list_security_group_rules

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

As a listing operation, it is likely read-only, but the description does not confirm this or disclose any behavioral traits. With no annotations, the description should explicitly state the operation's safety, pagination behavior, or any side effects. The current description is vague and does not add value beyond the bare action.

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 very concise at one sentence. It is front-loaded with the essential action. While it could be expanded slightly without losing conciseness, it currently has no wasted words.

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?

The tool lacks an output schema, so the description should clarify what is returned (e.g., a list of rule objects). Without this, an AI agent cannot fully understand the tool's effect. The description is incomplete regarding return value and structure.

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?

Both parameters are fully described in the input schema (100% coverage), so the schema already provides their meaning. The tool description adds no additional context or syntax details, warranting the baseline score of 3.

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 lists all rules within a specific security group. It uses a specific verb (list) and resource (rules in a security group), effectively distinguishing it from siblings like list_security_groups (which lists groups) and get_security_group_rule (which retrieves a single rule).

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 get_security_group_rule. The description does not mention prerequisites (e.g., existence of datacenter and security group) or scenarios where this tool is appropriate.

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