TDQS

A4/5.0
Behavior3/5

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

Annotations include destructiveHint=false, indicating the operation is not destructive. The description adds some context (ACL management, Redis/Valkey target) but does not disclose behaviors like idempotency, duplicate handling, or permission requirements. It carries reasonable burden given minimal annotation coverage, but lacks rich detail.

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 description is a single clear sentence with no redundancy. It front-loads the action and resource, making it easy to scan and understand.

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 straightforward add operation with fully described schema and a safety annotation, the description is adequate. It identifies the resource type and operation clearly. Minor gap: no mention of prerequisites (e.g., instance must exist) or whether the operation is synchronous, but these are not critical for tool selection.

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%, with all parameters (regionCode, cloudCacheUserList, cloudCacheInstanceNo) fully described including constraints. The description itself adds no parameter details, but the schema carries the semantic load. Baseline 3 is appropriate.

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

Purpose5/5

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

The description uses a specific verb 'Add' with a clear resource 'DB users (ACL) to a Cloud DB for Cache (Redis/Valkey) instance', distinguishing it from sibling tools like ncloud_change_cache_users and ncloud_delete_cache_users. The target service and operation are unambiguous.

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

Usage Guidelines4/5

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

The description clearly implies when to use this tool (to add new ACL users) without explicitly naming alternatives. It differentiates from sibling operations via the verb and resource, but lacks explicit 'use change_cache_users instead' type guidance. Context is clear but exclusions are not stated.

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