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

With no annotations, the description carries the full behavioral burden. It usefully discloses a $0.02 cost and X-PAYMENT mechanism, but it omits permissions, side effects, idempotency, whether the override is reversible, and what happens after filing.

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?

It is a single front-loaded sentence with no filler, but it is under-specified for a 3-parameter mutation tool. Conciseness here comes at the cost of necessary detail.

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?

The description names the operation and payment cost, but given no annotations, no output schema, and 0% parameter documentation, it leaves critical information missing for safe invocation. It is not complete enough for an agent to call this tool confidently.

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?

There are 3 parameters with 0% schema description coverage, and the description does not explain tool, task_class, or reason_code. It provides no meaning beyond the parameter names in the schema.

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 and resource: "File a DAW override." This is more specific than a vague action, but the acronym DAW is unexplained and the description does not explicitly differentiate it from siblings such as formulary_dispense or formulary_report_failure.

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 no when-to-use guidance, prerequisites, or alternatives. An agent can infer that this tool is used when filing a DAW override, but nothing says when to choose it over report_failure, verify_receipt, or other sibling tools.

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