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

Annotations establish this is a write (readOnlyHint=false) that is idempotent and non-destructive; the description usefully discloses the scope of the side effect by stating the use count is the only signal a card carries. It does not say how repeat calls are handled or what validation occurs on the findingId, so it adds context without fully covering behavior.

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?

Two short sentences, purpose front-loaded with no filler. The all-caps phrasing and the second sentence are a slight style cost but nothing is wasted.

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 three-parameter recording tool with full schema coverage and an annotation set that carries the safety profile, this is adequate: purpose and effect scope are stated. It leaves gaps on call preconditions and repeat-call semantics, and there is no output schema to explain what the agent gets back.

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%, so the schema already documents slug, action and findingId, giving a baseline of 3. The phrase 'tied to the live finding it produced' adds a little meaning about which findingId is acceptable, but the 'live' and 'produced with this method' constraints are not spelled out as validation rules.

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 names a specific verb (report) and resource (a method card's usage), and ties it to the producing finding, so an agent can distinguish it from mint_method or list_methods. It stops short of explicitly naming a sibling, but the action is unambiguous.

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?

It conveys the point of the call ('the use count is the only signal a card carries') but never says when to make this call versus alternatives such as mint_method, or what preconditions apply (e.g. the finding must already exist and be live). The agent must infer the trigger condition.

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