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

Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so safety is covered, but the description adds nothing beyond them. It does not disclose what happens when the ID is not found, whether the entry includes historical metadata, or anything about the returned record.

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?

One short, front-loaded sentence with no filler or redundancy. It is efficient, though its brevity comes at the cost of substance rather than through disciplined editing of a richer description.

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 tool with complete annotations, the description is minimally adequate. Because there is no output schema, the agent gets no signal about the shape or fields of the returned risk history entry, which the description could have supplied.

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?

With a single parameter at 100% schema description coverage ('Risk history entry ID', uuid format), the schema carries the full semantic load. The description's 'by ID' adds nothing the schema does not already state, so the baseline 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 states a specific verb (get) and resource (asset risk history entry) and clarifies 'a single ... by ID', which lightly separates it from the list_asset_risk_history sibling. However, it essentially restates the tool title and gives no help distinguishing it from near-twin siblings such as get_infrastructure_asset_risk_history_entry.

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?

There is no guidance on when to use this tool versus the list_asset_risk_history or get_infrastructure_asset_risk_history_entry alternatives, nor any stated precondition (e.g., that an ID must come from a prior list call). Usage must be inferred 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.
