[COMMAND_EXECUTION]: The file rules/transcribe-captions.md provides an example of using execSync from the child_process module to run ffmpeg for audio conversion. This is a common requirement for the Whisper transcription workflow to ensure audio is in the correct format.
[EXTERNAL_DOWNLOADS]: Several rule files recommend installing dependencies via standard package managers. These include official @remotion/* packages and widely-used libraries such as zod, mapbox-gl, and @turf/turf.
[REMOTE_CODE_EXECUTION]: The file rules/transcribe-captions.md demonstrates the use of the @remotion/install-whisper-cpp package to download and install the Whisper.cpp engine. This is a standard procedure for enabling local speech-to-text capabilities.
[DATA_EXFILTRATION]: Files like rules/calculate-metadata.md, rules/compositions.md, and rules/lottie.md include code snippets demonstrating the use of the fetch API to retrieve dynamic video props, metadata, or animation data from remote URLs.
[PROMPT_INJECTION]: An indirect prompt injection surface exists in rules/calculate-metadata.md and rules/display-captions.md through the ingestion of external data.
Ingestion points: rules/calculate-metadata.md (props.dataUrl), rules/display-captions.md (captions JSON), rules/import-srt-captions.md (SRT text).
Boundary markers: Not present in the provided code examples.
Capability inventory: Includes fetch (network access), execSync (system command execution for ffmpeg), and fs.writeFileSync (file system access).
Sanitization: No specific sanitization or validation logic is shown for external data sources.
