TDQS

A3.6/5.0
Behavior3/5

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

No annotations are provided, so the description carries the burden; 'Get' implies a safe read, but it says nothing about permissions, pagination, or behavior when the policy has zero rules. An output schema exists, which relieves it of explaining return structure, so the remaining gap is moderate rather than severe.

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?

One short sentence, front-loaded with the verb and resource, with the scoping condition stated immediately. There is no filler to trim.

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 single-required-parameter read tool with full schema coverage and an output schema, the description covers what is needed to select and call it. Only the absence of any hint about empty-result behavior keeps it from being fully complete.

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% and the single parameter is already documented as 'L7 policy name or ID (required)'. The description only restates that the value identifies a specific policy, adding no format, lookup, or resolution semantics 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 ('Get') and resource ('L7 rules') scoped to an L7 policy, which distinguishes it from the sibling get_load_balancer_l7_policies that returns policies rather than rules. It stops short of explicitly naming that sibling or contrasting the two.

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?

Mentioning 'for a specific L7 policy' implies a policy identifier is required and that this is a drill-down call after listing policies, but it never states when to use this versus get_load_balancer_l7_policies or what happens if the policy has no rules.

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