Output Formats

Markdown (default)

Clean markdown table format, easy to paste into emails or docs.

HTML

Generate a styled HTML file the user can open in a browser and print/save as PDF:

  • Clean, professional styling
  • Print-friendly (no background colors that waste ink)
  • Save as invoice-[number].html

Rules

  • Always calculate totals correctly. Double-check math.
  • Invoice numbers should be sequential. Check for existing invoices if possible.
  • Due date = invoice date + payment terms (Net 30 = 30 days, etc.)
  • Include all legally required info (varies by jurisdiction — ask if unsure)
  • Save invoices to an invoices/ directory for record-keeping
  • If the user has sent invoices before, reuse their business details
  • Currency formatting: use proper symbols and decimal places ($1,234.56)

Recurring Invoices

If the user bills the same client regularly:

  • "Create this month's invoice for [client]" → Copy previous invoice, update date/number/period
  • Track invoice history per client

Quick Commands

  • "Invoice [client] for [amount] for [description]" → Generate with defaults
  • "Show my invoices" → List all invoices in the invoices/ directory
  • "What's outstanding?" → Show unpaid invoices past due date

Usage Guidance
This skill appears to do what it says: generate invoices and keep a local invoice history. Before installing, consider: (1) it will save invoices and business/client details to an invoices/ folder — avoid storing full bank account numbers or sensitive payment credentials in plain files; (2) confirm where the agent’s working directory is and whether those files are backed up or encrypted; (3) if you connect this agent to other skills (CRM, email-sender), review those integrations before sharing invoices; and (4) always review generated invoices before sending to clients. If you want stronger protection, run the skill in a restricted workspace or add file-encryption/secure storage for invoice data.
Capability Analysis
Type: OpenClaw Skill Name: afrexai-invoice-gen Version: 1.1.0 The skill is classified as suspicious due to its explicit instructions in `SKILL.md` for file system read and write operations, including saving invoices to an `invoices/` directory, checking for existing invoices, and listing all invoices. While these capabilities are necessary for the skill's stated purpose, they represent a significant level of access that could be exploited if the agent's environment is not properly sandboxed or if future versions introduce vulnerabilities like path traversal. Additionally, `SKILL.md` contains `clawhub install` commands, which, although likely intended for the user, could be misinterpreted by a less robust AI agent as commands to execute, potentially leading to unintended software installations.
Capability Assessment
Purpose & Capability
Name/description (generate invoices in Markdown/HTML) matches the SKILL.md: templates, formatting rules, math checks, and save/list behaviors are all coherent with an invoice generator. No unrelated credentials, binaries, or install steps are requested.
Instruction Scope
Instructions explicitly tell the agent to save invoices to an invoices/ directory, check existing invoices, reuse business details, generate HTML/Markdown, and compute totals/dates. These are expected for this skill, but they imply the agent will read/write files and persist personal/business data locally. The SKILL.md does not instruct any unexpected file reads, environment-variable access, or network exfiltration.
Install Mechanism
No install spec and no code files — instruction-only. This minimizes install-time risk because nothing is downloaded or executed from external URLs.
Credentials
The skill requests no environment variables, credentials, or config paths. That is appropriate for a local invoice generator and proportional to its functionality.
Persistence & Privilege
The skill asks the agent to persist invoices and business contact details locally (invoices/ directory) and to reuse saved info. This is normal for bookkeeping but does mean financial and PII will be stored on disk; review where the agent runs and where files are written. always:false and normal autonomous invocation are set (no elevated platform privileges).
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install afrexai-invoice-gen
  3. After installation, invoke the skill by name or use /afrexai-invoice-gen
  4. Provide required inputs per the skill's parameter spec and get structured output
