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

Annotations already declare readOnly, idempotent, non-destructive and closed-world, so the safety profile is covered. The description usefully adds the shape of the return payload (the record's constituent fields), which matters here because there is no output schema; it does not address missing-record or error 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?

One sentence, no filler, and the key operation and identifier example are front-loaded. Every clause earns its place by describing what the record contains.

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 one-parameter read tool with no output schema, the description carries the return-value burden and does so by enumerating the record's fields. Only the failure/not-found case is unaddressed, which is a minor omission for a retrieval 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 coverage is 0% and the single parameter is bare, so the description must compensate — and it does, supplying a concrete ID example ('SEA-POST-005') that conveys the expected identifier format. It stops short of stating whether the ID is case-sensitive or the exact matching 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?

Clear verb+resource: 'Full record for one incident by ID' plus an enumeration of the returned content (what happened, source, failure pattern, safeguards, review status). It reads as distinct from search_incidents by framing itself as a single-record lookup, but it never names the sibling explicitly.

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 only implied: the 'by ID' framing signals this is the retrieval path once an ID is known, versus search_incidents for discovery. There is no explicit statement of when to prefer this tool, nor any exclusion or prerequisite (e.g. what happens if the ID is unknown).

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