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

With zero annotations, the description carries the full burden, and it does disclose two non-obvious traits: an Authorization requirement and the accepted payment rails (trial, subscription, $1.99 x402). However, it says nothing about what "clearing" actually does — whether it deletes the contention event, is idempotent, is reversible, or what happens on failure.

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 front-loaded sentence with no filler and the auth requirement placed last where it is easy to scan. Its only flaw is being under-specified rather than wasteful, which is penalized under contextual completeness.

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?

For a tool with four required, entirely undocumented parameters, no annotations, and no output schema, one sentence is far short of what an agent needs to construct a valid call. Nothing in the definition explains the domain model the parameters encode.

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?

All four required parameters (resource, capacity, ceiling, claims) have 0% schema description coverage, and the description does not mention any of them. An agent has no way to know what value shape "resource" expects or how "capacity" and "ceiling" relate to "claims."

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?

It states a verb and a resource ("Clear one contention event") and adds that the event may be a trial, subscription allowance, or $1.99 x402 payment. But "contention event" and "clear" are the tool's own private vocabulary, so an agent cannot tell concretely what state changes or how this differs from gate_ledger and register_claim.

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?

"Requires Authorization" is a prerequisite, not usage guidance. There is no statement of when this tool should be chosen over the sibling tools gate_ledger or register_claim, and no exclusion conditions.

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