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 but offers minimal insight. It mentions '[application delivery]' as context but doesn't explain whether this is a mutating operation, its side effects (e.g., if it triggers deployments), permission requirements, or error handling. This leaves critical behavioral traits unspecified.

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 brief and front-loaded with the core action, consisting of a single phrase. However, it lacks structure (e.g., no separation of purpose from context) and could be more informative without sacrificing conciseness, as it currently under-specifies key details.

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 of a mutating operation (adding hosts to a deploy group) with no annotations and no output schema, the description is incomplete. It fails to address behavioral aspects like mutation effects, return values, or error conditions, leaving significant gaps for an AI agent to understand the tool's full context.

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?

The schema description coverage is 100%, with clear parameter descriptions in Chinese (e.g., '组织ID' for organizationId). The tool description adds no additional parameter semantics beyond what's in the schema, so it meets the baseline score of 3 for adequate but not enhanced coverage.

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 states the action ('Add host list') and target ('to deploy group'), which clarifies the basic purpose. However, it's vague about what 'add' entails (e.g., appending vs. replacing) and doesn't distinguish it from the sibling tool 'add_host_list_to_host_group', leaving ambiguity about when to use one over the other.

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?

No guidance is provided on when to use this tool versus alternatives like 'add_host_list_to_host_group' or other deployment-related tools. The description lacks context about prerequisites, dependencies, or typical scenarios for adding hosts to a deploy group.

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