The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill processes project files that are likely to contain user-supplied data, creating a surface for indirect prompt injection.
Ingestion points: The library scripts/lib/frame-packets-core.mjs reads STORYBOARD.md, frame.md, and SCRIPT.md from the project directory.
Boundary markers: Content from these files is inlined directly into 'frame packets' (e.g., .hyperframes/frame-packets/<id>.md) using standard Markdown headers (e.g., ## Assigned storyboard block), but lacks robust escaping or 'ignore' instructions for the embedded content.
Capability inventory: The system uses these packets to prompt sub-agents that have access to file-writing tools (writeFileSync), directory creation (mkdirSync), and internal project scripts.
Sanitization: No sanitization or filtering is performed on the extracted content before it is inlined into the sub-agent's prompt context.
[COMMAND_EXECUTION]: The skill relies on and documents the execution of various CLI tools and scripts.
The documentation in references/brief-contract.md describes executing a Node.js script from an external skill directory: node <MEDIA_DIR>/scripts/prefs.mjs get --hyperframes <MEMORY_ROOT> --json.
The SKILL.md file instructs the agent to use npx hyperframes for checking, snapshotting, and rendering projects.
[DYNAMIC_EXECUTION]: The framework's core design involves executing scripts at runtime within the composition environment.
references/sub-compositions.md explains that the runtime fetches HTML files, parses them, and executes <script> tags found inside <template> elements.
references/determinism-rules.md notes that these scripts are used to register timelines on window.__timelines and drive animations frame-by-frame.
[EXTERNAL_DOWNLOADS]: The skill references external resources for animation and styling from well-known services.
Compositions fetch the GSAP animation library from https://cdn.jsdelivr.net/npm/gsap@3.14.2/dist/gsap.min.js.
Tailwind projects utilize the browser runtime from a pinned version of @tailwindcss/browser@4.2.4.
