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.

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 | $0.00796 |
| Opus 5 | $0.00010 | $0.00398 |
| Sonnet 5 | $0.00004 | $0.00159 |
| Haiku 4.5 | $0.00002 | $0.00080 |
Grade A, and why
pandoc-unicode-sanitize 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 3d 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pandoc Unicode Sanitization for PDF Conversion
Problem
LaTeX (used by pandoc for PDF output) may fail or produce errors when encountering non-ASCII Unicode characters like currency symbols (₹, €, £), special quotes, or other Unicode characters not supported by the default LaTeX engine.
Solution
Pre-process Markdown files to replace problematic Unicode characters with ASCII equivalents before running pandoc PDF conversion.
Steps
1. Identify Problematic Characters
Common problematic characters include:
- Currency symbols: ₹, €, £, ¥
- Special quotes: " " ' '
- Arrows: →, ←, ↑, ↓
- Bullets: •, ◦
- Other symbols: ©, ®, ™, ±, ×, ÷, —, –
2. Create a Sed Substitution Script
Create a shell script for reusable sanitization:
#!/bin/bash
# sanitize-for-pdf.sh
sed -e 's/₹/Rs/g' \
-e 's/€/EUR/g' \
-e 's/£/GBP/g' \
-e 's/¥/JPY/g' \
-e 's/"/"/g' \
-e 's/"/"/g' \
-e "s/'/'/g" \
-e "s/'/'/g" \
-e 's/→/->/g' \
-e 's/←/<-/g' \
-e 's/•/-/g' \
-e 's/©/(c)/g' \
-e 's/®/(R)/g' \
-e 's/™/(TM)/g' \
-e 's/±/+/ -/g' \
-e 's/×/x/g' \
-e 's/÷/\//g' \
-e 's/—/--/g' \
-e 's/–/-/g' \
"$1"
3. Run Sanitization Before Pandoc
# Using the script
./sanitize-for-pdf.sh input.md > sanitized.md
pandoc sanitized.md -o output.pdf
# Or inline
cat input.md | sed 's/₹/Rs/g; s/€/EUR/g; s/£/GBP/g' | pandoc -o output.pdf
4. Alternative: Use iconv for Automatic Transliteration
For broader Unicode coverage:
iconv -f UTF-8 -t ASCII//TRANSLIT < input.md > sanitized.md
pandoc sanitized.md -o output.pdf
5. Alternative: Use XeLaTeX or LuaLaTeX Engine
If you want to preserve Unicode characters, use a Unicode-capable engine:
pandoc input.md -o output.pdf --pdf-engine=xelatex
# or
pandoc input.md -o output.pdf --pdf-engine=lualatex
Best Practices
- Sanitize files before conversion rather than debugging LaTeX errors after
- Keep a mapping of your organization's common symbols and preferred replacements
- Test with a small sample before processing large documents
- Consider using XeLaTeX/LuaLaTeX if Unicode preservation is required
- Document which characters cause issues in your specific environment
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-unicode-sanitize is a skill published in the GitHub repository HKUDS/OpenSpace (7,510 stars, last pushed 25d ago), licensed MIT. It adds 21 tokens to every session and 796 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 2026-09-03.
