What it does
PDF Gen Fallback Dee20c is an agent skill from HKUDS/OpenSpace. Fallback workflow for document generation when code sandbox returns opaque errors
Its SKILL.md is about 910 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
It sits in Documents & Office, covering PDF. It works with Python. The repository describes itself as: "OpenSpace: The Skill Management Layer for AI Agents" -- https://open-space.cloud/. The licence is MIT.
When your agent uses it
- Tasks that involve PDF
Example prompts
- “/pdf-gen-fallback-dee20c”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 3827781. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
pythonpip
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use pip, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
PDF Gen Fallback Dee20c loads about 910 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 239 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- Fallback workflow for document generation when code sandbox returns opaque errors
PDF Generation Fallback Workflow
Purpose
When execute_code_sandbox returns opaque or unhelpful errors during document/PDF generation, use run_shell with direct python -c execution as a reliable alternative. This pattern includes library availability checks and explicit error handling.
When to Use
execute_code_sandboxfails with unclear error messages during document generation- PDF, report, or document creation tasks are failing unexpectedly
- You need more control over the Python execution environment
Step-by-Step Instructions
1. Check Library Availability
Before attempting generation, verify required libraries are installed:
run_shell: python -c "import reportlab; print('reportlab OK')"
run_shell: python -c "import fpdf; print('fpdf OK')"
run_shell: python -c "import PyPDF2; print('PyPDF2 OK')"If a library is missing, install it:
run_shell: pip install reportlab --quiet2. Execute Generation via run_shell
Instead of execute_code_sandbox, use run_shell with python -c:
run_shell: python -c "
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
c = canvas.Canvas('output.pdf', pagesize=letter)
c.drawString(100, 750, 'Document Content')
c.save()
print('PDF generated successfully')
"3. Handle Errors Explicitly
Wrap generation code with try/except and capture stderr:
run_shell: python -c "
import sys
try:
# Your generation code here
from reportlab.pdfgen import canvas
c = canvas.Canvas('output.pdf')
c.drawString(100, 750, 'Content')
c.save()
print('SUCCESS: PDF created')
sys.exit(0)
except Exception as e:
print(f'ERROR: {type(e).__name__}: {e}', file=sys.stderr)
sys.exit(1)
" 2>&14. Verify Output File
After generation, confirm the file was created:
run_shell: ls -la output.pdf
run_shell: file output.pdf5. Fallback Hierarchy
If the first approach fails, try alternatives in this order:
reportlab- Full-featured PDF generationfpdf- Simpler PDF librarywkhtmltopdf- HTML to PDF conversion- Direct text/Markdown output as last resort
Example: Complete Workflow
# Step 1: Check library
run_shell: python -c "import reportlab; print('OK')"
# Step 2: Generate with error handling
run_shell: python -c "
import sys
try:
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
c = canvas.Canvas('report.pdf', pagesize=letter)
c.setTitle('Surveillance Report')
c.drawString(100, 750, 'Revised Surveillance Report')
c.drawString(100, 730, 'Summary: Key findings documented')
c.save()
print('SUCCESS')
except Exception as e:
print(f'FAILED: {e}', file=sys.stderr)
sys.exit(1)
"
# Step 3: Verify
run_shell: test -f report.pdf && echo 'File exists' || echo 'File missing'Troubleshooting
| Issue | Solution |
|---|---|
| Module not found | pip install <module> --quiet |
| Permission denied | Check output directory permissions |
| Font errors | Use default fonts or install font packages |
| Encoding issues | Specify encoding explicitly in string operations |
Best Practices
- Always capture both stdout and stderr for debugging
- Exit with proper status codes (0 for success, 1 for failure)
- Keep generation code concise when using
python -c - For complex generation, write a temporary
.pyfile instead - Test library availability before attempting generation
