. It could be more complete by mentioning the return value or error handling, but it is largely sufficient for agent selection and invocation.

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 100% for the single parameter, so the baseline is 3. The description adds no additional semantics for the list_id parameter beyond what the schema already provides, but it does add overall context about the upgrade's purpose.

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 ('Upgrade a punch list to Pro'), the resource (punch list), and the specific outcome (removes limits). It is distinct from all sibling tools, which handle CRUD and item management, not upgrades.

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 explicitly requires a Stripe payment method via environment variable, providing a clear prerequisite. It does not explicitly state when to avoid using the tool (e.g., if already Pro), but the context is sufficient for a single-purpose upgrade action.

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