paywall_get_tenant

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

No annotations are provided, so the description carries the full behavioral burden. It does disclose one genuinely useful fact outside the (empty) schema: the call requires PAYWALL_API_KEY. However, it says nothing about whether the operation is read-only, what the tenant record contains, or how auth failures surface.

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 the grouping tag '[x402 Paywall]' front-loaded and the auth prerequisite appended. Nothing is wasted, though the terse phrasing leaves the reader with only a name-level understanding.

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?

With no output schema and no annotations, the description is the only source of information about this call, and it stops short of describing what a tenant record contains or what happens on a missing/invalid key. Adequate for a zero-parameter read, but thin for a tool whose output shape is otherwise undocumented.

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 no parameter semantics to convey; the baseline for a parameterless tool is 4. The description correctly implies no inputs are required.

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 (get) and resource (tenant record) and adds the scoping word 'Your,' clarifying this returns the caller's own tenant rather than an arbitrary one. It is clear but offers no explicit differentiation from the other paywall_* siblings beyond the resource name.

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 when-to-use guidance, no mention of alternatives, and no conditions under which this should or should not be called. The only guidance is the parenthetical prerequisite '(needs PAYWALL_API_KEY)', which is a requirement rather than usage direction.

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