The Agent Skills Directory

[INDIRECT_PROMPT_INJECTION]: The skill processes untrusted presentation files (PPT, PPTX, PDF) to extract slide text and speaker notes, which are then used to generate narration scripts.
Ingestion points: The skill downloads files using okou web download-file and extracts content via okou presentation screenshot and manual parsing of deck data.
Boundary markers: Narration text is handled as file content and piped through standard input to generation tools, reducing but not eliminating the risk of command-like strings being interpreted by the narration provider.
Capability inventory: The skill possesses significant local capabilities including file system write access, execution of local scripts, and network rendering via cloud APIs.
Sanitization: The scripts/build-project.mjs script includes an escapeHtml function to prevent malicious text in slides from breaking the generated HTML composition project.
[COMMAND_EXECUTION]: The skill relies heavily on executing shell commands and local Node.js scripts to perform media processing and project assembly.
Evidence: SKILL.md contains numerous templates for okou, node, and npx commands. The helper scripts use node:child_process to invoke ffmpeg and ffprobe for media analysis.
[EXTERNAL_DOWNLOADS]: The skill downloads and executes an external package from the NPM registry at runtime.
Evidence: SKILL.md and scripts/build-project.mjs both invoke npx --yes hyperframes@0.8.26 to perform project validation and rendering tasks.
[DYNAMIC_EXECUTION]: The skill generates executable HTML and configuration files at runtime to define the video composition.
Evidence: The scripts/build-project.mjs script programmatically constructs an index.html file using slide paths and metadata, which is then 'executed' by the Hyperframes renderer to produce the final video.
