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

No annotations are provided, so the description carries the full burden. It mentions the tool retrieves sessions with status, progress, and result, but does not disclose behavioral traits such as pagination (implied by skip/limit parameters), authentication needs, rate limits, or whether it's a read-only operation. The description is minimal and lacks critical operational context for a tool with 13 parameters.

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?

The description is concise and front-loaded: two sentences that directly state the purpose and usage. There is no wasted text, and it efficiently communicates core information without unnecessary details.

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?

Given the complexity (13 parameters, no annotations, no output schema), the description is incomplete. It covers basic purpose and a hint of usage but lacks parameter explanations, behavioral details, and output information. For a tool with extensive filtering capabilities, this is insufficient to guide effective use.

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?

The input schema has 13 parameters with 0% description coverage, and the tool description does not mention any parameters or their semantics. It fails to compensate for the lack of schema documentation, leaving all parameters undocumented. This is inadequate for a tool with many filtering options.

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?

The description clearly states the tool's purpose: 'Get all backup/restore sessions with status, progress and result.' It specifies the verb ('Get'), resource ('backup/restore sessions'), and key attributes returned. However, it does not explicitly differentiate from sibling tools like 'GetAllTaskSessions' or 'GetAllAutomationSessions', which might have overlapping functions, so it lacks full sibling differentiation.

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 provides some usage context: 'Use this to check SLA and job health.' This implies the tool is for monitoring and health checks, but it does not specify when to use this tool versus alternatives (e.g., other 'GetAll' tools for sessions), nor does it mention prerequisites or exclusions. The guidance is implied rather than explicit.

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