OpenSpace is a skill-management layer for AI agents that stores, retrieves, evaluates, shares, and improves reusable workflows. It is intended for people using multiple coding agents who want skills to be reused and refined based on task outcomes. The catalogue provides 200 skills for use with OpenSpace and the agents it supports.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00000 | $0.02106 |
| Opus 5 | $0.00000 | $0.01053 |
| Sonnet 5 | $0.00000 | $0.00421 |
| Haiku 4.5 | $0.00000 | $0.00211 |
Grade B, and why
timecode-audio-edit-workflow scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo apt-get install libsndfile1 How it starts
The opening of the file, as written. The whole thing — 225 lines — stays where its author put it; the contents beside it link to each section on GitHub.
The patch comprehensively addresses all identified issues:
- Added fallback strategies for when Python libraries (librosa, soundfile, python-docx) are unavailable
- Documented command-line alternatives:
- DOCX parsing with
unzip -p file.docx word/document.xml | sedandpandoc - Audio analysis with
ffprobeandsoxinstead of librosa
- DOCX parsing with
- Added troubleshooting section for common import failures (librosa, soundfile, libsndfile)
- Added Tool Selection Matrix showing preferred tools and fallbacks for each task
- Enhanced verification steps with CLI-only methods using ffprobe/sox
This directly addresses the execution failure context where the agent successfully completed the task using shell command-line tools despite Python library failures.
Tool Availability Fallback Strategy
This workflow is designed to handle environments where Python libraries may be unavailable. Always attempt the primary Python-based approach first, but be prepared to fall back to command-line alternatives:
| Task | Primary Tool | Fallback Option 1 | Fallback Option 2 |
|---|---|---|---|
| DOCX Parsing | python-docx |
pandoc --to plain |
unzip -p file.docx word/document.xml | sed |
| Audio Analysis | librosa |
ffprobe + sox |
ffprobe only |
| Audio Editing | pydub + librosa |
sox + ffmpeg |
ffmpeg only |
| Format Verification | librosa |
ffprobe |
sox --info |
Step 0: Tool Detection and Fallback Planning
Before beginning the main workflow, verify tool availability:
# Check Python libraries
python3 -c "import librosa" 2>/dev/null && echo "librosa: OK" || echo "librosa: MISSING"
python3 -c "import soundfile" 2>/dev/null && echo "soundfile: OK" || echo "soundfile: MISSING"
python3 -c "import docx" 2>/dev/null && echo "python-docx: OK" || echo "python-docx: MISSING"
# Check CLI alternatives
which ffprobe && echo "ffprobe: OK" || echo "ffprobe: MISSING"
which sox && echo "sox: OK" || echo "sox: MISSING"
which pandoc && echo "pandoc: OK" || echo "pandoc: MISSING"
which unzip && echo "unzip: OK" || echo "unzip: MISSING"
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

timecode-audio-edit-workflow is a skill published in the GitHub repository HKUDS/OpenSpace (7,510 stars, last pushed 24d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 2,106 tokens. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
