What it does

Document Gen Fallback is an agent skill from HKUDS/OpenSpace. Fallback workflow for multi-format document generation when shellagent encounters errors

Its SKILL.md is about 920 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.

It sits in Documents & Office. It works with Pandoc and Microsoft Word. The repository describes itself as: "OpenSpace: The Skill Management Layer for AI Agents" -- https://open-space.cloud/. The licence is MIT.

Workflow steps

3 steps, taken from the step headings in SKILL.md.

Create Source Content with write_file
Convert to Target Formats with run_shell
Verify Outputs

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:
- pandoc
- apt-get
- brew
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
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

Document Gen Fallback loads about 917 tokens when it runs. Until then it costs about 28 tokens; SKILL.md has 281 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~28
When it runs · the whole SKILL.md, loaded when a task matches: ~917

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.

description: Fallback workflow for multi-format document generation when shell_agent encounters errors

Document Generation Fallback Workflow

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 better visibility into each step of the generation process

Core Technique

Instead of delegating the entire document generation to shell_agent, manually split the workflow into discrete, observable steps:

Content creation → Use write_file to create source document (Markdown)
Format conversion → Use run_shell with pandoc for each target format
Verification → Check output files exist and are valid

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.

write_file
path: /tmp/document_source.md
content: |
  # Document Title
  
  ## Section 1
  Content here...
  
  ## Section 2
  More content...

Step 2: Convert to Target Formats with run_shell

Use run_shell with explicit pandoc commands for each format. This isolates conversion errors.

run_shell
command: pandoc /tmp/document_source.md -o output.docx

run_shell
command: pandoc /tmp/document_source.md -o output.pdf

Step 3: Verify Outputs

Check that files were created successfully:

run_shell
command: ls -lh output.docx output.pdf

Complete Example

markdown

# Generate Negotiation Strategy Document

## Step 1: Write Markdown source
write_file
path: /tmp/negotiation_strategy.md
content: |
  # Negotiation Strategy
  
  ## Executive Summary
  [Content...]
  
  ## Resolution Path
  [Content...]
  
  ## BATNA Analysis
  [Content...]

## Step 2: Convert to DOCX
run_shell
command: pandoc /tmp/negotiation_strategy.md -o negotiation_strategy.docx

## Step 3: Convert to PDF
run_shell
command: pandoc /tmp/negotiation_strategy.md -o negotiation_strategy.pdf

## Step 4: Verify
run_shell
command: ls -lh negotiation_strategy.*

Advantages Over shell_agent

Aspect	shell_agent	Manual Workflow
Error visibility	Opaque, may retry silently	Each step shows explicit output
Recovery	Automatic but may loop	Manual intervention at specific step
Debugging	Hard to isolate failure point	Clear which step failed
Control	Agent decides approach	You control each conversion

Common pandoc Commands

bash

# Markdown to Word
pandoc input.md -o output.docx

# Markdown to PDF (requires LaTeX or wkhtmltopdf)
pandoc input.md -o output.pdf

# Markdown to HTML
pandoc input.md -o output.html

# With custom template
pandoc input.md --template=template.html -o output.html

# With metadata
pandoc input.md -o output.pdf --metadata title="Document Title"

Troubleshooting

PDF generation fails: Ensure LaTeX is installed (texlive package) or use --pdf-engine=wkhtmltopdf
DOCX formatting issues: Add --reference-doc=template.docx for custom styles
Unicode/encoding errors: Add -f markdown+utf8 to pandoc command
Missing pandoc: Install via apt-get install pandoc or brew install pandoc

When to Return to shell_agent

After successfully completing the manual workflow once, you can attempt shell_agent again for similar tasks, now with a known-working fallback if errors recur.
