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

With no annotations, the description carries the burden and does reasonably well: it discloses that the operation is paid, that missing authorization returns a payment challenge, that success is a 202 carrying a poll_url, and that polling and re-paying are unnecessary. It still omits the cost of the pass itself and what it returns beyond the poll handle.

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 short, front-loaded sentences with no filler: purpose first, then the payment-challenge behavior, then the polling caveat. Tight, though the opening phrase is so terse it underspecifies rather than economizes.

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 five parameters, 20% schema coverage, no annotations, and no output schema, the description should explain the naming operation and its inputs. It covers only the payment/poll plumbing and leaves the core action and four parameters unexplained.

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 only 20%, and only "authorization" is documented in the schema. The description ties authorization to the 402 challenge, which is genuinely useful, but brief, product, customer, and rejected are never explained anywhere, leaving most parameters opaque.

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?

"Paid naming pass" largely restates the tool name (name/naming) and adds only the payment qualifier. It never says what a "naming pass" produces from the brief, nor how it differs from siblings hero and poll, so an agent cannot tell what this tool actually does.

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 gives real procedural guidance for the payment loop (no authorization yields the challenge; a 202 gives a poll_url; don't pay twice), which implies the poll sibling follows. However, it never states when to choose this tool over hero or poll, so selection guidance is only implied.

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