Invoice Generator

Generate professional Markdown invoices with multi-currency support, tax, discounts, payment details, and clear formatting for freelancers and small businesses.

Security Scan

The skill's instructions, requirements, and scope are internally consistent with an invoice-generation tool and it asks for no extra system credentials or installs.

Purpose & Capability

The name/description match the SKILL.md: it generates Markdown invoices, handles currencies/taxes/discounts, and asks for sender/recipient/line items. It declares no binaries, env vars, or installs—consistent with an instruction-only formatter/generator.

Instruction Scope

Runtime instructions stay within the invoice-generation task (prompt for sender/recipient/items, compute totals, produce Markdown). The only caution: the skill explicitly asks for payment details (bank, account, routing), which is expected for invoices but is sensitive user-supplied data—users should be careful what they paste into the agent.

Install Mechanism

No install spec and no code files (instruction-only). This minimizes on-disk execution risk; nothing will be downloaded or installed by the skill itself.

Credentials

The skill requests no environment variables, credentials, or config paths (appropriate). However, it prompts users to provide payment/account information within the chat flow—these are sensitive inputs provided by the user, not environment secrets, so treat them accordingly.

Persistence & Privilege

always is false and the skill has no install/install-time behavior. It does not request elevated or persistent platform privileges and does not modify other skills or system settings.

Assessment

This skill appears to do what it claims and doesn't request system credentials or install code. However, it will ask you to type payment details (bank/account/routing) into the chat to include them on invoices — only do that if you are comfortable with your agent/chat logs storing that information. If you prefer, use placeholders or redact sensitive numbers until you paste them into a locally stored final invoice, or use a dedicated invoicing/payment service for handling actual payments. Always review the generated invoice for correct calculations, currency formatting, and privacy before sending it to a client.

Create professional invoices in Markdown format. Supports multiple currencies, tax calculations, and standard invoice fields. Perfect for freelancers, consultants, and small businesses.
