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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and a closed-world scope, so the safety profile is covered. The description only restates the read nature ("Read") and adds no context such as ordering, whether the list is complete, or what a 'decision' record contains, so it earns little credit beyond annotations.

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 zero filler. It is efficient, though the brevity borders on under-specification rather than optimal concision.

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?

An output schema exists, so return values need not be explained, but with 0% parameter coverage and an undefined domain term ("decisions"), the definition leaves the agent missing the pagination contract and the meaning of the returned records for a required-filter list tool.

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 0% with three parameters, so the description must compensate but does not: limit and offset are never mentioned, and the required lawEventId is only obliquely implied by "about a law event". No format, defaults, or pagination semantics are supplied.

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 verb ("Read") and a resource ("documented decisions about a law event"), so the agent knows it returns a list of decisions scoped to a law event. However, "decisions" is never defined, and the description does not distinguish it from nearby siblings such as list_law_events, list_law_notes, or get_law_event.

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?

No guidance on when to use this versus get_law_event, list_law_events, or list_law_notes, and no prerequisites (e.g., needing an existing lawEventId). The agent must infer usage entirely from the name.

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