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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00022 | $0.00862 |
| Opus 5 | $0.00011 | $0.00431 |
| Sonnet 5 | $0.00004 | $0.00172 |
| Haiku 4.5 | $0.00002 | $0.00086 |
Grade B, and why
pandoc-pdf-error-recovery 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 6d 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.

Pandoc PDF Error Recovery
Overview
When pandoc fails to convert documents to PDF with an "unknown error" or similar vague message, follow this systematic diagnostic and recovery workflow.
Step-by-Step Procedure
1. Verify Pandoc Installation
First confirm pandoc is installed and accessible:
pandoc --version
If this fails, install pandoc before proceeding:
- macOS:
brew install pandoc - Linux:
sudo apt-get install pandocorsudo yum install pandoc - Windows: Download from https://pandoc.org/installing.html
2. Check Available PDF Engines
Identify which PDF rendering engines are available on the system:
which pdflatex xelatex lualatex wkhtmltopdf context
Common engines and their typical use cases:
- pdflatex: Standard LaTeX, fast but limited Unicode support
- xelatex: Full Unicode support, recommended for most modern documents
- lualatex: Lua scripting support, good for complex layouts
- wkhtmltopdf: HTML/CSS rendering, good for web-style documents
- context: ConTeXt typesetting system
3. Attempt Conversion with Explicit Engine
Try conversion with xelatex first (most versatile for general documents):
pandoc input.md -o output.pdf --pdf-engine=xelatex 2>&1 | tee conversion.log
The 2>&1 | tee pattern captures both stdout and stderr to a log file for analysis.
4. Analyze Error Output
If conversion fails, examine the captured log:
cat conversion.log
Common error patterns and solutions:
- Missing LaTeX packages: Install with
tlmgr install <package>or system package manager - Font issues: Specify fonts with
-V mainfont="Font Name" - Missing engine: Fall back to available engine (go to Step 5)
5. Try Alternative Engines
Systematically try other available engines:
# Fallback to pdflatex
pandoc input.md -o output.pdf --pdf-engine=pdflatex 2>&1 | tee conversion-pdflatex.log
# Or try wkhtmltopdf for HTML-rich content
pandoc input.md -o output.pdf --pdf-engine=wkhtmltopdf 2>&1 | tee conversion-wkhtmltopdf.log
# Or try lualatex for complex documents
pandoc input.md -o output.pdf --pdf-engine=lualatex 2>&1 | tee conversion-lualatex.log
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.

pandoc-pdf-error-recovery is a skill published in the GitHub repository HKUDS/OpenSpace (7,552 stars, last pushed 28d ago), licensed MIT. It adds 22 tokens to every session and 862 once invoked, about $0.0001 per session on Opus 5. 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.
