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.

SkillSpector: 1 finding, up to medium
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 | $0.00020 | $0.00967 |
| Opus 5 | $0.00010 | $0.00483 |
| Sonnet 5 | $0.00004 | $0.00193 |
| Haiku 4.5 | $0.00002 | $0.00097 |
Grade B, and why
pandoc-pdf-error-diagnosis 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.

A mod that escalates privileges can change anything on the machine, not only the project.

Pandoc PDF Error Diagnosis Workflow
When pandoc reports an "unknown error" during PDF conversion, follow this systematic diagnostic workflow to identify and resolve the issue.
Step 1: Verify Pandoc Installation
First, confirm pandoc is installed and check its version:
pandoc --version
This verifies pandoc is available and shows which version and features are supported.
Step 2: Check Available PDF Engines
Identify which PDF rendering engines are installed on the system:
which pdflatex xelatex lualatex wkhtmltopdf
Common engines and their characteristics:
- pdflatex: Fast, widely available, good for simple documents
- xelatex: Better Unicode/font support, handles modern fonts well
- lualatex: Advanced Lua scripting, modern TeX features
- wkhtmltopdf: HTML-to-PDF via WebKit, good for web-styled content
Step 3: Attempt Conversion with Explicit Engine
Try conversion with an explicit engine specification, starting with xelatex (most forgiving):
pandoc input.md -o output.pdf --pdf-engine=xelatex
Important: Capture the full stderr output for diagnosis:
pandoc input.md -o output.pdf --pdf-engine=xelatex 2>&1 | tee conversion.log
Step 4: Analyze Error Output
Examine the captured stderr for common issues:
| Error Pattern | Likely Cause | Solution |
|---|---|---|
xelatex not found |
Engine not installed | Install TeX Live or try different engine |
Package xyz not found |
Missing LaTeX package | Install missing package or remove feature |
Font xyz not found |
Missing font | Install font or change document fonts |
LaTeX Error: File xyz.sty not found |
Missing style file | Install texlive-extra or simplify document |
Step 5: Fallback Strategy
If the primary engine fails, try alternatives in order:
# Try pdflatex (most basic)
pandoc input.md -o output.pdf --pdf-engine=pdflatex 2>&1
# Try lualatex (if xelatex failed)
pandoc input.md -o output.pdf --pdf-engine=lualatex 2>&1
# Try wkhtmltopdf (for HTML-heavy content)
pandoc input.md -o output.pdf --pdf-engine=wkhtmltopdf 2>&1
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-diagnosis is a skill published in the GitHub repository HKUDS/OpenSpace (7,552 stars, last pushed 28d ago), licensed MIT. It adds 20 tokens to every session and 967 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.
