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. The description adds the HTTP method and endpoint path ([GET /v1/...]), but this is minimal additional context. No further behavioral details (e.g., authorization requirements, error handling) are provided beyond the annotations.

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 very concise—one main sentence plus an endpoint path. It front-loads the purpose without any extraneous information. Every part is necessary and earns its place.

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

Completeness5/5

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

Given only one parameter, no output schema, and annotations that fully describe the behavior (read-only, idempotent, non-destructive), the description is complete. It adequately informs the agent of the tool's function and endpoint without missing critical details.

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

Parameters3/5

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

The input schema has 100% coverage with one required 'id' parameter described as 'Resource identifier.' The description does not add any additional meaning or context about the parameter (e.g., format, source, constraints). Thus, it meets the baseline but adds no extra value.

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 clearly states 'Read one app encryption declaration document by ID', specifying a specific verb ('read'), resource ('app encryption declaration document'), and identifier method ('by ID'). This distinguishes it from sibling tools like create, update, or list operations.

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives. There are sibling tools for creating, updating, and listing documents, and no explicit conditions or exclusions are mentioned. The context of 'read by ID' is implied but not differentiated from similar queries.

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