A3.9/5.0

Behavior3/5

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds context about tenant-wide scope and that it is not group-scoped, which is useful, but it does not disclose pagination behavior or response structure beyond mentioning 'pagination' as an optional filter. Given the strong annotation coverage, this is acceptable but not exceptional.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is exactly two sentences, front-loaded with the core action and scope, followed by usage guidance and the alternative tool. No wasted words; every clause earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

While the tool has a rich output schema and annotations cover safety, the description does not adequately explain the many filter parameters or pagination semantics. The schema coverage is 0% and the description only hints at a few filter types, so an agent cannot reliably construct a well-formed query without additional context. The alternative routing and scope are helpful, but the parameter space is under-documented for a tool of this complexity.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description carries the burden of explaining the filter object's many fields. The description only mentions 'state, dates, pagination' as examples, which are vague and do not map cleanly to the actual property names (e.g., status, capturedFrom/capturedUntil, page/size). It fails to mention numerous other filters like id, hash, type, title, groupId, fileName, fileSize, metadata, groupType, caseFileId, custodyType, testimonyMode, and collectionMetadata, leaving the agent under-informed for constructing effective queries.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a clear verb ('Searches') and resource ('evidences across the tenant'), specifies scope ('not scoped to one group'), and names the primary use cases (find an evidenceId, audit what exists). It explicitly differentiates itself from the sibling tool evidence_group_get, so an agent can distinguish them without opening schemas.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives explicit when-to-use guidance ('Use to find an evidenceId or audit what exists') and a direct when-not-to-use with an alternative ('for one group's content use evidence_group_get instead'). This fully routes the agent to the correct tool for the two main scenarios.

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