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 | $0.00023 | $0.02711 |
| Opus 5 | $0.00012 | $0.01355 |
| Sonnet 5 | $0.00005 | $0.00542 |
| Haiku 4.5 | $0.00002 | $0.00271 |
Grade A, and why
document-gen-unicode-safe 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 4d 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 — 302 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Document Generation Fallback Workflow (Unicode-Safe)
When to Use
Use this skill when shell_agent returns unknown or unclear errors on complex document generation tasks, especially when:
- Generating documents in multiple formats (e.g.,
.docx,.pdf,.html) - The error message doesn't provide clear debugging information
- You need to handle special characters, symbols, or non-ASCII text safely
- PDF generation fails due to LaTeX encoding issues
Core Technique
Instead of delegating the entire document generation to shell_agent, manually split the workflow into discrete, observable steps:
- Content creation → Use
write_fileto create source document (Markdown) - Unicode sanitization → Preprocess markdown to replace problematic characters before PDF conversion
- Format conversion with stderr capture → Use
run_shellwithpandocfor each target format, capturing full stderr output - Verification → Check output files exist and are valid
⚠️ Unicode & LaTeX Compatibility Warning
Critical: PDF generation via pandoc typically uses LaTeX (pdflatex or xelatex), which has limited Unicode support. Common problematic characters include:
| Character | Issue | Safe Replacement |
|---|---|---|
— (em dash) |
May not render | -- or - |
– (en dash) |
May not render | - |
" " (curly quotes) |
Encoding errors | " " (straight quotes) |
' ' (curly apostrophe) |
Encoding errors | ' (straight apostrophe) |
… (ellipsis) |
May not render | ... |
→ ← ↑ ↓ (arrows) |
LaTeX incompatibility | -> <- ^ v |
✓ ✗ (checkmarks) |
May not render | [x] [ ] |
★ ● (symbols) |
May not render | * - |
© ® ™ |
May require packages | (c) (r) (tm) |
| Non-ASCII letters (é, ñ, ü) | Font-dependent | Use xeLaTeX or replace |
Step-by-Step Workflow
Step 1: Create Source Content with write_file
Write your document content as Markdown to a temporary source file. This gives you full visibility into the content being generated.
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-unicode-safe is a skill published in the GitHub repository HKUDS/OpenSpace (7,501 stars, last pushed 22d ago), licensed MIT. It adds 23 tokens to every session and 2,711 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.
