Use this skill when diagnosing IAM and access failures for Bedrock and SageMaker. It traces the authorization chain — caller identity, iam:PassRole, trust policy, role permissions, resource policies, SCPs — to name the denying hop and propose a scoped policy. Read-only. Use when a Bedrock or SageMaker call fails on permissions: InvokeModel or Converse AccessDeniedException, CreateTrainingJob or CreateEndpoint AccessDenied, "is not authorized to perform", "not authorized to perform: iam:PassRole", or an execution role that cannot reach S3, ECR, or KMS. Also covers Marketplace and model-subscription denials that are not IAM gaps, and failures under non-access codes: ValidationException "Could not assume role" (trust-policy gap) or "No S3 objects found under S3 URL" (execution role cannot list the prefix). Do NOT use for IAM questions outside AI/ML, policy authoring or least-privilege review without a failure, throttling or quota errors (ThrottlingException), model quality issues, or non-

Generate original one-ink or controlled two-ink editorial images from any theme, sentence, article idea, object, or reference photo. Always use this skill when the user asks for 单色海报、双色印刷、单色调视觉、蓝色/绿色孔版印刷、risograph、网点照片、复古或当代编辑排版、zine poster, monochrome editorial poster, duotone print, or asks to use the mono-color style. It uses an adaptive white, gray, or pale-beige substrate, no more than two printing inks, active negative space, terse human language, and strong serif/grotesk/mono typography without making retro styling the default or copying a source composition, wording, logo, or artwork. Produce both the final generation prompt and the generated raster image unless the user explicitly asks for prompt only.
