Usage Guidance
This skill is a lightweight, instruction-only invoice template and appears internally consistent. It does not request credentials or install software. Before installing/upgrading to any paid or automation companion (for example, the referenced "Invoice Tracker" or "Freelancer Revenue Engine"), review that skill’s declared requirements — especially any API keys, payment provider credentials, or install scripts — because automation/tracking features commonly require external access. Also avoid pasting highly sensitive data (full bank account numbers, unredacted SSNs, or private keys) into the agent’s chat unless you trust how the agent logs and handles conversation data.
Capability Analysis
Type: OpenClaw Skill
Name: invoice-template
Version: 1.0.0
The skill bundle contains only metadata (`_meta.json`) and a markdown file (`SKILL.md`) describing a simple invoice generation skill. The `SKILL.md` provides instructions for the AI agent to format user-provided details into an invoice. There are no executable code blocks, no attempts at prompt injection to subvert the agent's behavior, no requests for sensitive data, and no indicators of malicious activity, data exfiltration, or system compromise. The content is entirely aligned with its stated purpose.
Capability Assessment
Purpose & Capability
Name, description, and content all align: the skill is a simple invoice template generator and does not claim any additional capabilities that would require extra access or credentials.
Instruction Scope
SKILL.md contains only template text, examples, and an upsell. It does not instruct the agent to read files, access environment variables, call external endpoints, or collect unrelated system data.
Install Mechanism
There is no install specification and no code files — this is instruction-only, so nothing is written to disk or downloaded during install.
Credentials
The skill declares no required environment variables, credentials, or config paths; nothing in the instructions requires secrets or external service access.
Persistence & Privilege
always is false and there is no mechanism to persist or modify other skills or system settings. The skill does not request elevated persistence or privileges.
How to Use
- Make sure OpenClaw is installed (local or Docker)
