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.

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 | $0.00021 | $0.03179 |
| Opus 5 | $0.00010 | $0.01589 |
| Sonnet 5 | $0.00004 | $0.00636 |
| Haiku 4.5 | $0.00002 | $0.00318 |
Grade A, and why
document-gen-resilient-workflow 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 — 382 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Resilient Document Generation Workflow (Multi-Engine Fallback)
When to Use
Use this skill when document generation tasks fail or when shell_agent returns unknown errors, especially for:
- Generating documents in multiple formats (
.docx,.pdf,.html) - PDF generation fails due to missing LaTeX, encoding issues, or tool errors
- Documents contain special characters, symbols, or non-ASCII text
- You need maximum reliability with automatic fallback options
Core Technique
Split document generation into discrete, observable steps with cascading fallbacks for PDF generation:
- Content creation → Use
write_fileto create source Markdown - Unicode sanitization → Use Python script for reliable character replacement
- Format conversion → Try multiple PDF engines in sequence until one succeeds
- Verification → Check file exists, has non-zero size, and is valid
⚠️ Unicode & PDF Engine Guide
Different PDF engines have different Unicode support:
| Engine | Unicode Support | Best For | Fallback Position |
|---|---|---|---|
pdflatex |
Limited (ASCII-focused) | Simple documents | 1st (fastest) |
xelatex |
Full Unicode | Documents with non-ASCII | 2nd |
wkhtmltopdf |
Good Unicode | Web-style documents | 3rd |
reportlab (Python) |
Full control | Programmatic PDFs | 4th |
fpdf2 (Python) |
Full control | Simple text PDFs | 5th (last resort) |

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.

document-gen-resilient-workflow is a skill published in the GitHub repository HKUDS/OpenSpace (7,552 stars, last pushed 28d ago), licensed MIT. It adds 21 tokens to every session and 3,179 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.
