The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill processes and renders CloudFormation templates which can be sourced from external or third-party repositories.
Ingestion points: Templates and stack policies are ingested from local paths or remote URIs (Git/S3) defined in the source or path fields.
Boundary markers: Supports escaping for Go template delimiters to prevent unintended rendering, though it relies on the user to ensure template integrity.
Capability inventory: Executes stack mutations via AWS CloudFormation API, manages S3 artifact backends, and triggers lifecycle hooks.
Sanitization: Includes local validation for IAM capabilities and a presentation-layer masker to redact secrets in CLI output.
[EXTERNAL_DOWNLOADS]: Implements a JIT-vendoring mechanism to fetch templates from remote locations.
Evidence: The source.uri field allows fetching components from Git repositories and S3 buckets at runtime.
Context: This is a core feature for infrastructure-as-code orchestration, enabling versioned template management.
[COMMAND_EXECUTION]: Mentions the availability of a !exec function within templates and hooks.
Evidence: Documentation notes that !exec can be used within the Atmos environment for dynamic value resolution.
Context: The usage is presented as a developer feature for custom orchestration logic within a controlled Atmos environment.
