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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds the meaningful scope constraint that private narratives and the public web are excluded, reinforcing openWorld=false, but says nothing about result limits, ranking, or pagination 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?

Front-loaded purpose sentence, then dense syntax documentation, then a closing exclusion. Every sentence earns its place; only the trailing 'common incident, claim, task, audit and inspection terms' is slightly vague.

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 search tool with a full annotation set, the description covers purpose, scope boundaries, and query grammar. It does not describe the shape of returned results or any result cap, but with no output schema and a citation-oriented framing that is a minor gap.

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%, so the description carries the full burden for the single 'query' parameter — and it does: it documents the module: filter with its five allowed values, id:, status:, priority:, location:, the bare 'overdue' token, and free-text term support. This is well beyond what the bare string schema provides.

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?

Specific verb+resource: searches 'accessible IncidentVault operational record sources for citations'. Scope is stated clearly enough to distinguish it from fetch (retrieve a known record) and check_action, though the overlap with find_records is not addressed.

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 description implies when to use it by enumerating what is searchable and explicitly excluding private narratives and the public web. However, it never names an alternative sibling (find_records, fetch) or states the condition that selects one over the other, so routing is left to inference.

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