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

Annotations already declare readOnlyHint=true, so the description does not need to establish safety. It adds useful content expectations but no behavioral traits beyond what the annotations and schema indicate, such as error behavior, availability of associated documents, or whether details can be partial.

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, compact sentence that front-loads the core purpose ('Get full details of a specific enforcement action') and then efficiently lists the kind of information returned. Every phrase earns its place with no redundancy.

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 simple, single-parameter, read-only detail-fetch tool, the definition is complete: the input is well specified, the annotations clarify safety, and the description enumerates the return contents even in the absence of an output schema. An agent has enough context to invoke it correctly.

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 description coverage is 100%, and the sole parameter event_id is already documented as 'The UUID or public slug of the enforcement event.' The description adds no parameter-level detail beyond the schema, so the baseline of 3 applies.

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 uses a specific verb ('Get') with a specific resource ('full details of a specific enforcement action') and enumerates distinct content areas (laws cited, remedies, source quotes, document URLs). It clearly differentiates from siblings like search_enforcement_actions, which is for finding actions, and get_enforcement_stats, which is for aggregated data.

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 wording 'specific enforcement action' and the required event_id imply the tool is for retrieving one known entity, but it does not explicitly state when to use it over search_enforcement_actions or how to obtain a valid event_id. Usage context is reasonable but left to inference rather than stated.

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