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
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00029 | $0.03751 |
| Opus 5 | $0.00015 | $0.01876 |
| Sonnet 5 | $0.00006 | $0.00750 |
| Haiku 4.5 | $0.00003 | $0.00375 |
Grade A, and why
document-gen-resilient-multiformat scanned grade A with 0 findings 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 10d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 472 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Resilient Document Generation Workflow (Multi-Format + Unicode-Safe)
When to Use
Use this skill when generating documents in multiple formats (.docx, .pdf, .html) and you need:
- Reliable execution with pre-flight environment verification
- Automatic Unicode handling based on target format
- Fallback options when primary tools (pandoc/LaTeX) are unavailable
- Clear error isolation through discrete, observable steps
Trigger this workflow when:
shell_agentreturns unknown/unclear errors on document generation- You need multiple output formats from one source
- Documents contain special characters, symbols, or non-ASCII text
- Previous PDF generation attempts failed due to encoding or missing dependencies
Pre-Flight Environment Check
Before starting, verify your environment has the required tools:
run_shell
command: which pandoc && pandoc --version | head -1
run_shell
command: which pdflatex || which xelatex || which wkhtmltopdf || echo "No PDF engine found"
run_shell
command: python3 -c "import fpdf; print('fpdf2 available')" 2>/dev/null || echo "fpdf2 not available"
run_shell
command: python3 -c "import reportlab; print('reportlab available')" 2>/dev/null || echo "reportlab not available"
If pandoc is missing: Install via apt-get install pandoc or brew install pandoc
If no PDF engine found: Choose fallback approach:
- Install LaTeX:
apt-get install texlive-latex-recommended texlive-fonts-recommended - Or use wkhtmltopdf:
apt-get install wkhtmltopdf - Or use Python fallback (fpdf2/reportlab) - see Alternative PDF Generation section
Core Technique
Split the workflow into discrete, observable steps with automatic format detection:
- Environment check → Verify tools are available
- Content creation → Use
write_fileto create source Markdown - Auto-sanitization → Conditionally sanitize based on target format (PDF needs it, DOCX/HTML don't)
- Format conversion → Use appropriate tool for each format with fallback options
- Verification → Check output files exist and validate content
What ships with it
2 files 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.

document-gen-resilient-multiformat is a skill published in the GitHub repository HKUDS/OpenSpace (7,552 stars, last pushed 28d ago), licensed MIT. It adds 29 tokens to every session and 3,751 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
