TDQS

B3.4/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full behavioral-disclosure burden. 'Get' implies a read operation, but it says nothing about permissions, pagination, result size, or other operational traits; the output schema helps with return values, but the description itself is minimal.

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 definition is a single, front-loaded sentence with no wasted words. It states the resource and the optional filtering scope immediately.

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

Completeness4/5

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

For a simple read tool with one optional, fully documented parameter and an output schema, the description supplies enough context to invoke it correctly. The main gap is the absence of guidance on when to prefer this tool over related L7 rules or listener tools.

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?

Schema description coverage is 100%, so the listener_name_or_id parameter is already fully documented as optional and empty-means-all. The description mirrors that behavior ('for a listener or all L7 policies') but does not add format, identification, or filtering details beyond the schema.

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

Purpose4/5

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

The description states a specific verb and resource (Get L7 policies) and gives the scope (for a listener or all policies). It is clear enough to distinguish from siblings like get_load_balancer_l7_rules by resource name, though it does not explicitly call out when this tool should be chosen over that sibling.

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

Usage Guidelines3/5

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

The description implies the optional filter behavior: pass a listener to scope policies, or omit it to retrieve all. It does not state when to use this tool versus alternatives such as get_load_balancer_l7_rules or get_load_balancer_listeners, so the usage guidance remains implicit.

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