aws_resource_list

Read-onlyIdempotent

List AWS resources of a specified CloudFormation type with pagination, using Cloud Control API. Supports parent identifiers for nested resources and returns results with a continuation token.

Instructions

List resources of a given type via Cloud Control API, paginated. Returns an array of {identifier, properties}, a nextToken (null when exhausted), and hasMore. Some types need parent identifiers (e.g. nested resources under a cluster); pass those as resourceModel.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
typeNameYesCloudFormation type name, e.g. 'AWS::Lambda::Function'.
resourceModelNoParent identifier properties for nested types, e.g. {ClusterArn: '...'}.
maxResultsNoPage size (1-100). Default 100.
nextTokenNoResume cursor from the previous call's `nextToken`. Omit for the first page.
profileNoOverride session profile for this call.
regionNoOverride session region for this call.
timeoutMsNoTimeout in milliseconds. Default 60000.
Behavior4/5

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

Annotations already indicate readOnlyHint=true and destructiveHint=false. The description adds useful context about pagination behavior, return structure, and the need for parent identifiers in nested types. There is no contradiction with annotations.

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 extremely concise with three sentences: one for purpose, one for output format, and one for special case. It is front-loaded and contains no redundant information, earning its place efficiently.

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?

Given the complexity of 7 parameters and no output schema, the description covers the return shape, pagination, and parent identifier scenario. It lacks discussion of error handling or when to prefer this over sibling tools, but overall is fairly complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with well-described parameters. The description enriches this by explaining that resourceModel is for parent identifiers in nested resources, adding value beyond the schema's generic description.

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 clearly states the tool lists resources of a given type via Cloud Control API with pagination. It specifies the return format and distinguishes itself from sibling tools like aws_resource_get by focusing on listing multiple resources.

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

Usage Guidelines2/5

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

The description does not provide explicit guidance on when to use this tool versus alternatives such as aws_resource_get or aws_resource_create. It only implies usage through the verb 'list' and mention of parent identifiers, but no direct comparison or context.

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