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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety and idempotency profile is fully covered elsewhere. The description adds nothing beyond that: no behavior for a missing/invalid ID, no error semantics, and no indication of what the entry contains.

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, matching the low complexity of a one-parameter read. It is efficient but offers no additional structure or scoping note that a 5 would require.

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 one-parameter retrieval tool with rich annotations, the description is minimally adequate. With no output schema present, nothing tells the agent what fields a risk history entry returns or how an invalid ID is handled, which is a real but modest gap for this tool class.

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% with a single well-documented uuid parameter (format and regex pattern for the ID), so the schema carries the parameter burden. The description's 'by ID' merely restates what the schema already specifies and adds no format or sourcing guidance.

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 (Get) and resource (asset risk history entry) and adds the retrieval key (by ID), which is enough to distinguish a single-record fetch from list_asset_risk_history. It does not name that sibling explicitly, so the differentiation is inferable rather than stated.

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?

Usage is implied: the 'by ID' framing tells the agent this is a lookup that requires a known identifier, so enumerating tools are the implicit alternative. However there is no explicit when-to-use statement and no warning about confusing this with get_infrastructure_asset_risk_history_entry, which is a similarly named tool for a different asset family.

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