Instructions

Run all security scanners in parallel (including service detection). Read-only. Does not modify any AWS resources. Supports multi-account org scanning.

Input Schema

NameRequiredDescriptionDefault
langNoReport language (default: zh)
regionNoAWS region to scan (default: server region)
org_modeNoEnable multi-account scanning via AWS Organizations
providerNoCloud provider to scan (default: aws). With huaweicloud, `region` is a Huawei Cloud region ID (e.g. cn-north-4); omit it or pass "all" to scan every region project of the account. Huawei Cloud Phase 1 is single-account (org_mode falls back to the current account with a warning).
role_nameNoIAM role name to assume in child accounts (default: AWSSecurityMCPAudit)
account_idsNoSpecific account IDs to scan (default: all org accounts)

A3.7/5.0
Behavior4/5

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

With no annotations provided, the description carries the burden of behavioral disclosure. It explicitly adds 'Read-only. Does not modify any AWS resources' and notes parallel execution and multi-account org scanning, which are useful behavioral facts not present in the schema.

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 short, front-loaded, and every sentence carries useful information: scope, parallelism, safety, and org-mode support. There is no padding or repetition.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description gives a solid high-level picture: complete for invocation, but since there is no output schema and no annotations, it does not explain what the tool returns or how it relates to scan_and_report. It is adequate but not fully comprehensive for agent decision-making.

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%, so the schema already documents all six parameters. The description adds no parameter-specific semantic detail beyond schema, matching the baseline expectation.

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

Purpose4/5

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

The description states a clear action and scope: 'Run all security scanners in parallel (including service detection).' 'All scanners' distinguishes it from the individual scanner siblings at a glance, though it does not explicitly contrast it with scan_and_report.

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

Usage Guidelines3/5

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

The description implies when to use this tool by emphasizing broad coverage ('all security scanners') and multi-account support, but it does not state explicit when/how alternatives like scan_and_report, scan_group, or individual scanners should be used instead.

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