Is it compatible with Linux and macOS?

Yes, it is designed to work on both platforms, provided the required CLI tools like asciinema and zstd are installed.

What is idle-based chunking?

The skill monitors your terminal activity; when it detects a pause (default 30 seconds), it triggers a chunk upload. This ensures your progress is saved periodically without interrupting active typing.

Will these recordings clutter my main repository?

No. The skill uses a git orphan branch which maintains a completely separate history, ensuring your main branch and PRs remain clean and focused on code.

Why does it use both zstd and brotli?

Zstd is used for initial streaming because it allows data to be appended easily. Brotli is used for final archival via GitHub Actions because it offers superior compression ratios for static files.

Does it work with multiple GitHub accounts?

Yes, the skill automatically probes SSH configs, gh CLI status, and environment variables to let you choose the correct account for storage.

生产力与工作流

Stream terminal recordings to GitHub in real-time using intelligent idle-based chunking and high-efficiency compression.

The Asciinema Streaming Backup skill provides a robust framework for automatically recording and archiving terminal sessions. It leverages zstd for concatenatable streaming and idle-detection to intelligently chunk data during 30-second pauses. By utilizing GitHub orphan branches, the skill ensures that recording history remains entirely separate from your main project codebase, preventing repository bloat while providing a permanent audit trail. For long-term storage, it integrates with GitHub Actions to recompress recordings using Brotli, achieving up to 300x compression ratios for maximum storage efficiency.
