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

With no annotations provided, the description carries the full burden of behavioral disclosure. It mentions validation via an endpoint but lacks critical details: whether this is a read-only operation, if it has side effects (e.g., logging), authentication requirements, rate limits, or what happens on failure (e.g., error messages). For a validation tool with zero annotation coverage, this is insufficient to inform the agent about behavioral traits.

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 zero waste. It front-loads the core action ('Validate service binding parameters') and includes essential details (parameters and endpoint) without redundancy. Every word earns its place, making it highly concise and well-structured.

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 (a validation tool with 5 parameters) and lack of annotations and output schema, the description is incomplete. It doesn't explain what the validation entails (e.g., checks for syntax, dependencies, or conflicts), what the return value might be (e.g., success/failure, error details), or behavioral aspects like idempotency. For a tool without structured support, more descriptive context is needed.

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 100%, so the input schema already documents all parameters thoroughly. The description lists the parameters (name, service definition, package, version) but doesn't add meaningful semantics beyond what the schema provides (e.g., validation rules or interdependencies). This meets the baseline of 3 when the schema does the heavy lifting, but no extra value is added.

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: 'Validate service binding parameters (name, service definition, package, version) via ADT validation endpoint.' It specifies the verb ('validate'), resource ('service binding parameters'), and method ('via ADT validation endpoint'), making the action clear. However, it doesn't explicitly differentiate from sibling tools like 'CreateServiceBinding' or 'UpdateServiceBinding', which would require a 5.

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. It doesn't mention prerequisites (e.g., whether the service binding must exist), contrast with siblings like 'CreateServiceBinding' (for creation) or 'GetServiceBinding' (for retrieval), or specify scenarios where validation is needed (e.g., before creation or updates). This lack of contextual direction leaves the agent to infer usage.

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