使用说明 (SKILL.md)
Invoice Generator
Generate professional PDF invoices from natural language or structured data. Works offline, no external service needed.
Quick Start
Tell your OpenClaw agent:
Generate an invoice for:
- Client: Acme Corp, 123 Main St, New York
- Items: Web Development 40 hours @ $150/hr, Server Setup 1x $500
- Tax: 10%
- Due: Net 30
- My company: Zac Tech LLC
The agent will use this skill to generate a professional PDF invoice.
Script Usage
python3 {baseDir}/scripts/gen_invoice.py \
--from "Your Company, 123 Street, City" \
--to "Client Name, 456 Ave, City" \
--items "Web Development|40|150" "Server Setup|1|500" \
--tax 10 \
--currency USD \
--due "Net 30" \
--number "INV-2026-001" \
--output invoice.pdf
Features
- 📄 Clean, professional PDF layout
- 💰 Multiple currencies (USD, EUR, GBP, CNY, JPY, AUD, etc.)
- 📊 Automatic subtotal, tax, and total calculation
- 🔢 Sequential invoice numbering
- 🇨🇳 CJK text support (Chinese/Japanese/Korean company names and items)
- 📝 Notes and payment terms field
- 🖨️ Print-ready A4 format
Item Format
Each item is a pipe-separated string: description|quantity|unit_price
"Website Design|1|2000"
"Hosting (monthly)|12|50"
"Content Writing|20|75"
Dependencies
pip3 install reportlab
For CJK support, install CJK fonts:
sudo yum install -y google-noto-sans-cjk-ttc-fonts # RHEL/CentOS
sudo apt install -y fonts-noto-cjk # Ubuntu/Debian
安全使用建议
This skill appears to be what it claims: an offline PDF invoice generator. Before installing/running: (1) ensure you install reportlab from PyPI (pip3 install reportlab) and any CJK fonts you actually need; the SKILL.md suggests using sudo apt/yum to install fonts — only do that on systems you control. (2) Review or run the included scripts/gen_invoice.py in an isolated environment if you have concerns about file writes; it only writes the specified output file but will search font directories. (3) Provide only expected invoice data as arguments and avoid running with elevated privileges unnecessarily. If you need network-isolated assurance, run it in a container/VM. Overall there are no credentials requested and no network calls or obfuscated code in the provided script.
功能分析
Type: OpenClaw Skill
Name: invoice-gen
Version: 1.0.0
The skill bundle is a legitimate utility for generating PDF invoices locally using the reportlab library. The Python script (scripts/gen_invoice.py) safely processes user-provided data to create formatted documents and includes logic to locate system fonts for CJK support without any evidence of data exfiltration, malicious execution, or prompt injection.
能力评估
Purpose & Capability
Name/description promise (generate PDF invoices, CJK support, offline) aligns with included assets: SKILL.md describes usage and dependencies and scripts/gen_invoice.py implements PDF generation with CJK font discovery and invoice formatting. No unrelated credentials, binaries, or services are requested.
Instruction Scope
SKILL.md instructs the agent to run the included Python script and to install reportlab and optional CJK fonts. The runtime instructions and script operate on provided invoice fields and an output path only; they do not read arbitrary user files, environment secrets, or contact network endpoints.
Install Mechanism
No install spec is provided; the skill is instruction-only with a bundled script. Declared dependency is pip install reportlab and optional OS package manager font installs — both are expected for PDF/CJK rendering. There are no downloads from untrusted URLs or archive extraction instructions.
Credentials
The skill requires no environment variables, credentials, or config paths. The script searches common font paths on disk (expected for CJK support) but does not access other system secrets or configuration.
Persistence & Privilege
The skill is not marked always:true and does not modify other skills or agent configuration. It runs as a one-off script that writes a user-specified output PDF path only.
