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

Annotations already declare readOnlyHint, idempotentHint and destructiveHint=false, covering the safety profile. The description adds useful scoping context by clarifying that transfer and approval are out of scope. It does not, however, describe pagination behavior or what "current versions" resolves to, so the added value is modest.

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?

Two short sentences, no filler, with the primary purpose front-loaded ahead of the scoping note. Every sentence earns its place.

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, read-only list tool whose annotations already convey safety, the description is minimally adequate. The gaps are pagination behavior and the meaning of "current versions," neither of which is covered elsewhere since there is no output schema.

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% and both parameters (limit, offset) are undocumented in the schema, so the description carries the burden of explaining them. It says nothing about pagination, defaults, or max values, leaving the agent to infer semantics from parameter names alone.

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 (List) plus resource (evidence records and current versions), so the agent knows exactly what it retrieves. It does not distinguish itself from close siblings like list_document_versions or read_evidence_review, but the core purpose is unambiguous.

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?

"File transfer and evidence approval are separate operations" scopes the tool by excluding adjacent concerns, which implies the agent should look elsewhere for uploads and approvals. However, it never names the alternative tools (e.g., create_evidence, add_evidence_version) or states the condition that selects this one, leaving usage context inferred.

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