dcs_security_groups

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

The readOnlyHint annotation already establishes that this is a safe read, and the "[READ]" prefix merely repeats that. Beyond the annotation, nothing is disclosed about pagination behavior, whether the default limit of 100 truncates results, or what fields each security group record contains.

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?

One short, front-loaded sentence with zero padding, so it is efficient. However, the brevity borders on under-specification rather than true conciseness given that a parameter and the return shape go unaddressed.

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?

There is no output schema and no annotation covering returns, so the description is the only place to explain what a listed security group looks like and how paging works, and it does neither. For a collection-list endpoint the definition is too thin to call confidently.

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 single parameter 'limit' has 0% schema description coverage and the description does not mention it at all, so an agent gets no meaning for it beyond its name and default of 100. This leaves the only tunable input undocumented in both places.

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 gives a specific verb (List) and resource (security groups), so an agent knows exactly what it does. It does not differentiate from siblings such as dcs_security_group (singular) or dcs_security_group_stats, which would be the natural next step.

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 when-to-use guidance and no mention of alternatives; the agent must infer from the plural name that this is the collection-listing call versus the singular detail call. There are no prerequisites or exclusions stated.

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