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 states 'Get all', implying a read-only operation, but doesn't disclose behavioral traits like pagination handling (given skip/limit parameters), authentication requirements, rate limits, or what 'all' entails (e.g., scope, permissions). For a tool with parameters and no annotations, this is a significant gap.

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 a single, efficient sentence with no wasted words. It's front-loaded with the core purpose, making it easy to scan and understand quickly.

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 (3 parameters, no schema descriptions, no annotations, no output schema), the description is incomplete. It states the basic purpose but fails to address parameter usage, behavioral context, or output expectations, leaving critical gaps for the agent to operate effectively.

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%, meaning none of the three parameters (skip, limit, nameFilter) are documented in the schema. The description adds no information about these parameters—it doesn't explain what they do, their expected values, or how they affect the 'Get all' operation. This leaves the parameters completely undocumented.

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 verb ('Get') and resource ('all VMware vSphere snapshot replicas'), making the purpose specific and understandable. However, it doesn't differentiate from sibling tools like 'GetReplica' or 'GetAllObjectReplicaRestorePoints', which appear to fetch related but potentially different data.

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 no guidance on when to use this tool versus alternatives like 'GetReplica' or 'GetAllObjectReplicaRestorePoints'. There's no mention of prerequisites, context, or exclusions, leaving the agent with no usage direction beyond the basic purpose.

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